Latch Selection Guide for EnclosuresAs an experienced leader in engineered access hardware solutions for enclosures in a variety of applications, Southco offers hundreds of latch solutions. To make it easier for you to narrow down the best options for your installation, our applications engineers have outlined some key design considerations that impact enclosure performance and economy. They can also provide the direct benefit of their expertise in specific enclosure environments and applications.

Physical Latch Style ConsiderationsMost latch styles offer some degree of choice in terms of the door/frame interface, locking/security options, and mounting flexibility. But certain enclosure designs might demand specific latch formats to satisfy unique requirements of fit, operation, suitability for extreme demands, etc. Use these guidelines to help you narrow your choice of latch styles early in your decision-making process.

Cam Latches Are you looking for quick, simple, economical latching alternatives?

... do you need a degree of flexibility to compensate for variations in material dimensions or changing grip dimensions?

If so, then cam latches can be a cost-effective answer.

Compression Latches Does your application require gaskets or environmental sealing to satisfy specific industry standards (e.g., NEMA 4, IP-66, etc.) or to provide general protection against dust, rain, or electromagnetic interference (EMI) or radio frequency interference (RFI)?

... is your application subject to vibration or rattle caused by running motors, pumps or off-highway travel?

... do you need a tighter grip to reduce noise caused by loose fitting doors?

Each of these examples represents a good reason for selecting compression latches. Choose the specific style of compression latch you might need—fixed or adjustable compression, tool- or hand-actuated, locking or non-locking—based on your enclosure design and installation environment.

Draw Latches Does your enclosure have co-planar panels?

... do you need to compensate for some misalignment in the mating of the two panels?

... are you latching clam-shell style enclosures?

Unlike some latches that simply pin the door to the frame, draw latches can actually draw two panels or a panel and a frame together in the same plane. Various lever-action and rotary-action draw latch styles provide varying amounts of draw and can provide relatively high working loads.

Electronic Access Solutions (EAS)Do you need to monitor access to your enclosure?

... does your system require management of multiple key codes?

... does the enclosure need to open automatically when environmental conditions become severe?

... do you need to operate the lock or latch from a remote location?

If any of these scenarios apply, then an electronic latch should meet your needs. Various electronic latching styles are available including push-to-close, swinghandle or rotary action. Each latch offers flexibility in access control such as key pad, card swipe, key fob, biometric reader, cell phone, etc.

Push-To-Close Latches Are you interested in providing the most user-friendly operation for frequent access and closure?

... do you like the convenience of “slam-shut” operation, in both locking and non-locking applications?

... are there advantages to providing quick and easy enclosure access through a simple push, pull, or slide of the latch?

In these cases, your application could be a candidate for a convenient push-to-close latch style, provided that your grip tolerances and frame edge location are compatible with the selected latch design.

Multi-point Latches Do your enclosure doors cover a large span?

... is your door panel thin enough that its corners flex out even when the door is latched?

... do you have concerns about vandalism or unauthorized access on doors that can be pried open at the corners?

... are the contents of your enclosure extremely sensitive, valuable or critical to system performance?

In these instances, multi-point latches can provide a single point of actuation to engage multiple points of latching contact for more consistent and more secure latching. Various multi-point latching solutions include compression, locking, or hidden actuator features for added performance and security. Some are self-contained systems, while others can be ordered as add-on options used to supplement individual cam, compression or even push-to-close latches.

Design considerations.Use the following characteristics, definitions and descriptions to help you understand and evaluate your options outlined in the latch selection chart inside this booklet.

Access Control: Different latch operation styles—key-lockable, tool-restricted access or hand accessible without keys or special tools—contribute toward the degree of control over who can access an enclosure. (Also see “vandal resistance.”)

Adjustability: Does the latch design permit adjustment of its grip? This is typically done by setting the positions of adjusting nuts and screws. Self-adjusting latches provide adjustment for both grip and compression by means of a specially designed cam.

Common Key Code: This description indicates whether a particular latch class is able to share the same key code as other lockable latches from Southco, when desired.

Compression: Does your cabinet design require mechanical advantage from the latch to pull the door into the frame? Southco defines com pression as the distance of the pull-up required. Compression facilitates sealing, elimination of noise and rattle and compensation for tolerances and misalignment. Compression can be achieved in one of two ways—by rotating a ramped cam against the frame or with a clamping mechanism built into the latch.

Concealed: The decision to use concealed mounting hardware is usually driven by industrial design/appearance concerns or vandal-resistance requirements.

Corrosion Resistance (Salt-Spray Test): What level of corrosion protection is required of the access hardware? This is usually expressed in terms of hours of salt-spray exposure per ASTM B-117. In some cases, users will simply mandate the use of 300-Series stainless steel.

EMI Shielding: The level of electromagnetic interference shielding is typically defined as the degree of attenuation at a specified frequency. EMI performance can vary by enclosure application. Southco latches indicated for potential use in EMI shielding applications should be evaluated in the specific enclosure design.

Environmental Sealing: This reflects the level of sealing suitable for enclosures to prevent entrance of dust, water and other contaminants into the enclosure. (e.g., NEMA 4, IP-66)

External Protrusion/Flush Mount Hardware: How much room is available outside the enclosure for the latch hardware? Must it be totally flush for space or safety considerations? Can the mounting hardware extend beyond the interior surface of the enclosure? Protrusion is typically measured in millimeters.

Grip: What is the dimension from the surface on which the latch is mounted to the latch’s point of contact on the frame when the door is closed? Grip is typically expressed in millimeters.

Inside/Outside the Gasket: Where will latches be installed—inside or outside the gasket-sealed area? Latches suitable to be installed inside the sealed (gasketed) area must be sealed to the same level as the enclosure. Latches that are installed outside of the sealed area often do not need to be sealed.

Internal Protrusion/Surface Mount Hardware: How much room is available for the mounting hardware to protrude into the enclosed space? Protrusion is typically expressed in millimeters.

Door Thickness: The thickness of the door in which the latch will be installed, expressed in millimeters.

Seismic: Is seismic (earthquake) testing required? Does your enclosure need to be seismic rated? Seismic testing is conducted on the whole enclosure systems, not just the hardware. Southco latches suggested for seismic-rated enclosure use should be evaluated in the specific enclosure design.

Single-point or Multi-point: Does the enclosure specification require single-point or multi-point latching? This requirement is often driven by the need for gasket compression or vandal resistance, or by doors with long spans—where flexing of the door panel can cause a poor seal or rattling.

Size of Latch: Use the following scale as a guide for matching latch size to enclosure size.

Small = ≤ 40 mm2

Medium = 40 mm2 to 100 mm2

Large = ≥ 100 mm2

Vandal Resistance: The level of resistance to access by unauthorized persons. Usually expressed in time, with a specified set of tools. Southco has developed the following rating system:

VR 0 = Provides no resistance to forced entry

VR 1 = Limited resistance to forced entry by available tools (withstands 2-minute vandal test with pocket knife and screwdriver)

VR 2 = Provides resistance to deliberate forced entry with common tools (withstands 5-minute vandal test with hammer, screwdriver and pliers)

VR 3 = Prevents access with heavy duty tool set (withstands 5-minute vandal test with large hammer, chisel and pry bar)

VR 4 = Prevents access with heavy duty tool set (withstands 5-minute vandal test up to and including 10 V cordless drill or saw)

Vibration/Shock Resistance: The level of vibration to which the enclosure will be subjected. This is usually expressed in G-forces in a given direction for a given duration.

Remember, when specifying some cam latches you need to specify left-hand or right-hand operation. (See additional info on Web site or product literature.) You always want the cam to be open at the 12 o’clock position and engaged at the 3, 6 or 9 o’clock position. If the latch is installed so it is open at the 6 o’clock position, vibration and/or gravity could cause the cam to fall down into the open position and disengage from the frame.

Hinge Selection Guide for EnclosuresAs an experienced leader in engineered access hardware solutions for a variety of enclosure applications, Southco offers hundreds of hinge solutions. To help you narrow down those options for your enclosure installation, we have organized them by functionality, and outlined some key design considerations that can impact enclosure performance and economy. And we are constantly adding new solutions, so if you don’t see one here that suits your specific needs, contact one of our applications engineers for assistance.

Physical Hinge Style ConsiderationsSouthco offers hinges in a wide range of sizes, styles, and materials. All provide basic access to enclosures of varying designs. First, choose your hinge installation style: external, embedded, or concealed. Next, consider what additional functions you may want the hinge to provide, such as detent positioning or door removability. Then refer to the chart on the inside of this document to determine which product class provides the complete range of options you require.

HingesExternal HingesDo you need to maximize available space inside the enclosure?

... are you looking for a drop-in replacement that meets most standard panel preps?

Then an external hinge is for you. Southco has a wide range of mounting options to suit most door and frame configurations, and provide easy installation.

Do you need to attach or remove a door without tools?

... does the door need to hold open or closed?

... is the hinge being used on a heavy duty enclosure?

With materials ranging from light-weight plastics to heavy-duty cast stainless steel, and a wide range of sizes and installation styles, Southco has a hinge to meet your application needs. We have hinges to fit the most common door and frame configurations, as well as customized solutions to suit specific needs of individual applications.

Concealed HingesDoes the design of your cabinet require the hinge need to be invisible when the door is closed?

... does your hinge need to be inside the enclosure?

If so, a concealed hinge could be the solution for you. By concealing the hinge, the industrial design of the enclosure can shine through. Southco's concealed hinges combine hidden mounting with simple installation.

Positioning MechanismsEmbedded HingesDoes your design need to seamlessly integrate position control features into any application?

... does the shape and size need to fit in a small envelope of the application?

... does the hinge need to be molded-in or concealed with snap on covers?

Embedded hinges can be designed-in to become an integral part of any application. These hinges allow for a variety of positioning control options while fitting into an existing envelope for both small and large applications.

Need a tilt and swivel mechanism to control rotation in multiple axes?

... need to make a heavy object easier to move?

... need an object to deploy automatically when a latch is released?

When the requirement for motion management goes beyond a simple rotational motion, Southco's custom engineered positioning mechanisms can provide new levels of refinement and functionality to meet any motion management challenge. Whether your application requires torque, detent, bi-stable or counterbalance features, Southco has a solution to meet your specific needs.

Design considerations.Use the following characteristics, definitions, and descriptions to help you understand and evaluate your options outlined by the hinge selection chart inside this document.

Angle of Opening: At what predetermined angle(s) might the hinge position the open door? Or is the angle of positioning user controlled, as with a friction hinge? What is the total range of motion or maximum angle to which the hinge will open?

Concealed: Does the hinge or mounting hardware need to be concealed? This can be accomplished with internally mounted hinges, or by using a welded, thread-stud, or tapped-hole installation style. Such a decision is usually driven by industrial design/appearance concerns or vandal resistance requirements.

Corrosion Resistance (Salt Spray Test): What level of corrosion protection is required of the access hardware? This is usually expressed in terms of hours of salt-spray exposure per ASTM B-117. In some cases, users will simply mandate the use of 300 Series stainless steel.

Door Removal: Does the hinge need to separate into two pieces in order to allow the door to be removed from the frame for installation access or aisle clearance? Does it simply lift off, or is there a catch/release feature?

Embedded: Designed to be shrouded within the enclosure housing. Embedded hinges provide added functions like position control.

Environmental Sealing: This reflects the level of sealing suitable for enclosures to prevent entrance of dust, water and other contaminants into the enclosure. Most styles of hinges can achieve environmental sealing if properly gasketed. (e.g., NEMA 4, IP-66)

External: Mounts on the outside surface of the enclosure. Provides easy installation and maximizes interior enclosure space.

Hinge Material: The material used in the construction of the hinge (e.g., steel, stainless steel, zinc alloy, etc.) can affect maximum working load, corrosion resistance, and finish options.

Installation: How the hinge will be attached to the door and frame—welded, or with threaded bolt, through bolt, rivet, or screw mounting hardware? Defines the mechanical means used to attach the hinge to the door/frame.

Door Thickness: The thickness of the door in which the hinge will be installed, expressed in millimeters.

Position Control: What type of feature will be used to control the position of the hinge and door—detents, constant torque, adjustable torque, self-closing, dampened action, etc.

Seismic: Is seismic (earthquake) testing required? Does your enclosure need to be seismic rated? Seismic testing is conducted on the whole enclo sure system, not just the hardware. Southco hinges suggested for seismic-rated enclosure use should be evaluated in the specific enclosure design.

Size of Hinge: Use the following scale as a guide for matching hinge size to enclosure size.Small = ≤ 40 mm2

Medium = 40 mm2 to 80 mm2

Large = ≥ 80 mm2

Vandal Resistance: The level of resistance to access by unauthorized persons, usually expressed in time, with a specified set of tools. Southco has developed the following rating system:VR 0 = Provides no resistance to forced entry

VR 1 = Limited resistance to forced entry by available tools (withstands 2-minute vandal test with pocket knife and screwdriver)

VR 2 = Provides resistance to deliberate forced entry with common tools (withstands 5-minute vandal test with hammer, screwdriver and pliers)

VR 3 = Prevents access with heavy duty tool set (withstands 5-minute vandal test with large hammer, chisel and pry bar)

VR 4 = Prevents access with heavy duty tool set (withstands 5-minute vandal test up to and including 10 V cordless drill or saw)
