A high capacity trench system for in-floor wire management.
The Hubbell Trench system is an in-floor wire management system for high capacity wiring needs that require multiple circuit separation. Trench duct is commonly used as a feeder system for medical wall duct when installing radiology equipment such as X-Ray and MRI machines. Trench duct is also used as a stand alone system for commercial and retail applications where ease of access and high capacity are crucial variables.
Key Features Benefits• High capacity design supports
large wiring for single and multiple service requirements
• Open top design allows wire to be easily laid in duct
• Cover plates are removable and adjust horizontally to any point along the duct. Custom lengths of trench and fittings are available. Provided in either galvanized G90 steel or nonferrous aluminum
• Multiple compartment options allows for multiple circuit and low voltage separation
• Innovative duct support assembly allows for pre-pour leveling
• Packaging and labeling by project floor and room is available
Hubbell Wall Duct SeriesThe Hubbell Wall Duct is a UL Listed metal raceway system designed for the enclosure of wiring for MRI or X-Ray equipment in medical applications.
The system provides complete lay-in wiring capability in order to accommodate the large cables and connectors used in today’s installations.
Hubbell Wall Duct is available in either flush or surface mount and a combination will usually be required on any job. Vertical runs in the walls are usually flush mounted with horizontal runs on walls and all duct in ceiling plenum are typically surface type.
Key Features Benefits• Lay in wiring accommodates large
cables and connectors to connect equipment
• Corrosion resistant galvanneled A60 steel or non ferrous aluminum versions
• Flush (primarily wall) and Surface (primarily ceiling) mount provides placement flexibility and unique design requirements
• Packaging and labeling by project floor and room is available
