MATERIALUnistrut pipe clamps, unless noted, are punch-press made from hot-rolled, pickled and oiled steel plates, strip or coil, and conform to ASTM specifications A1008, A575, A576, A635, or A36. The fitting steel also meets the physical requirements of ASTM A1011 SS GR 33. The pickling of the steel produces a smooth surface free from scale.

• Electro-galvanized (EG), conforming to ASTM B633 Type III SC1
• Hot-dipped galvanized (HG), conforming to ASTM A123 or A153 (hardware)

DESIGN BOLT TORQUE
Note: When tightening 1⁄4" screws used with a two piece pipe clamp, a torque of 5 foot pounds (60 inch-pounds) should be used.
DESIGN LOADDesign load data, where shown, is based on the ultimate strength of the connection with a safety factor of 5.0, un-less otherwise noted.
Pipe Clamps In Special Materials (P1109, P1211, P1425, P2024 Series)
COPPER TUBING TYPE K OR LSTANDARD PIPE ORRIGID CONDUITEMT CONDUIT
UNICUSHION FEATURES
• Shock absorption • Protection from corrosion and abrasion • Allowance for expansion and contraction in pipe diameter • Sound and vibration isolation • Stability in use from - 50° F (-47° C) to + 350°F (+177° C) • Flexible elastomer material • Will not support combustion
* Maximum weight equals weight of rigid conduit plus weight of heaviest conductor combination (from the National Electrical Code Handbook.)
346-12. Supports. Rigid metal conduit shall be installed as a complete system as provided in Article 344 and shall be securely fastened in place. Conduit shall be firmly fastened within 3 feet (914.4 mm) of each outlet box, junction box, cabinet, or fitting. Conduit shall be sup-ported at least every 10 feet (3.05 m).
Exception: If made up with threaded couplings, it shall be permissible to support straight runs of rigid metal conduit in accordance with Table 344.30 (B)(2), provided such supports prevent transmission of stresses to termination where conduit is deflected between supports.
The above spacing based on a combined bending and shear stress of 1500 PSI when pipe is filled with water and the pitch of the line is such that a sag of 0.1 in. between supports is permissible.
