Notes:

Design loads apply only to Unistrut brand products. Look for “UNISTRUT” on the part.

For use with non-seismic loads. Based on static testing in 12 ga. channel with a safety factor of 5.0.

For use with seismic loads supporting Schdule EMT or IMC Conduit. Based on FM1950-10 dynamic testing in 12 ga. channel with a safety factor of 1.5. For conduit sizes larger than 2″, see the P1109 thru P1126 series clamps.
