EMT conduit strap for 3-1/2 in pipe

This one-hole strap secures EMT conduit or rigid pipe in electrical installations. It is made from steel with a zinc finish for corrosion resistance. The part suits contractors and maintenance teams running 3-1/2 in conduit on walls or structural members.

Simple single-screw mounting

The strap fastens with one screw or bolt through the pre-drilled hole, so alignment is straightforward. Common issues include using a fastener that is too short for the mounting surface or over-tightening, which can deform the strap and reduce grip on the conduit.

Check conduit size and surface before ordering

Verify that the conduit outside diameter matches the 3-1/2 in trade size this strap is designed for. Confirm the mounting surface can accept the required fastener type and that the zinc finish suits the environment, especially if exposure to moisture or chemicals is expected.
