One-hole strap is a simple, U-shaped fastener used to secure conduit or pipe to a surface. It is constructed from a strip of zinc-plated steel, typically with a single, centered mounting hole.
Its primary function is to loop around a conduit and be anchored with a screw or bolt, holding it firmly against a wall, ceiling, or beam. This provides essential support, prevents sagging, and organizes runs.
Compared to two-hole straps, a one-hole strap offers quicker installation and is ideal for lighter-duty applications or where minimal hardware is preferred, though it provides less resistance to twisting.
