As opposed to one-hole strap clamps, this Two Hole Strap has two holes for a more snug fit. It mounts to a surface and holds the pipe or conduit in place by being screwed through both holes. When mounting conduit to a wall or other support structure, it is done so securely. It is appropriate for usage in both residential and commercial settings since its Two Hole Strap can handle pipes up to the diameter of copper tubes in both horizontal and vertical applications.
