Fantastic part! Really works well. This is a mounting clamp for 1/2" pipe. Works great for attaching 1/2" pvc pipe (Sch 40, Class 200, 315, etc) to a wall or eve or anything else. They have nail holes in them, and you can just nail it in place, but a better system is using stainless truss screws. To layout you system, just snap a chalk line, line up the 2 holes in the mounting clamp to the line, run in your two screws (or nails) and repeat. After you mount them (about every 3 or 4 feet) you just snap in your 1/2" pipe. Works like a dream. :)
If you are using screws, it will be easier if you drill out the holes in the mounting tabs.
