Customer Reviews

1-1/2 in. Foam Board Screw Clips (100-Pack) is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from great product I was concerned that these would not hold up to construction traffic and stay put in the foam but they hold really well. If you need to move them it is not hard and they do not damage the foam much. Apparently there is a long drill attachment you can use so that you don't have to bend over to attach them but in my experience I am usually bent over lining up the pipe with my hands anyway. Unless you do this for a living it would be hard to justify the price of something like an Uponor foam stapler. Installing radiant heat pipe just does not take that long. They do hold the pipe off where the clip is the foam a small amount like about an eighth of an inch . The concrete guy was nervous about the foam with the pipe floating to the surface somehow which he had heard happened to another contractor. Be sure and glue the foam down if possible and probably make sure the concrete can not get down under the foam at the joints. Mine was glued and we had no problems.
