I was told to buy a "belt clip" to help me build an RC boat from a set of pieces of wood I had. I had never heard of one so I stumbled across Revain to find it. I found this one which seemed to fill the bill for what I needed. The delivery was fast and the product seemed quite well made. It was easy to use and had enough tape length to handle a number of projects in my opinion. I used it to attach the main hull to an RC boat I was building. Wow. Who cares what this product did when assembled! This was the second set I've made and the first time I had to measure a square with a triangle and hope all the other pieces were really square. As for the belt clip, I just spliced it on the ends with 30 minute epoxy, adjusted the clip to hold things as they should, tightened it so it was snug (but not very tight) and let the case sit . It came out with PERFECT right angles of 90 degrees. I'm very glad I got this. This greatly simplified and improved the project. Highly recommended!
