Unlike traditional metal trims, SNAD® is a plastic adhesive snap component. This product will not snag clothing or deteriorate from exposure to sunlight, sand, or dirt. Plus, walking on SNAD® is pain free due to its unique dome shape. Installation is simple, clean the surface where the snap is to be applied, peel off the protective paper backing, position and firmly hold the snap in place and release. No tools, no waiting, no splits, no holes!
