PERMALIGHT® foamy bumper guards, made of recyclable polyurethane foam, have an alerting daylight-color yellow with black contrast stripes. These brightly daytime-visible bumpers help prevent employees from getting injured by bumping into protruding corners, obstacles, sharp edges and other objects that could cause expensive workers compensation claims. They also help prevent damages to equipment and building interior. The 39-3/8" long strips come in 7 shapes. Three of those are also photoluminescent and glow in the dark during a power failure. Simply remove the protective silicone liner and press-apply the sturdy adhesive-backed strips to I-beam shelves, metal, walls, wood and other clean surfaces.
