Place this easy-to-install protector around your building's exposed interior columns to save money on repairs, maintenance, and potential injuries and equipment damage. The bumper surrounds the column with a cushion of air, creating a safe zone around the column. The guard reduces chances of a collision because it's colored high-visibility yellow. It's lightweight and easy to move, store, install, or re-install. Easy to install: The column protectors are delivered with two sides and the attaching strap. Simply place the two sides around the column, wrap the nylon straps around the unit, and press the hook and loop fastener to the strap. It's built of a low density polyethylene (LLDPE) which is stress-crack resistant. Tough enough to take a walloping, it's got a wall thickness of .25" and is UL Listed as UL94 Flame Class.
