Rack Sentry protectors are extremely simple to install by one person, without tools. No need to drill into the floor or the rack upright to make this protection product work properly. Simply detach the hook-n-loop nylon strap, mount the correct-sized Rack Sentry protector and reattach the strap around the upright. The nylon straps are over-length in case of an obstruction behind the upright. It is that simple to obtain forklift damage protection for the workplace!
