One person can slide heavy items across commercial carpet, wood, resilient flooring or smooth concrete. Molded of a slick, high density, low friction plastic, the slides are intentionally cupped to allow easiest movement by minimizing leading edge drag. Tough polyester fabric won't tear and is mounted to a foam pad that is guaranteed not to pull away from the slide in normal use. Easily stored in tool box. Safety Slides are great for easy moving of all types of furniture, especially modular office furniture panels, and other hard-to-move items like loaded file cabinets. These 6" diameter slides are sold four per set. Supplied with instructions.
