Non Metallic, Corrosive Resistant Pipe Clamp Kwik Block is a plastic fastening system made from a very strong high density copolymer polypropylene. It is virtually impervious to water, UV rays, and chemicals. Because it can be fastened to most any surface by use of nails, screws, or adhesives, it is used in electrical environments, food service establishments, HVAC & refrigeration, agricultural and farming, solar installations, and equipment manufacturing (OEM's). By combining a Kwik Block with a any tether you the load will be secured to support most sizes of piping, wiring, and other products presently on the market.
