Question: What is a Kee Klamp structural pipe fitting?
Answer: Kee Klamp slip-on pipe fittings are malleable cast-iron pipe fittings, which conform to ASTM A47-77-32510. Kee Klamp fittings are used in conjunction with steel pipe to build structures of unlimited size and scope. Casehardened setscrews attach the fittings securely around the pipe or tube. There is no welding, drilling, or bolting required when building with Kee Klamp fittings. Kee Klamp fittings are galvanized, making them ideal for indoor or outdoor use. The only tools required for building Kee Klamp structures are a pipe cutter and a standard hex key.
