Clamp Together Duct is an industrial ducting system that uses an over-center clamp to join the rolled lipped ends formed onto the end of ALL duct components - pipe, elbow, branches, all fittings and specially fabricated parts. Further, the system is fully adjustable, utilizing the fact that a cut piece of pipe will slide into either the 11” adjustable sleeve or the end of any fitting. The pipe is then clamped to the sleeve or the fitting by using a rubber O-ring that secures the pipe to the fitting or sleeve as the clamp connects the two.
