MPC’s extended clamp (GS) was specially developed for smoke flues, e.g. for steel and stainless steel chimneys. This is why the GS is also known as chimney clamp. With one weld and the tightening of one bolt, the smoke gases have no chance to leak.
For ventilation systems, MPC developed the Easy Fit (EF) clamps, which are ideal for flexible and semi-rigid round diameter ducts. The rigid ducts and pipes are held in place by our duct clamps (MPC SL and DL). MPC wormdrive clamps can also be found in ventilation ducts.
