This 1 1/2 inch Plenum Plus (R) no-hub coupling is a mechanical joint coupling for use in return air plenums. The 300 series stainless steel outer band and hand tool assembled clamp make this strong coupling easy to install. Coupling can also be removed after installation for project changes or maintenance requirements, and makes it easy to assemble complex sub-assemblies.
