RC-Max is manufactured from 0.0190 50 KSI steel for additional strength. It has 1-1/2 wide screw flange, 2-7/16 overall width. RC-Max is used as a furring over wood or steel framed walls and ceilings. The reduced contact RC-Max affords with the supporting member offers economical means for controlling sound transmission. For walls, resilient furring channels should be installed with the mounting flange down, except at the starter row where the mounting flange may be installed with the flange up.
