AUDAC WB3102/FG Flush-Mount Wall Box for VC3xx2, Hollow Wall

The WB3102/FG is the dry-lining back box for AUDAC's VC3xx2 volume controllers. It goes into plasterboard or a stud partition through a cut-out and grips the board from behind, so the controller sits flush without needing anything solid to screw into.

This is the hollow-wall version. For masonry, specify the WB3102/FS instead; the two are not interchangeable once the wall is closed up.
