AUDAC WB50/FS Flush-Mount Box for AUDAC Wall Panels, Solid Wall

The WB50/FS is the masonry back box for AUDAC wall panels. It is pressed in galvanised steel rather than moulded in ABS, because a box chased into brick or block is going to be handled by a trowel and then buried in filler.

The cut-out matches the hollow-wall WB50/FG at 5.31 x 2.95 inches, so a panel schedule works across both wall types. The box itself is 5.24 x 2.83 x 1.85 inches, slightly shallower than the ABS version.
