RACO 786B – Frequently Asked Questions
1) What does the RACO 786B BLOCK-LOC tile cover actually do on a block wall rough-in?
The 786B is a 4 inch square tile cover, 2 inch deep, that finishes a 1-gang device opening in tile-faced or masonry block walls. It seats into the finished wall opening over the box so the device sits flush with the tile face instead of recessed behind it. It is a cover, not a box, so you still need the 4 inch square box behind it.
2) Will the 786B cover a two-gang device opening?
No. The 786B is a 1-gang cover only, sized to finish a single device opening. For a two-gang opening in tile or block you need a 2-gang cover from the BLOCK-LOC family instead.
3) Does the RACO 786B come with a mounting bracket?
No bracket is supplied with the 786B. It is a no-bracket configuration, intended for tile-in and block-wall work where the cover seats directly into the wall opening rather than being bracket-mounted to a stud. If you are framing into steel or wood studs and need a bracketed assembly, this is not the part.
4) Is the 786B tile cover welded or drawn, and does that matter for install?
Welded, one-piece construction. For a 2 inch deep tile cover that gets handled and tapped into a masonry opening, a welded body keeps its shape rather than flexing out of square, which matters when the device plate has to sit flat on the tile.
5) What part number and manufacturer should I give my distributor for this RACO tile cover?
Order it as RACO 786B, part of the BLOCK-LOC Series. RACO is a Hubbell brand, and the manufacturer part number is simply 786B.
