ALLIED MOULDED H9331-ESK Old Work Fiberglass Single Gang Electrical Box

This manufacturer makes several flavors of this product. The one sent to me had plastic clamps that were not actually installed on the box - they were just wedged in the box for user installation, unlike the product illustration. Add ten minutes or so to the time it takes to install each box.Also this box is not especially good for use in walls with plaster on wooden lath. The in-wall clamp and the outer plates that rest against the wall to not line up, so tightening the clamp torques the wall on different strips of lath and can easily damage a carefully cut hole. But this one is fine for gypsum board or wood wall finishes.

I had to open up an opening that had fit a blue plastic old work box. Height was OK. Width of the opening was too narrow. I trimmed the metal spring part with tin snips to accommodate paneling that was 1 1/4” thick.this box solved my need with a rugged, securely mounted box.

Well made box. Very sturdy. Mounted it in a wall that was 1 1/4 in thick so didn’t use mounting clip but used screws . Worked out great.

Great box for old work
