4" Square Metal Box?

Hi all, long time!

Nice to see some familiar names too!

Simple trade question today, wanted to know off hand if anyone has seen a 4" square 2 1/8" deep square metal box without the ground bump? I know that its optional on the 1 1/2" deep model, but I am seeing specs for the 2 1/8" model that says it has it and some places have old stock photos (assuming). Preferably in welded version. Can anyone find a name or link me to a supplier?

I only need 1 for a specific application where depth is critical and the ground bump is in the way... Instead of having the lousy ground bump, they should have a tapping screw, so that it eats into the masonry when installed on those types of walls, otherwise I can see why they bothered!

Thanks in advance!

The bump makes it faster to install since a hole does not need to be drilled for the ground screw. A simple idea that should have been done years ago.

Ground screws that would drill into masonry would cost too much. Also the boxes are not always mounted on masonry. The masonry drilling screw would be useless on steel.

Nowadays even boxes without the bump still will have a threaded hole for a ground screw.

Also recently had discussion that some boxes used to have the bump but now don't. Same part number/bar code on them. So your best bet would be to visit suppliers and hardware stores to see it yourself.

True, pcboss, but don't most of the folks throwing boxes on steel studs use hanger bars now for speed of install?

Thanks Astuff, that is a good point, I will check into that.

There was a recent thread here on the same issue. I couldn't find it.

One point that was made was the welded boxes will have the raised ground while the stamped boxes do not.

I think I have seen stamped boxes with the raised bump.
