RACO 232 4 in. Square Electrical Box, 2-1/8-Inch Deep, 1/2-in. and 3/4-in. Side Knockouts, Welded, Gray, 25-Pack

good box. it has them combination ko's and the raised hub for ground. it is also the deep version.

Great quality box and perfect for my needs.

strong construction , no issues

Great price, but does not come with a ground screw

Works as it should

Does what it should. I bought a cover and the side clamps to use as a junction box.

In lots of boxes like this you can't knock out the smaller half-inch knockouts without risking knocking out the larger three-quarters knockout. I had no trouble getting the half-inch one out, and the three-quarters stayed pretty strongly attached. The dimple for the ground lug made it easy to use the conduit for equipment ground. Also appreciated the pre-drilled holes for mounting. The holes are pretty far apart on the top and bottom so you can get a good anchor into a stud with plenty of leverage.

I am using these boxes while upgrading my basement.
