BUD Industries JB-3954-KO Steel NEMA 1 Sheet Metal Junction Box with Knockout and Lift-off Screw Cover, 6" Width x 6" Height x 3" Depth, Gray Finish

Very helpful to find this quality product at a reasonable price.

Bought something at a local supplier, this is much better.

Sturdy box for the money paid

I used this box while wiring my house for ethernet (to cover the wires going into the wall from the patch panel). It's extremely sturdy, and with a little modification, worked perfectly. I had to drill a 2.25" hole into the back (since there were no knockouts on the. side opposite the open side, which is a downside), but other than that, no complaints - I don't expect I'll ever have to replace this.

The box is heavily constructed and the cover plate actually fits on the box! The screws are not of the usual low quality such as I often find on load centers, regardless of brand. The knockouts are a bit tough to remove but I guess that is due to the metal gauge. Very nice box and very reasonable in cost. Be aware it does not offer a knockout in the back if you intended that to be so.
