Review on 🔌 Madison Electric Products MSB3G Adjustable: Enhancing Electrical Flexibility with Ease by Bruce Marable

The box is inherently so wide and not very rigid that it wobbles a bit and needs a panel to stabilize it on the wall. It works well but a stiffer box would be better. Also, the impact wrench is the only screwdriver that seems to effectively drive screws in all the way without removing the head. The narrowness of the screw holes in the box makes it difficult to get the screws in, and also makes it difficult to get the box flush with the wall because it will want to back off in the angle of the screws. It is best to lift the box just a hair and then tighten the screws. If you can somehow attach it prior to installation that would be ideal.
