Really cool! Ensures a nice, clean and clear gas supply for my new gas dryer on the go! Cut a hole for the back box in the wrong place, which could interfere with the vent hose (check the unit's specs after cutting the hole. Yes!), but cut on the other side of the stud and repair the first hole . .we are not ready to go! Worth every penny for avoiding drilling a hole in the floor while also providing another exit point for any water spillage alongside the existing downstairs drain.
