Review on Arlington Non Metallic Box Extender 1 Gang: Enhancing Electrical Enclosures for Optimal Space by Kelvin Hernandez

Great product but watch out for adapter thickness. Really thought he called 3/8" but got 1/2". So far it's working well, it just sticks out more than it should. The unique position doesn't offer much clearance, it's so close that the door bangs against it when the switch is halfway between on and off. And yes, I know it would have to be done on purpose, but kids are kids.
