Five-gang box extension


I'm going to be putting a five-gang electrical box in a wall that's going to be covered with a 1-1/4" granite backsplash.

Does somebody make an extension for a five-device box, or do I need to put the receptacle/switch tabs directly on the granite and use longer screws?

The maximum setback allowed with a non-combustible material like granite is 1/4". You will need to use box extenders. Arlington makes ones called BE-1 and BE-2 that are gangable.

Great! Amazon sells a five-pack for eleven bucks. That should do the trick.
