Shower switch back boxes

[maguire]

Hi all What are you guys using for 10mm cable into drywall boxes even using extra deep it's still a bit of a pain I have started to cut the knock out a bit bigger to allow the cables a bit more room on the push back any product out there I have not heard of

Similar to you, I tend to cut most of the back out of the single fastafix boxes.

Surely that makes them non-compliant?

Dress the conductors well and shape them then they will fit just right.
