Missing grommets

[mrloy99]

I agree, however, i have seen many installations where they have not been used and they have all been ok, but i have seen some that are not, mainly due to three t&e's in a back box, which makes it more tricky to get the faceplate back, but i do understand what you are saying.

Another one of those fab grey areas that we all love.

Indeed. Maybe if the manufactors of metal back boxes gave us the option of a suitable 25mm oval knockout it would make things easier. Though I only use round conduit myself.
