I am getting very frustrated with the Scholmore metal dry lining back boxes. They look great in the blurb but I have either got a bad batch or something is fundamentally wrong with the design.
They are difficult to fit as the spring mechanism that holds lugs is almost always dysfunctional, slides out of its guide at the bottom & tilts over so takes a lot of fiddling to get it to grip and fitting the face plate involves even more fiddling. Maybe I am missing something but I cannot see what.
So I am looking for alternative solutions to fire protection in drywall back boxes. I have found these inserts:
From Astroflame which look can work with both plastic and metal back boxes so I can use the standard plastic back boxes and fit these things although, to be honest, they also look a bit clunky - does anyone have an experience of these inserts or perhaps a better solution all round to the problem.
