Rated 2 out of 5 by from MK grid frame A reasonable replacement for the much earlier frame but rather fiddly to assemble and necessary to connect wiring to switches before putting whole assembly into back box.

Rated 5 out of 5 by from Looks Good but Fiddly I had the same issue as other reviewers with the screws being too short. Had to destroy the captive retaing washers to fit longer screws. Replaced an old MK unit with 3 gang switching in a 2 gang backbox. Finished result looks good.

Rated 3 out of 5 by from It works ok, but... Like Beazer, I had to destroy the existing screws and use longer ones to attach the frame to a 25mm back box, that had been tiled over. The frame is stronger than the one it replaced.

Rated 4 out of 5 by from Solid, but must prewire switch Nicely made, and makes the possibility of a grid switch to match other MK stuff work, so has to be good on that alone! One slight annoyance is that the terminal screws are covered by the frame when the switch is inserted. This means the terminals have to be tightened with switches separate, and when linked with 2.5mm cable it can be a struggle to get them in. Would still buy again, but MK could do with moving screws on 20A switch backward or making the frame a little thinner so screws can be accessed with it assembled. Another tiny annoyance is the captive screws to fit to the back box; if they are too short because the box is set too far back it takes a couple of minutes to destroy the captive washers to get the screws out to fit something longer.
