I have a 4" square box (https://i.imgur.com/dFG6R3N.jpg) which I'm going to put a GFCI outlet in. I got one of the raised covers with a rectangular cutout for GFCIs but the outlet itself doesn't sit flush with the cover.

The cover looks like this: https://i.imgur.com/NOS6l2M.jpg but when I put it over the outlet, the screw holes at the top and bottom of the outlet stick out too far and prevents it from sitting flush. I know that I can remove the corner perforated tabs but there are still additional screw holes that stick out.

See circled in blue here:

Do I just bend the secondary screw holes back or something? Seems kind of weird because I've only read online about removing the tabs and not that second set of holes. The cover is made for GFCI outlets so why wouldn't it just fit?

 

You have to break or bend the tabs back, including the screw holes.

 

You will have to use separate nuts and bolts through the non-threaded holes to hold that device in the cover. As Ben stated, the ears and threaded hole sections need to be cut off or bent back.

 

Yup, just cut them off with linesman pliers or diagonal cutters. Tin snips also work in a pinch.

 

Just gave that a try and worked great. Thanks!
