One of the 110v outlet boxes in our home had a "sagging" faceplate. It turned out that the screws for the plate didn't have a traditional threads to screw into. Upon further investigation the box has two spots (top and bottom) for an unusual sized plastic-nut insert, a black plastic about 1cm W x 1cm H x 2.5 cm L with threads along the inside length of the piece.
What type of unusual outlet box is this? I'd like to find this replacement plastic piece so that I can position the faceplate correctly as the box itself is securely in place.
- We are in a townhome which is part of a larger hoa of similar homes so this piece may be proprietary based on some sort of contract with the developer
- Since finding this I've noticed problems with a couple other faceplates where these plastic pieces are also broken / stripped
** EDIT **
Here's a video of the box
