I'm working on a house built in the early 80s that has a lot of damaged plastic electical boxes. The plastic box bosses that the outlet screws into have broken off so that the outlet cannot be secured.
In the past I have tried replacing the outlet boxes by cutting off the nails that attach the boxes to the stud by a hacksaw, removing them, and replacing them with new plastic boxes that have flip up tabs that secure the box to the drywall.
This does not really work that well because the boxes atill are not all that secure and they seem like like they could be pulled out by tripping over the cord that's plugged into them.
Is there a better solution?
