Great solution for adding a wallplate
Crutchfield Customer Review (What's this?)
This is a great solution for installing a wallplate in an existing gypsum board wall. Note the hole for this bracket is not square. Hight is not same as width. Measure both hight and width before cutting your wall. If you cut the hole just right to make a tight fit this bracket will be very sturdy. If you make the hole too big, the bracket will be flimsy.
Pros: Great for adding a wallplate to an existing gypsum board wall. Very sturdy if installed correctly.
