The mounting bracket work as advertised. However, i find the ones from amazon to fit better as the corner plastic pieces are slanted (doesn't hit anything as it's installed into a cavity where there's somebehind the corner pieces). These ones from prime cable are does not have the slanted pieces which makes it hit whatever is behind the bracket.

Installation within drywall was quick and easy. The template spots and instructions were helpful. Be careful of the length of the screws used as sharp ends can be exposed, potentially damaging cables.

They’re very good material and fitted

Un peu plus ''mou'' que d'autres modèles, mais font amplement la job de tenir la plaque au mur.

I like these gang mounting brackets. They work well with the drywall even when it is crumbling.

They’re solid overall except the corners. Would have been better with something that holds all 4 corners except of 2.
