Standard wall plate for keystones. I have some from here and some from monoprice, which are the same thing and which I got years ago. They have held up well, though I have one that is in my kitchen that has yellowed a bit over a course of about 8 years or so, though others have held up better - so I suspect that it may be a bit of ultraviolet deterioration from the natural light the plate gets in the kitchen.

Good

Great Wall plates, I have used them for many years and never a problem

well spaced and keystone jacks snaps right in.

Perfect and much cheaper than buying from other retailers.

great value
