Description of Leviton T5015 I 15 Amp 125 Volt Receptacle
Large-head terminal screws, backed out and staked, accept No. 10 copper or copper-clad wire. Heavy-Duty brass power contacts for maximum conductivity and plug retention. Shallow design for maximum wiring room in box. Convenient washer-type break-off plaster ears for best flush alignment. Captive mounting screws for fast installation where applicable.
Works well, this is Leviton. Slightly larger than the base, there is a small gap around the perimeter of the circle. It just looks a little bad. I'm not sure what size the circle should be, I don't know of any other size wall panel.
