2pc Banana Plug Binding Post Inset Wall Plate very impressed
Well constructed, I Was impressed I've seen others that cost much more than these, they served my purpose. Bought 2 for a extra one. Fits in my application really well, the location was to close to my unit to use the banana plugs so I used the bare wire. I would recommend this product. Beginner to pro's.
It wasn't clear in the description but you can screw these direct to the wall without a mounting bracket/box. There's 4 holes you can put your own screws in and then the faceplate screws into its holes. If you do put this on a wall box, cut off the little spacer legs on back of the faceplate so that it sits flush against the wall.
Bought 2 of these wall plates to interconnect my rear surround speakers to the AVR, which is on opposing wall. Ran some CL-2 cables between these 2 plates behind the walls, and connect to the AVR and speakers at their respective wall plates. Now everything looks clean and hidden, and my wife likes it too.
