Power and low voltage wiring behind even flat mounted television panels is now easy with the Strong™ SM-RBX-WH, a recessed back box that installs like an in-wall speaker and is super flexible for configuring options. Made of fireproof ABS plastic, it sits nearly flush off the wall so it will fit easily behind any mount. Need electricity, Powerlink, HDMI, Component? No Problem! There's plenty of room for wire management with this easy-to-install box. Unique in design, the SM-RBX-WH sits only 2.9mm off the wall. Why is this important? Simple…check out the Razor mount. This HAD to fit behind it because there isn't much else that will…at least not that you need for installs. If it fits behind this mount, you know it'll be a great compliment for other mounts, too. One of the simplest features is that no template is needed. Pin-holes were designed into the plate at four corners to easily allow you to place a dot on the wall, then draw.
