The VisionMount LR1A recessed in-wall box allows a flat-panel TV to rest flush against the wall, hiding mounting hardware for a "no profile" solution for full-motion mounts. Easily installed by cutting a hole into sheetrock between wood studs. Finger-adjustable Quick Shims allow box to be leveled and secured tightly into place. Heavy-gauge steel construction is available in black, silver or paintable white finish. Bottom of box features knockouts for 110-Volt outlet and power cables. Supports VisionMount VM400, LRF118 and MF215 wall mounts to hold virtually any flat panel TV from 15" - 50". When used with the LR1A, mounts have an offset of 4.6" to the left of center.
