MantelMount Recess Box
Provides for 1.75” flush-to-wall mounting by allowing the center arm to fold into the recess box. For use with MM340, MM540 and MM700 mounts. This simple-to-install add-on accessory allows you to integrate MantelMount seamlessly into a custom-built wall opening. Easily fitting between standard or custom stud configurations, the RB100 provides the flush TV-to-wall storage  by allowing the MantelMount center arm to now fold into the wall opening when the TV is in the raised position. The result is concealed mounting hardware and a 1.75 inch flush-to wall TV storage!
A TV at least 32 inches in height should entirely conceal the recess box when in the raised position. For TV's shorter than 32 inches in height, you may see a portion of the recess box when the TV is raised.
