The AB40 Horizontal Adapter serves as a horizontal adapter for the MM340, MM540 and MM700 mounts, providing a 90-degree bridge between their wall plate and the TV mount lifting arm. This allows the wall plate to lay flat on a horizontal surface such as a large shelf or inside a recessed alcove.
Another application for the AB40 Horizontal Adapter Bracket is as a pass-through support for the when mounting the MM340, MM540’and MM700 mounts to thin brick facades or simulated stone panels made from foam, neither of which are strong enough to support the weight of a MantelMount.
NOTE: The AB40 also requires the purchase of the SSB40 Single Stud Adapter to provide the correct mounting holes if mounting an MM340 Standard Mount or the MM540 Enhanced Mount to a horizontal surface or stone/brick facade. The MM700 Pro mount attaches directly to the AB40 Horizontal Adapter Bracket and does not require the SSB40 adapter
