Used in conjunction with the MM340 Standard Mount, the MM540 Enhanced Mount and the RB100 Recess Box, the SSB40 serves as a direct replacement for their included wall plate when it can't reach your existing stud placement. Customers with a single stud centered in the intended mounting area can attach the SSB40 to your MantelMounts lifting arm the same as the wall plate, but the adapter has mounting hole configurations specifically for these single stud installations, as well as installations to large posts or beams (common with outdoor patio installations).
