Description

This baseplate is used for the adjustable mount in tight areas and has a 3 4 wide extension piece that can vary in extension distance measured from the underside of the mount   

This  can be installed in narrow areas that are 3 4in wide where you can fit a swivel base and let it overhang on side.   The screw holes are offset 1 2in from the edge.  So if you can install the screw at least 1 2in off the wall and the area is flat, then this adapter plate will fit.
