mounting system is level.
3)
Mark the centers of two slots in the top and bottom
wall plate arms with a pencil. Be careful not to mark a
mortar joint. With your electrical drill and 1/2" masonry
bit, pre-drill a 3" deep hole at each mark.
4)
Install the supplied plastic anchors in each hole.
Tap into holes until fully seated.
5)
Attach the wall plate arms to the wall using the
supplied lag bolts and round washers, as shown
to the right.
6) Attach the wall plate arm's quick-snap bolt covers
to conceal the installed lag bolts.
DO NOT over tighten bolts. This can damage
the wall plate or the surface of your wall.
DO NOT release the wall plate until you
are absolutely sure it is secured to the wall.
