Masonry Mounting

Masonry mounting requires specialized knowledge, skills and tools. Monster highly recommends that you seek the help of a professional installer when mounting to masonry.

1)With the help of a friend, position the mounting system in your desired mounting location.

2)	�����	Using the provided level, confirm that the
	�����

system’s wall plate arms are 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" (12.7mm) masonry bit, pre-drill a 3" (76.2mm) deep hole at each mark.

4)Install the supplied plastic anchors in each hole. Tap into holes until fully seated.

5)Attach the top wall plate arm to the wall using one of the supplied lag bolts and washers, as shown to the right.

6)Next, place the power unit mounting plate over the mounting holes on the bottom wall plate arm. Secure it with the other supplied lag bolt and washer.

7)Tighten each bolt with your electric drill or socket wrench.

DO NOT over tighten bolts. This can damage

the wall plate or the surface of your wall.
