Step 1 Mounting the Wall Plate to the Wall

Brick, Solid Concrete and Concrete Block Mounting:

Use the Wall Plate (part a) as a template to mark 6 hole locations on the wall. Three in the top row of slots and three more in the
bottom row. Make sure these holes are level and there is at least 8” distance between any two holes. Pre-Drill these holes with a
10mm masonry bit to at least 90mm in depth. I nsert a Concrete Anchor (part f) into each of these holes. Make sure the anchor is
seated completely flush with the concrete surface even if there is a layer of drywall or the other material in front. Attach the Wall Plate
to the wall using 6 Lag Bolts (part e) and 6 Lag Bolt Washers (part d), as shown in Diagram 1-B.

Wood Stud mounting:

The Wall Plate (part a) MUST be mounted to two wood studs. Use a stud finder to locate two adjacent studs. It is a good idea to verify

where the studs are located with an awl or thin nail as shown in Diagram 1-A. Pre-drill a 80mm deep hole at the desired height in each
stud using a 6mm
template to mark the location of the second hole in each stud. Drill pilot holes at each of the marked locations. Attach the Wall Plate to
the wall using the 4 Lag Bolts (part e) and 4 Lag Bolt Washers (part d).

Step 2 Mounting the TV Rails to the back of your Flat Panel TV

bolts are included. If other sizes are required, they are available at your local hardware store.

Before hanging the television, tighten the wing nuts on both TV rails so that the mechanism does not move during

Make sure the TV Rails (parts b & c) are mounted at an equal distance from the top of the TV and as close to the center as possible as
shown in diagram 2-A. The safety latches on the bottom of the arms should face outward from the television and the wing nuts should
point toward the top.. M4, M5 and M8
Plastic Spacers (part l) are provided for use with M4 and M5 screws. Use these spacers for televisions with curved or recessed back

panels as shown in diagram 2-B. For flat back panels, no spacers are necessary as shown in diagram 2-C. Make sure you are using
the correct bolt size for your television. Some televisions have shallow threaded inserts. 4 extra spacers have been included to
offset shallow mounting holes if the bolts provided are too long. Never force a bolt in deeper than the mounting holes allow. Doing

so may damage your television. At the same time, make sure that the bolt tip is sunk deep enough into each hole to support the
television.
installation.

Step 3 Hang the TV onto the Wall Plate

Warning: Some TVs may require two people to lift! Monoprice is not responsible for personal injury or product damage.

First hook the Monitor Bracket (parts b & c) over the top of the wall plate (part a). Then, let the bottom of the monitor brackets rotated
to the bottom of the wall plate as shown in Diagram 3-A. Slide up the safety latches on the bottom of each rail so that it engages the
bottom lip of the wall plate and tighten the safety screws to lock the latch in place. Finally, loosen the wing nuts on the top of each rail
to freely adjust the tilt angle of your television. Once the desired position is determined, tighten the wing nut to hold the television in
position as shown in diagram 3-B.

Congratulations! You’re Finished.
