DESCRIPTION

The MR4050 is a heavy-duty ceiling/wall monitor mount designed to support up to 150 pounds
(68 kg). It fits monitors from 19 to 31 inches (49 to 79 cm) wide.

INSTALLATION

Monitor Assembly

Refer to Figure 1.

Monitor With Removable Feet

Remove the rubber feet from the monitor and
install the monitor adjustment brackets in their
place, using the original hardware. The monitor
adjustment brackets are reversible, but both
brackets should be attached with the flat side
facing in or out.

Monitor Without Removable Feet

Decide where you will attach the monitor ad­justment brackets. Attach the monitor adjust­ment brackets to your monitor using your own
mounting screws (not provided). The monitor
adjustment brackets are reversible, but both
brackets should be attached with the flat side
facing in or out.

Refer to Figure 2.

1. Measure the height and width of the monitor. Place the pan end brackets on their sides with
the bottom ends facing you. Separate the pan end brackets the measured width of the
monitor.

2. Attach the L-brackets to the studs on the pan brackets with the four flat washers, lock wash­ers, and 10-32 acorn nuts.

3. Place the monitor in the assembly to be sure the monitor fits correctly. Adjust the pan end
brackets if necessary .

4. Place the pan end bracket assembly on its side with the top end towards you.

5. Fit the top bar weld assembly and the two side arm top weld assemblies together.

6. Position the side arm top weld assemblies against the outside of the pan end brackets.

7. Fasten the side arms to the top bar by inserting four 1/4-20 x .625-inch bolts from the bot­tom of the top bar weld assembly. Attach flat washers, lock washers, and nuts inside the top
bar weld assembly and tighten.

8. Adjust each side arm equally, allo wing for the height of the monitor.

9. Align the top bracket assembly until one of the 1/2-inch bolt holes in the left side arm aligns
with a 1/2-inch hole in the left pan end bracket.

10. Fasten the left pan end bracket to the left, top bracket assembly with the 1/2-13 x 0.75-inch
bolt and washer and tighten. Repeat the procedure with the right side.

11. Adjust the mount to align the center angle adjustment hole in the left arm with the center
angle adjustment hole in the pan end bracket. Fasten a 1/4-20 x .625-inch bolt and washer.
Do not completely tighten. This bolt will be used later to lock the monitor at an angle. Re­peat the procedure with the right side.

12. Place the assembly upright on your work surface.

13. Thread the mounting pipe into the opening located in the middle of the top bar. Locate the
hole, see

Figure 2, in the side of the top bar weld assembly. Tighten the 8-32 Phillips

➀

screw, already located in the bar, to lock the mounting pipe into place.

14. Attach each side strap bracket to a pan end bracket with a 10-32 x .5-inch cap screw, lock
washer, washer, and acorn nut. Do not completely tighten. Repeat the procedure with the
right side.

STRAPPING

Mounting the Hanger Assembly

1. Determine the mounting location. Install ceiling or wall mount by following the instructions
that are provided with the mount and then proceed to step 2. Make sure the mount can sup­port four times its maximum specified load.

2. Thread the MR4050 mounting pipe into the ceiling or wall mount. Stop at the desired posi­tion after the threads have become tight (approximately 30 ft-lbs).

Monitor Mounting

1. Place the monitor in the mount.

2. Align the threaded inserts in the monitor adjustment brackets with the slots in the bottom of
the pan end brackets.

3. Secure the monitor to the pan end brackets with the four 10-32 x .5-inch socket head cap
screws, lock washers, and washers and tighten.

4. Be sure the .5-inch bolts holding the pan end brackets to the side arms

are firm enough so that the pan end bracket assembly will not tilt or fall
while the monitor angle is adjusted. To set the monitor angle remove the left 1/4-20

x .625-inch hex bolt and washer. Hold on to the monitor while removing the right 1/4-20 x
.625-inch hex bolt and washer. Tilt the monitor to the desired angle. Fasten the right pan
end bracket to the right side arm top weld assembly with the 1/4-20 x .625-inch hex bolt and
washer and tighten. Repeat with the left side.
