Assemble the vertical legs and horizontal beam from the H800 Heckler AV Wall structure and anchor the structure to the wall.
Refer to the H800 Heckler AV Wall guide for detailed assembly instructions.

Display-locking bumpers firmly hold your display to the crossbar during a seismic event. Therefore, it is important to position them correctly to enable the display-mounting rails to clasp the display-locking bumpers. Two display-locking bumpers are pre-installed to the XL display crossbar. The bumpers are pre-installed for VESA 350 compatibility.
Measure the horizontal spacing of your display’s mounting holes. Fasten the display-mounting bumpers to the positions on the crossbar that match your display’s horizontal mounting positions.

Install the XL display crossbar to the main structure by sliding the posts on the back of the bar into the vertical slot located at the top corners of the structure.

How far above the finished floor (AFF) do you want the bottom edge of your display? Take into account several factors such as the desired position of the video camera lens, display size, and a comfortable screen viewing angle. In general, we recommend positioning the center of your camera lens about 44 inches to 46 inches AFF. Then position the bottom edge of your display about one inch above the body of the camera.
Consider if camera movement will cause the camera to strike the display. For example, the hibernation position of a Logitech Rally Camera requires two additional inches of clearance between the display and the camera.
Place masking tape on the wall at the height where you would like to position the bottom edge of your display. Measure the distance between the tape and the top edge of the XL Display crossbar.

The bumper brackets provide support between the wall and the lower rear surface of your display to help ensure a vertical display angle.
Hold the bumper bracket as a handle.
Align the left and right bumps to the holes on the end of the display rail (included in the H800 Heckler AV Wall structure).
Gently squeeze the middle bridge of the bumper bracket.
Insert the bumper bracket into the display rail and ensure the bumps engage with the holes on the display rail.

The mounting height of the display is determined by the installation position of the display rail relative to your display.
With your display standing in its packaging or leaning against a wall, use a tape measure to measure up from the bottom edge of the display.
Place masking tape on the back of your display at measurement X . You noted this measurement in the previous step.
Position a display rail (included in the H800 Heckler AV Wall base) against your display so that the cork liner on the rail hook aligns with measurement X .
If you cannot position the hook at measurement X while aligning to both the lower and upper mounting holes on the display, move the hook’s installation position relative to the display rail. To do so, remove the nuts holding the hook part to the rail, then move the hook to the high or low hook mounting position, then fasten the hook back in place.
From the provided set of display-mounting screws, select the correct length and size of screws for your display’s mounting holes, and fasten each display rail to your display.
Refer to your display manufacturer’s instructions for the proper screw size and depth to be used with your display.

Two or more people are required to safely hang the display. Extremely large displays should be hung with the assistance of lifting equipment.
Connect the HDMI and power cable to the display.
Carefully lift the display and move close to the structure.
Before lowering the display onto the XL Display crossbar, align the display hooks to the left of the display-locking bumpers.
Lower the display onto the crossbar so that the hooks do not touch the display-locking bumpers. Rest the cork-lined surface of the hooks directly and firmly on the crossbar.
Slide the display to the right, towards the center of the structure until the display is centered on the structure. You will feel the rubber bumpers engage with the hooks.

In geographic areas with high seismic activity, and in areas prone to convenience theft, you may wish to add additional protection to lock your displays to the structure.
Use a step stool or ladder, and lower the provided wood rod into a hole on the top surface of the XL display crossbar, directly behind a display hook location.
The presence of the rod prevents the display hook from backing away from the display-locking bumper.
If a portion of the dowel is visible above your display, cut the rod to an appropriate length and reinstall the rod.

Use the cable guides (included in the H800 Heckler AV Wall base) to organize the cables inside the vertical legs.
