thread easily and not pull out when tension is applied.
2) To determine proper screw length, insert thread depth indicator into a
threaded insert on the flat panel.
3) Mark the thread depth indicator 1/8” above the
depth of the threaded insert. (FIGURE P)
4) Select a screw that is shorter than the 1/8” mark
made on the thread depth indicator.
CAUTION! Do not use any screw longer than the 1/8”
mark or damage to the flat panel may occur.

Attaching Vertical Mounting Brackets to Flat Panel
NOTE: Be sure to observe the “up” arrow on each vertical
mounting bracket to maintain the proper orientation of the
flat panel. (FIGURE R)
1) Place the flat panel face down on a soft, flat surface and
identify the number and location of screws.
2) Align the holes on each vertical mounting bracket with the
threaded inserts on the flat panel.
3) Secure each vertical mounting bracket with the
screws and hardware identified in previous
steps. Use a minimum of (2) screws per vertical
mounting bracket.
Universal Washers
Universal washers are designed to accommodate
the various M4, M5, M6 and M8 hole sizes found in
flat panels.
NOTES:
• Place flat panel on soft, flat surface while working.
• Do not place excessive pressure on back of the flat
panel.
• Universal washers must be installed between
the head of the mounting screw and the
vertical mounting bracket as shown.
(FIGURE Q)
Nylon Spacers
Nylon spacers add distance between vertical mounting
bracket and flat panel. They will fit all supplied screw sizes.
The spacers must be used only when attaching flat panels
which have:
• Recessed mount points
• Uneven mount points
• Any obstruction near the mount points
• A curved back
NOTES:
• Nylon Spacers must be stacked and oriented as shown.
• Nylon Spacers must only be installed between the vertical
mounting bracket and the flat panel.

bracket and rotate locking clamps down.
(FIGURE S)
2) Raise the flat panel slightly above the top
and bottom rails on the horizontal mounting
bracket. (FIGURE S)
3) Slide the flat panel down slowly, ensuring
that the top hook on the vertical mounting
bracket properly engages the horizontal
mounting bracket. (FIGURE S)
4) Check for proper height.
(Remove and adjust height as necessary)
5) Rotate locking clamps up and insert
locking pins as shown. (FIGURE T)
6) Snap end caps into the top of both columns.
