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.

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.
