2. Attach the two remaining sign brackets to a metal post, wall, ceiling, or
other surface with sufficient weight bearing rating. It is preferable that
you install the display on metal posts attached directly to studs. Never
install the brackets only on sheetrock with toggle bolts.
If installing directly onto a wall or ceiling, use two 5/16-inch lug
•
bolts and washers per bracket, screwed at least one inch into the
center of wood studs. The washer must be snug against the
bracket. The bracket must be snug against the sheetrock or other
wall surface.
If a wooden stud is not available in the correct spot, use 3/4-inch
•
thick plywood or a 3/4-inch metal backing plate attached to studs
to secure the bracket.
3. Ensure the wall brackets align with the brackets on the sign.
4. Attach the mounting brackets on each end of the sign to each other as
shown below:
5. Use 2, 5/16-18×3/4-in Phillips screws (C), and the 2, 5/16 lock washers
(D) through the mounting holes as shown below. Secure with the 2, 5/16-
18 nuts (E).
6. DO NOT tighten the nuts at this time.
7. Match the alignment holes of the brackets on the sign with the holes of
the brackets on the wall so that the sign is at the desired viewing angle.
8. Fasten the mounting brackets together using the 4, 10-32×3/4-inch
Phillips screws (F), the four #10 lock washers (G), and the 4 10-32 lock
nuts (H) through the selected alignment holes on each end of the sign.
9. Tighten to 2.71 N-m (24.00 in-lb).
