Figure 22: Tightening the rail kit to the backbox
Suspending the C12BB3 Backbox
The C12BB3 backbox will generally be installed in tile-based ceiling systems, but can also be installed in
open space. Use eyebolt kits (part number 1/4EYBLTKIT) to fasten conventional rigging hardware to the
C12BB3.
NOTE: There are several 1/4-20 suspension points located in the back panel of the
C12BB3. These can be used as alternate support and rigging points for open ceiling plan
installation. Community recommends all mounting and rigging methods be approved by a
qualified Professional Engineer.
Required Tool:
• Stiff screwdriver (or similar tool) for snugging eyebolts
Instructions for suspending the backbox using eyebolts:
1. Unpack the 1/4EYBLTKIT and find the following items:
a. (4) 1/4” Forged Shouldered Eyebolts
b. (4) Cup Washers
2. Set aside (4) cup washers as they are not used for this application.
3. Insert one eyebolt kit in each suspension point and turn it until seated snug on the rear of the
cabinet surface.
4. Do not over-tighten the eyebolt. Once seated, the eyebolt will only need 1/8-turn to ¼-turn to
firmly tighten. Insert a stiff tool through the eye to help “snug” the eyebolt into position, but do not
use that as a tightening (or “torquing”) tool.
5. In some cases shims (not included) will be necessary to adjust the orientation of the eyebolt so that
the plane of the eye correctly aligns with the direction of the attached suspension cable.
6. The eyebolts should be installed tight enough to prevent accidental unfastening, but not tight
enough to damage the insert threads.
