Mounting the fixture on a truss
The fixture can be clamped to a truss or similar rigging structure in any orientation. When installing the
fixture hanging vertically down, you can use an open-type clamp such as a G-clamp. When installing in
any other orientation, you must use a half-coupler clamp that completely encircles the truss chord.
To clamp the fixture to a truss:
1.
Check that the rigging structure can support at least 10 times the weight of all fixtures and equipment
to be installed on it.
2. Block access under the work area.
3. Fold the legs of the mounting bracket together and bolt a rigging clamp securely to the mounting
bracket. The bolt used must be M10, grade 8.8 steel minimum. It must pass through both mounting
bracket legs and be fastened with a self-locking nut.
4.
Working from a stable platform, hang the fixture with its clamp on the truss and fasten the clamp se
-
curely.
5.
Secure the fixture with a safety cable as directed below.
Securing with a safety cable
Secure the fixture with a safety cable (or other secondary attachment) that is approved for the weight of
the fixture so that the safety cable will hold the fixture if a primary attachment fails.
Loop the safety cable through the eyebolt in the back of the fixture and around a secure anchoring point.
Do not loop the safety cable around the fixture’s mounting bracket only, as this will leave the fixture un
-
secured if it separates from the bracket.
