Fastening the fixture to a flat surface
Use a stable horizontal surface that can support at least 10 times the weight
of all the fixtures and equipment that it will support. Ensure that all fasteners
used can support at least ten times the weight of all the fixtures and
equipment that they will support.
To fasten the fixture to a surface:
1. See illustration on left. Pass an M12,
grade 8.8 steel minimum, bolt or
screwbolt through the hole (arrowed) in
the center of the main mounting
bracket leg and into the surface.
2. If using a bolt, secure with a washer
and self-locking nut.
3. Check that the fixture is held securely.
4. If you install the fixture in a location
where it may cause injury or damage if
it falls, secure it as directed below with
a securely anchored safety cable that
will hold the fixture if the primary
fastening method fails.
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 (see
illustration on right) that completely encircles the truss
chord.
To clamp the fixture to a truss:
1. Check that the rigging structure can support at least ten times the weight
of all fixtures and equipment to be installed on it.
2. Block access under the work area.
3. Either:
-
Bolt a rigging clamp directly to the fixture’s mounting bracket using
an M12 grade 8.8 steel bolt and self-locking washer, or
