2.
Fasten the omega holder to the U-holder (4) of the fixture by inserting both quick-lock fasteners (3) into
holes in the U-holder and tighten fully clockwise.
3.

.
For securing the fixture to the truss, install a safety wire that can hold at least 10 times the weight
of the fixture. Use only a safety wire with a snap hook with screw lock gate. Pull the safety
wire (11) through the U-holder (4) and around the truss (12) as shown on the picture below.
5.
The tilt lock (7) allows to adjust the fixture to desired position. In case, that the tilt lock cannot
be loosened (tightened) due to the housing of the fixture, pull this tilt lock in a direction from the fixture,
turn it to desired position, release it and continue in loosening (tightening) this tilt lock (principle of
a "ratcheting socket wrench").
If two and more fixtures are to be connected in a top-to-bottom method, a stacker with two safety wires
has to be used - see article below.
Multiply fixtures rigging
Maximum 6 fixtures can be connected in the top-to-bottom method
Always use a stacker for a hanging multiply fixtures installation . The position of the U-holder allows to tilt the
whole "stack" of fixtures.
To change the position of the U-holder
1. In order to release the U-holder (4), press and hold the front part (1) of the pin (2) and pull it out from
the stacker. Use the same way to remove the pin (2) on the opposite side of the U-holder.
2. Move the U-holder to desired position.
3. Press and hold the top part (1) of the pin (2) and push it throw the U-holder into the hole in the stacker.
Secure the second side of the U-holder (4) by inserting the pin (2) into the stacker.
Check, that both sides of the U-holder are securely fastened.
