Safety bonds
To protect against the fixtures falling if the main
rigging point fails, you should fit a safety bond to
the attachment point on the back of each fixture.
If fixtures are linked together into a larger array,
you should still attach a safety bond to each fixture
since a failure of a coupler could cause parts of the
assembly to fall. However to make rigging easier
you can attach the top one round a fixed point,
then loop the lower safety bonds into each other as
shown in the picture.
Mounting the junction box
The junction box may be mounted directly to a surface using the holes provided on the side
flanges, or a rigging clamp (such as the Super Lightweight Half Coupler Rigging Clamp black: P/N
91602018, listed in the accessories) may be attached to the rear side using an M10 bolt.
