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 the primary attachment fails.
Loop the safety cable through the attachment point
B
in the base of the fixture base (see
illustrations above and to right) and around a secure
anchoring point.
If a safety cable attachment point becomes damaged or
deformed, do not use the fixture. Return it to a Martin Service
Centre for repair.
