We have developed an optional safety wire that secures the plastic shells to the head of the MAC 500. The wire has P/N 50300502. Two wires are required per fixture.
The wire has a closed loop at one end and a simplex hook at the other end. To secure the shell:
- Place the closed loop under a washer and screw in the lamp housing counterweight.
- Loop the wire around a cross rib between the shell ventilation slots and hook the wire to itself. Do not attach the hook directly to the plastic rib.
