Installation of Monorail:
Junction
Box
1. Extension Wires are supplied to connect

and black hot wire to black wire with wire nuts.
The Ground Wire may be green or bare copper,
connect it to the green wire and mounting
crossbar ground wire using a wire nut.
2. Carefully pass the Extension Wires through
the center hole of the supplied Crossbar/Threaded
Nipple assembly, then secure crossbar to the
