Two fully loaded packs weigh 80 pounds (36.2 Kg.), not including wire weight.
Packs mounted to Unistrut supports:
Note:
If more than two packs are mounted together the mounting holes are no longer on 16" centers.
• Using the dimensions shown in Figure 1 mark the wall with the locations of two horizontal mounting channels.
• Fasten two mounting channels, Unistrut P3300T or equivalent (not supplied), to the wall at each vertical stud or framing member.
• Insert Unistrut nuts (not supplied) on 14” (356mm) centers in each channel for each pack section to be mounted.
• Remove the 3 bolt hole knockouts and the ¾” T.S. conduit knockout on the mating sides between adjacent packs. Bolt packs together with ¼” bolts, internal-tooth
lockwashers (one under bolt head and one under nut), and nuts (not supplied). Bush control wire knockout with ¾” T.S. chase nipple or equivalent (not supplied).
- Mount the pack assembly to the mounting channels using bolts and lockwashers.
Semi-Recessed Packs:
•
Locate semi-recessed mounting kit, Model Number 600-906 (shipped separately).

• Mount the pack in the wall to two studs or other suitable structure with #12 flat head wood screws (not supplied) or other suitable fastener. Adjust the mounting
brackets if necessary to make sure the back of the black extrusion is at least 1/8” (3.175 mm) in front of the finish wall surface.
- Skip to Step 3 for conduit installation instructions and then return to this step.
- Attach the two vertical parts (countersunk holes) of the trim frame to one of the horizontal parts (tapped holes) with 2 black flat-head 6 - 32 screws (supplied).
