System Installation Guide
4.3 Fastening Support Hardware to Bar Joists - Parallel
When the installation requires the system run to be parallel to the bar joists, metal channel is used as a spanner
to bridge the bar joists at each mounting point of the system run as shown in Figure 4-2.
Lengths of channel should be cut 0.3 meter longer than the distance between the bar joists to allow for mounting
hardware.
Install the first and the last channels on the system run. Determine the centerline of the system
run and mark it on each channel.
Place channels on bar joists every 4.8 meters so that there is one channel for each threaded rod
assembly and that each channel is placed at the same location, relative to the string
line (refer to paragraph 4.1).
Center channel (1, Fig. 4-2) over bar joist bottom angles with the open side of the channel facing
down. Slide M10 channel lock nuts (2, Fig. 4-2) into each end of the channel until they are
centered between joist angles.
Assemble M10 x 1.5 hex nuts (3, Fig. 4-2), M10 spring lock washers (4, Fig. 4-2)
and square washers (5, Fig. 4-2) onto two M10 x 1.5 x 150mm hex head cap screws (6, Fig 4-2).
Insert screw end between bar joist angles and thread into Twirl nuts. Do not tighten screws
securely until the rail section is hung and aligned.
