4.1 General
4.2 Fastening Support Hardware to Bar Joists - Perpendicular
Threaded rods (hangers) must be provided for attachment to the end couplers of both the first and last rail
section in every system run. One threaded rod is to be located at least at every second rail section coupler.
When completed, there should never be a span of more than two rail sections between support rods.
Additional B-channel, installed spanning two rail couplers, may be added along the centerline of the rail to
provide mounting points for extra threaded rods, guy wires, etc. or to circumvent overhead obstructions.
Figure 4-1 illustrates a typical installation of the CurveTrack® rail to bar joist ceiling construction using pre-
cut lengths of M10 threaded rod. See paragraph 3.3, Planning Installation of the System Run, to determine
hanging height, and paragraph 5.2, Cutting the Threaded Rod, before cutting the threaded rod.
Locate the approximate centerline of the system run and install a taut string line over the full
length of the system run. Install the string as high as possible making certain it remains clear of
all obstructions.
Thread a M10 x 1.5 hex nut (1, Fig.4-1), M10 spring lock washer (2, Fig. 4-1) and a square washer
(3, Fig. 4-1) onto one end of each threaded rod (4, Fig. 4-1) so that 100mm, plus the height of the
bar joist angle, is extending beyond the square washer.
Insert the end of the rod assembly between the bottom angles of the bar joist and fasten loosely
with a square washer (5, Fig. 4-1), lock washer (6, Fig. 4-1), and hex nut (7, Fig. 4-1). Do not
tighten until the associated track section is hung and aligned.
