Step 6
Connect and Install the spacer channel pulley bar
Line up the hole in the end opposite the pulley of the spacer channel pulley
bar (D) over the hole in the second spacer channel pulley bar. Thread a ¼”
x ½” bolt (P) into the hole and finger tighten.
(SEE FIG. 6)
Press the spacer channel bar flush with the ceiling and mark with a pencil
where the lag bolts will be used to attach the bar to the joist.
--Perpendicular joist installation
(option A or B on page 7). There are sets of
holes on each side of spacer channel bar at 16” and 24” from the
last
lag bolt
installed. Measure from the last lag bolt and determine the appropriate holes
depending on your joist spacing. Remove the spacer channel pulley bar.
--Parallel joist installation
(option C or D on page 7). Make marks at one hole
before the pulley and one hole after the pulley. Remove the spacer channel
pulley bar.
It is very important that the lag bolts are fastened to the center of the joist.
Use the hole saw drill bit (U) or cut away the drywall with a utility knife to
obtain an unobstructed view of the width of the joist so the exact center can
easily be determined. It may be necessary to reposition the spacer channel
pulley bar and mark with a pencil where the lag bolts are to be fastened.
Using a power drill with a 18” drill bit attached drill two pilot holes into the
center of the joists.
Line up the hole in the end opposite the pulley of the spacer channel pulley
bar (D) over the hole in the second spacer channel pulley bar. Thread a ¼”
x ½” bolt into the hole and tighten with a ratchet or adjustable wrench until
the spacer channel pulley bar is securely fastened.
(SEE FIG. 6)
Place a washer (L) over the lag bolts (K) and using the hex key (W) fasten
the screws into the joist until the spacer channel pulley bar is securely
fastened to the joist.
