Instructions for Cutting Directional Handle Length
1. Place nut on threaded rod.
2. Measure and cut threaded rod with hack
saw. Use the chart, Figure 2, to deter-
mine the length.
3. Remove the nut over cut end of threaded
rod. This cleans the threads after cutting.
4. Thread cut end of rod into hub.
5. Install the ceiling plate. The rotate/lock
lever must point toward rear of vehicle.
Be sure rotate/lock lever is pointing toward
back of vehicle and hole in ceiling aligns
with hole in ceiling plate.
NOTE: Make sure large and small keyways
line up in the hub and directional handle!
6. Measure and cut the directional handle,
Figure 3 and chart, Figure 2. NOTE: A
tube cutter is recommended for cutting
the directional handle. This gives a
square cut; a hacksaw does not. If using
an extension, allow for extra thickness
(see #7).
Figure 4 shows what points to measure
between, with and without a roof wedge.

7. The directional handle
and threaded rod will fit
roofs up to 5-1/4” thick. If
you are using wedges to
compensate for roof/ceil-
ing slope, be sure to
allow for this extra thick-
ness. You may add an
extension to the
directional handle for
thicker roofs. Each
extension will increase
the length of the direc-
tional handle by 2-1/4”.
