Slide a short U-frame over the first square drive-
shaft and push it in as deep as possible into the
opening at the bottom of the post. (Figure 72)
Note:
The U-frame end that has one hole must
go toward the post assembly and the end that
has 2 holes must go toward the rear of the cover.
(Figure 73)
CAUTION
•
Be sure the U-frame is fully inserted into the
post so the length sticking out is 25 in. (63.5
cm).
•
Be sure the U-
frame’s extrusion is well
inserted in the footplate insert as shown in the
detailed view of Figure 75.
•
Be careful not to damage the paint on the U-
frame or the outer sleeve while inserting the
U-frame into the post.

screw through the hole, put a5/16-18 nylon nut
from the other side and 5/16 nylon washers on
both sides. (Figure 74).
WARNING
Be sure the U-frame is properly locked in
place by the 5/16-18 x 2 in. hex cap screw, as
shown in Figure 75, by pulling it.
CAUTION
•
Do not overtighten the screws or use any
power tools as it could break the U-frame or
the hardware itself.
