Optional Peak Rail Assembly
The peak rail is an option to the roof stairs and is intended to be assembled to the roof stairs.
1. Bolt the two extensions (234068) to the upper vertical handrail support C-sections on the roof stair (fIGURE
21). Note that these supports should be installed such that the center web of the C-section is on the inside
of the bin (towards the peak ring). The tops of the peak rail extensions protrude about 8 ½” above the
vertical handrail supports. They are bolted on, such that the protruding legs of the angles are on
the inside and pointing towards the peak ring.

2. Preassemble the peak rail support posts (234092) to the support clips (234093) such that when the clips
match the slope of the roof, the support posts are vertical. The flange on the support posts should be
oriented such that the peak rails are attached on the inside of the support posts.

3. Using U bolts, loosely secure one peak rail tube to the extensions (234068) that are attached to the roof
stair handrail support posts and the second tube to the mid-point of the handrail support posts. At the
upper location the tubes should butt up against the flange of the extensions. At the mid-point
location, the tubes should not protrude inside of the plane of the handrail support. Once the tubes
have been leveled (as per the following instructions) it is necessary to secure the ends of the tubes using
self-drilling screws at the two locations referred to here. Drill in from the outside of the tubes, through the
pilot holes provided.
