Chapter 2: Roof Stairs
Assembling the Roof Stair Sections
Roof Stairs may consist of a combination of 3-step, 4-step and 8-step sections (varies with diameter)
which are spliced together before being installed onto the roof.
Before You Begin
The following assembly instructions are for splicing three 8-step sections to form a roof stair section.
Refer to the table in General Information, page 15, for the number of stair step sections required for each
diameter bin.
1. Connect the assembled sets of stair sections (O) together using stringer splice plates (37), bolts (2)
and nuts (3).

2. Align and install the handrail posts (38) to the stair sections using the flange bolts (2) and flange
nuts (3).
NOTE:
• Determine the location of the handrail posts (38) for each diameter (see Figure 2-7,
page 22 and Figure 2-8, page 23).
• The handrail post connections should have the bolts oriented so the nut is outside the
walking area to eliminate a trip hazard.
• Do not tighten the flange bolts (2), leave hand tight until the stairs assembly is installed
onto the roof.
