Assemble Steps to Siderails
Stair Section Assembly
The 2 step, 3 step, and 4 step stair sections are all assembled in the same fashion. The following
instructions are for assembling a 3 step stair section.
The inside stair siderail is different from the outside stair siderail in the same way as the inside and
outside siderail extensions. The outside stair siderail has three (3) slots at its ends, while the inside stair
siderail has two (2) slots. The painted edge should be at the top of the stair section.

Assemble the steps.
1. To the inside stair siderail, loosely attach a 9'' x 20'' step using two (2) 5/16'' x 3/4'' bin bolts and
serrated flange nuts. The heads of the bin bolts should on the outside of the inside stair siderail and
not to the inside of the step.
