PNEG-1112 Sidewall Bin Stair Assembly 37
Lower Support of the Stairs
1. In some cases the foundation is not as wide as the outside of the stair section. In this case, the
outside of the stair section needs to be supported to keep the stairs level. This should be done by
field fabrication of an angle back to the concrete foundation or supporting the outside rail with
blocks or a concrete pad. Use a level to check the stairs in all directions and shim the outside rail
when necessary.
Bottom Knee Brace
1. Attach the final knee brace to the bottom brace bracket using one (1) 5/16'' x 3/4'' bin bolt and
serrated flange nut. For clarity, the outside stair siderail is hidden.

2. Bring the knee brace close to the bin wall, and mark the hole where it attaches. Field drill the hole
with an 11/32'' steel bit, and bolt the knee brace to the bin wall using one (1) 5/16'' x 1-1/4'' bin bolt
and serrated flange nut.
