2. Installation
Read and follow these directions carefully before an attempt is made at
installation. The GSI Group is not responsible for damage or accidents ca used by
improper installation or installation procedures. Our stairs are designed to
support the weight of one (1) person, and the weight that they can carry.
NOTE: The sidewall bin stair assembly can be installed ascending or descending, clockwise or
counterclockwise, when looking at a top down view of the bin. Also, they can be installed while
the bin is being assembled/erected, or after the bin is installed. The following assembly
instructions will show a descending clockwise installation after the bin has been installed.
NOTE: Care needs to be taken to ensure that nothing will obstruct the construction path of the stairs,
such as doors, conduit, heaters, fans, unloading equipment, etc.
NOTE: All platforms are 39'' long, and extend 26'' from the bin wall.

points, and where you will have to field drill.
4. Line up the correct hole in the platform wall bracket with the first horizontal seam bolt row. The
correct hole is indicated in the detail view of the corresponding layout figure. Knee braces should
be installed at the same time as the platform wall brackets.
5. Mark the location of the holes to be field drilled for the platform wall brackets, stair wall brackets
and knee braces, as shown by the corresponding layout figure.
NOTE: All stair wall brackets should line up with a hole in the horizontal seam bolt rows, except for a
platform being installed 26-1/2'' below the eave on a 44'' bin sheet. Using the center hole on the
stair wall bracket, place it approximately two (2) bolts over and one (1) hole down from the
platform wall bracket attachment point to the first horizontal seam bolt row.
Drilling and Installation
1. Using the marked holes from the previous Steps, field drill the mounting locations as indicated in
the corresponding layout figure. Use an 11/32'' steel drill bit to make the holes.
2. Mount the platform wall brackets, stair wall brackets, and the knee braces with the provided
5/16'' x 1-1/4'' bin bolts and serrated flange nuts. The highest two (2) knee braces need to be the
42-1/2'' knee braces, instead of 34-3/4'' knee braces that may be part of the package.
3. At the bottom of the bin, the final wall bracket and knee brace will be installed with the final
stair section.
4. One (1) bolt spacing is the distance between the bolts on the horizontal seams, which is
equal to 9-3/8".
5. For 32" bin sheets: Each stair wall bracket after the first bracket will be lo cated three (3) bolt spaces
over (28-1/2") and one (1) horizontal seam down.
6. For 44" bin sheets: Each stair wall bracket after the first bracket (second bracket for 26-1/2" below
