2. Installation
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.

determined by the sheet size of the bin, and the distance below the eave, the platform will
be installed.

Read and follow these directions carefully before an attempt is made at
installation. The GSI Group is not responsible for damage or accidents caused 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.
