Aluminum Stair Instructions
Handrail Clearance
When placing the stair, a minimum of 6''
should be provided between the handrails
and any other object (a minimum of 12''
between handrails on two adjacent stairs).
Installation
1) Install the stair with the top tread at the
same elevation as the upper finished floor
or roof surface.
2) Prepare the mounting holes for the stair,
using the bolt pattern shown as a guide.
3) Put in position and securely bolt the
landing (top) and the footing (bottom) of
the stair. Bolts are not provided. Use
bolts or studs (minimum 1/2'' diameter).
4) If the stair is 15' or taller, you should
install bracing to prevent vibration.
