Platform Rail Installation 
1.  Tighten the nut at the top of the column to 85 ft-lbs before proceeding 
to step 2. 
Failure to tighten the nut at the top of the column could result 
in the stair becoming unstable and fall and result in serious 
injury or death.  
2.  Thread hardware (O) into the bottom of the platform rail post (18). 
3.  Secure the platform rail mount plate (28) to the top of the post with 
hardware (P). The mount plate should sit on top of the notches. 
4.  Place the second platform rail post (19) into positon over the pre-drilled 
holes in the platform and secure with hardware (Q and R). Make sure 
that the holes in the post face away from the platform. These holes are 
for the line rail that will be installed later.
