Platform Rail Installation 
1.  Place the platform rail onto the platform in the correct location.  The 
platform rail will be approximately ¼” away from the column and ¼” away 
from the end of the platform. 
2.  Using the holes on the bottom of the platform rail as a template, mark the 
location of the holes on the top and side surface of the platform. 
3.  Drill a ¼” diameter hole in each location.  
4.  Using bolt (G), nut (F), washer (D) and split washer (E), secure the platform 
rail to the side of the platform. 
5.  Using bolt (H), nut (F), washer (D) and split washer (E), secure the platform 
rail to the top of the platform.    
6.  If your stair has an extra platform rail, follow steps 1-5 to install the extra 
platform. 
NOTE: The platform rail will be approximately 2” shorter than the extra platform 
rail. Be sure to install the platform rail first and then the extra platform rail. 
The platform rail(s) must be installed on the platform of the 
stair. Failure to install the platform rail(s) could result in serious 
injury or death.
