Base Positioning and Installation 
1.  Measure the platform from the mounting face to the center of the large 
hole to determine where to mount the base (1). 
NOTE: Alternatively, you can lay the platform on the lower floor to get a 
layout for where the column will fall. This is only possible if the mounting 
wall(s)/surface(s) extend all the way to the lower floor and are plumb. 
2.  After positioning the base, fasten it to the floor with hardware (A) and 
hardware (B). 
3.  Slide the baseplate cover (2) over the base (1). 
The lag screws securing the base to the floor must be installed 
and fully tightened before continuing with the installation 
process. Failure to do so could cause the stair to be unstable 
and could result in serious injury or death.
