Center Column Assembly
1. Starting with a single threaded column section (5), screw a threaded
coupler (6) into the threaded end of the column section until
approximately 1” of the connector remains exposed.
2. Screw a double threaded column section (7) onto the exposed half of the
threaded coupler from step 1. Tighten until there are no gaps between
the column pieces.
3. Screw another threaded coupler (6) into the threaded end of the
assembly.
NOTE: Additional double threaded column sections (7) may be included
depending on the height of the stair being installed. Repeat steps 2 and 3 to
join the additional sections.
4. Screw the final single threaded column section (5) onto the assembly.
Tighten all of the sections of threaded column and ensure that there are
no gaps between the column sections.
5. Cut the length of the center column assembly to approximately 10” longer
than the floor to floor dimension.
The column sections must be fully tightened. Failure to tighten
the sections of the column together could make the stair
unstable and result in serious injury or death.
