5. If spacers are required, remove the tread and add the correct number of
spacers on top of the sleeve. All spacer must go on top of the first sleeve.
NOTE: The spacers have small bosses on one side and indents on the other.
The bosses should sit in the indents of the adjacent centering ring or spacer.
6. Reinstall the tread (6) on top of the spacers (if any were required) and
remeasure the height of the top of the tread. It should be within 1/8” of
the riser height calculated in Step 4.
7. Slide a centering ring (4), sleeve (3), and centering (4) down the column.
Ensure that the flanges of the centering rings extend into the sleeve.
