Building codes are very specic on
allowable angles and widths. It is very
important to consult with your local building
code ofcials and plan your stair layout
accordingly. Leave adequate space for
graspable hand rail if applicable.
Note: The slope of the stairs can be 30 to
37 degrees.

Square Composite Balusters: Transfer the stair
angle to the balusters, and cut the balusters
to desired length.
Note: Round metal balusters are pre-cut on
one end. If a custom angle is required, cut
the factory angled end, leaving the square
end as is. This will allow proper seating
when securing the top of the balusters later
in the installation.
