Longer balusters may
be required in order to
meet local code
referring to top rail
heights.
Tips:
When cutting balusters
trim off as little material
as possible to ensure a
full length baluster.
Use stop block on Mitre
Saw for equal length
balusters.
IMPORTANT
Make sure that the
DRIVE TOOL/DRILL
is configured or set
to use the SCREW
setting when driving
and/or tightening all
FASTENERS.
WARNING: Be sure to check
local code requirements for proper
bottom rail location and top rail
height and be sure that you have
the proper height balusters to meet
those requirements.
For best results, use a
center support block on
stair section 4ft in length
or longer.
