WARNING: Prior to painting or finishing the completed
balustrade, verify all exposed ends of newels, balusters, and
railings are adequately sealed. Complete sealing is
necessary to protect the wood from weather damage.
After finishing the handrail section, the assembly can be
attached to the newel posts using two lag bolts and washers
from inside the newel post box. As an alternative, you may
choose to angle screws into the newel post from the
underside of the rail. Once the rail is secured, the newel cap
is installed and attached to the newel box using galvanized
finish nails or screws.
NOTE: For long sections in the rail assembly, support spacers
between the shoerail and the floor are recommended to
reduce sagging. The spacers should be placed every two to
three feet and at each end of the assembly.
