RESIDENTIAL SPIRAL STAIR
All Wood Construction
This is a 52" diameter oak staircase with balcony rail to
match. The handrail is # 240 (3 1/2" x 2 3/8") molded oak; balusters
are a # 334 (1 1/4" square) one per tread; and the treads are
a # 142 (1 1/4" thick). The center column is solid oak and
is 5 1/4" diameter. The balcony rail is 42" high from the floor
to the top of the rail with the same spacing in between the
balusters to match the stair. The stair was shipped as a kit
for easy installation at the job site. The final finish was
applied to the stair after installation.
