Installing Stair Railing with Architectural
Balusters
1. Installing Posts for Stair Railing
See instructions on page 94.
Cutting Lateral Rails and Measuring
Baluster Spacing
2. Cut top and bottom rails the distance between
posts and determine angle of end cuts and mark
centers. Use equation (above) to determine
number of balusters needed.
Installing Foot Blocks
3. Cut square balusters for foot blocks and place
every 18" (45.7 cm) on lateral bottom rail. Toenail
screws into foot blocks and bottom rail to secure.
Installing Top and
Bottom Lateral Rail
4. Connect rails to posts
with “L” brackets or
equivalent construction
methods.
Installing Balusters
5. Measure distance between posts to determine
center point of top and bottom rails. Install first
baluster with four 1-1/2" (6.4 cm) exterior-approved
screws. Space balusters a maximum of 3-1/2"
(8.9 cm) edge-to-edge.
NOTE: A 2" x 4" (5.1 cm x
10.2 cm) can be used for spacing
the architectural balusters.
