Read all instructions BEFORE installation.
NOTE: All Transcend railings and gaskets ONLY work 
with stair slopes of 32°-37°.
Installing Posts, Post 
Sleeve Skirts, and  Post 
Sleeves for Stair Rails 
1.   Install posts, post 
sleeve skirts, and post 
sleeves according to 
standard Transcend 
railing instructions. 
See page 65. 
»   In most cases, a post and post sleeve longer than 
39" (991 mm) will be needed on the lower section of 
stair rail to accommodate stair angle.
»   Make sure top and bottom posts for stairs are 
installed at nose of each tread.
Measuring and Cutting 
Bottom Stair Rail
2.   Place a 1" (254 mm) 
deckboard on the nose 
of the stair tread. 
3. Snap baluster spacer into lower stair rail and lay 
lower stair rail on top of the deckboard.
4.   Use the lower and upper stair post to set the length 
of the lower stair rail. Ensure that baluster spacer 
holes are spaced evenly between posts. Also allow 
for a minimum of 1-1/2" (292 mm) at each end of 
the stair rail for bracket placement and baluster 
clearance. Mark rail at post intersections.
5.   Remove lower rail, 
keeping baluster spacer 
in rail, and cut along 
marks.
NOTES: 
»   If using railing gaskets,  
subtract 1/16” from 
each end and cut.
»   KEEP BALUSTER 
SPACER IN RAILING  
WHEN CUTTING.   
CUT VERY CAREFULLY  
TO NOT BREAK BALUSTER SPACER.
Attaching RSB’s for Bottom Stair Rail
6.   Remove baluster spacer from bottom rail and place 
rail in between posts, keeping rail on deckboard.
