TRANSCEND RAILING
Cutting Railings and Baluster Spacers
4.   Measure between posts and cut rails to same length.
5.   Cut baluster spacers the same length as rails, equally 
spaced, so holes line up.
NOTES: 
»   If using optional rail gaskets, subtract 1/16" (1.6 mm) 
from each end.
»   Attach baluster spacers to railing before cutting to 
allow for cleaner cut and less work.
»   When measuring, cut equal lengths from each side of 
railing and baluster spacer to ensure equal spacing of 
balusters per each railing section.
»   In some cases, the gasket can be attached before 
tightening railing to RSB.
»   If gaskets are tight, use a small flat head screwdriver 
to compress the tabs of the gasket if they are stuck 
outside the rail.
IMPORTANT NOTES REGARDING FOOT 
BLOCK INSTALLATION: 
»   One foot block is REQUIRED for all 
railing spans. 
»   Refer to detailed instructions (Trex 
Transcend
®
 rail instructions) included with foot block 
prior to installation of railing section as these include 
other required steps for proper installation.

that is closest to post). 
If two hole bracket is included, attach with two self-
tapping holes (provided).
Attaching Top Rail – 
Crown Rail
8.   Place crown rail on 
RSBs. Attach top rail 
to RSB with three 
self-tapping screws
