How to Measure and Cut Bottom and Top Railings of 
Trex
®
 Signature™ Panel (When REQUIRED)
1.   Position panel between posts and align with bottom 
bracket. Align center baluster with middle of span 
between posts (this will allow for equal spacing 
between end balusters and each post). Mark 
bottom and top rail at each end.
NOTE: If the end balusters fall too close to the brackets, 
the center point can be adjusted one baluster to the left 
or right to allow more room. 
Cutting Bottom Rail
2.   Using a saw equipped with a non-ferrous metal 
blade, cut each end of bottom rail and bottom rail 
insert 1/4" (6 mm) shorter than mark on each end to 
allow for fit into bottom rail brackets.
Cutting Top Rail 
Option 1: 
For Post-to-Post Configuration
3a.   Using a saw equipped with a non-ferrous metal 
blade, cut each end of top rail 1/4" (6 mm) shorter 
than mark to allow for fit into top rail brackets.
Cutting Top Rail
Option 2: 
For Post-to-Crossover Post Configuration
3b.   Top rail must be cut differently on each side of the 
rail. Railing side that attaches to standard post 
should be cut 1/4" (6 mm) shorter than the mark to 
allow for fit into top rail bracket. Railing side that 
attaches to the crossover post should be cut 
3/4" (19 mm) LONGER than the mark to allow for fit 
into the crossover post bracket.
