INSTALLATION OF HORIZONTAL SWIVEL RAILING
TREX SIGNATURE
STANDARD
NOTES:
» WHEN USING SIGNATURE HORIZONTAL SWIVEL BRACKETS BOTH 
BOTTOM AND TOP RAILS WILL NEED TO BE MEASURED AND CUT TO 
APPROPRIATE LENGTHS. 
» HORIZONTAL SWIVEL BRACKETS CAN BE USED UP TO A 50º ANGLE FOR 
SIGNATURE RAILINGS. 
» WHEN USING HORIZONTAL SWIVEL BRACKETS VERY IMPORTANT 
TO LAY OUT LOCATION AND ORIENTATION OF POSTS AND SWIVEL 
BRACKETS BEFORE INSTALLING SWIVEL BRACKETS.
» WHEN RAILINGS ARE CUT TO ODD SPANS, ALL SPANS GREATER THAN 
5' (1.52 M) (EXAMPLE: 8' (2.44 M) SPAN CUT INTO ONE 5' (1.52 M) SPAN 
AND ONE 3' (0.91 M) SPAN) WOULD REQUIRE FOOT BLOCK UNDER 
5' (1.52 M) SPAN SINCE SMALLER FIXED BALUSTER IS NO LONGER 
CENTERED.
How to Measure and Cut Bottom and Top 
Railings
1.   With brackets in correct swivel location, measure 
distance from inside of bracket to inside of bracket. 
ENSURE THAT BEFORE CUTTING, BALUSTERS 
HOLES ON BOTH BOTTOM AND TOP RAIL LINE 
UP. ALSO MAKE SURE CENTER BALUSTER SLOT 
IS AS CLOSE TO THE MIDDLE OF THE SPAN AS 
POSSIBLE. In some cases due to odd railing spans, 
the center baluster may need to be offset in one or 
the other direction to ensure there is enough room at 
both post locations for balusters to be placed.
Cutting Bottom Rail and Bottom Rail Cover
2.   Cut bottom rail to the measurement between the 
bottom swivel brackets.
3.   Slide rail insert out and cut 3/4" (1.9 cm) FROM 
EACH SIDE of insert, then slide back inside rail 
and center.
4.   Mark and cut bottom 
rail cover 1-1/2"
(3.8 cm) shorter than 
bottom rail.
