HOW TO INSTALL ROUND OR SQUARE ALUMINUM BALUSTERS
TREX TRANSCEND

Installing Pressure-Treated Posts

  • Posts are to be installed 6' or 8' on center to accomodate railing length.
  • Attach posts using ½" carriage bolts.
  • Minimum joist size is 2x8.
  • Top bolts must be 1" from tops of joists.
  • Bottom bolts must be 5-1/8" from top bolts.

NOTE: Blocking can be added for extra strength.

Installing Post Sleeve Skirts and Post Sleeves

2.  Slide post sleeve skirt over post and down to rest on decking surface. Slide post sleeve over post and position inside post sleeve skirt.

Installing Railing Support Brackets (RSBs)

3a.  Mark 5-1/2" and 35-1/16" from deck surface OR for 42" height, mark 5-1/2" and 41-1/16" from the deck surface.
3b.  Place RSBs directly under the marks, center on posts, and secure with 2" wood screws (provided with post sleeve). Place top RSBs flat side UP, bottom RSBs flat side DOWN.

Cutting Railings
4.  Measure between posts and cut rails
to same length.

NOTES:

  • If using optional rail gaskets subtract 1/16" from each end.
  • Attach baluster spacers to railings 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 tighting 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.

Attaching Bottom Rail (Universal Rail) and Foot Block
NOTE: FOOT BLOCKS COME WITH SPECIFIC INSTRUCTIONS ON HOW TO ATTACH RAILINGS - ALSO REFER TO THESE INSTRUCTIONS AS WELL.

TREX RAIL

5a.  Center foot block in universal rail channel or on beveled bottom rail and attach. DO NOT extend foot block.
5b.  Lift bottom rail so RSBs are in the channel and attach with self-tapping screws (provided).

5c.  Telescope foot block down and screw through opposite sides. Place screw plugs.   TREX RAIL

Installing Aluminum Baluster Adaptor Strip and Baluster Spacers

6.  After bottom rail is fully installed, place aluminum baluster adaptor strip into channel of bottom rail, ensuring that itís fully seated into the channel. When rail lengths are non-standard, the baluster adaptor strip will need to be cut 2-1/2" shorter than the rail to allow clearance for the RSBís on each end.   TREX RAIL

7.  Snap baluster spacer into bottom rail. Place inverted baluster spacer on top of first baluster spacer.   TREX RAIL

Attaching Top Rail, Aluminum Baluster Adaptor Strip, and Balusters and Bottom Baluster Spacer
TREX RAIL TREX RAIL

8.  Place crown or rail on RSBs with balusters in rail channels. Attach top rail to RSB with two self-tapping screws (provided).
9.  After top rail is fully installed, place aluminum baluster adaptor strip into channel of top rail, ensuring that itís fully seated into the channel.

10.  Working at slight angle, press baluster through both baluster spacers and into bottom aluminum baluster adaptor strip, ensuring balusters are tight. Once balusters are seated into aluminum baluster adaptor strip of bottom rail, maneuver baluster into upper rail aluminum baluster adaptor strip. Some force will be needed to press balusters into place and level these.

Tip: Ensure balusters are level prior to attempting to slide baluster spacer up. This will allow for the baluster spacer to move up freely and snap into upper rail. Use of a rubber mallet to gently tap balusters in level is recommended.
