ALUMINUM BALUSTER
INSTALLATION INSTRUCTIONS
Step 1: Measure railing opening from post to post to determine
the length of each baluster rail section (fig. 1).
Step 2: Cut top and bottom rails (2x4s) to length and clamp
together. Mark top and bottom rails 4-1/2" on-center, starting
from the center of the rail (fig. 2).
Step 3: Using a drill driver, screw on baluster connectors at each
mark using the screws provided (fig. 3). Apply silicone caulk on
each connector to prevent balusters from turning or rattling after
installation is complete. The caulk should be on the outside of
the connector, where the baluster will make contact with the
connector’s outer edge.
Note: Specific types of treated lumber are known to corrode
aluminum. The baluster connectors provide a barrier between
the aluminum balusters and treated lumber to ensure long-term
performance.
Step 4: Place the bottom rail between the rail posts, supported
by a 3" block (2x4 scrap material works best) (fig. 4). Secure
rail to posts using rail connectors (sold separately) and slide
balusters over the bottom connectors. Carefully place top rail
over the balusters, making sure each baluster is seated
properly on each connector (fig. 5).
Step 5: Inspect finished railing for proper baluster spacing
and secure top rail. Add a cap rail for a finished look (fig. 6).
Step 6: For rail sections longer than 4', support blocks are
recommended. These can be made from leftover 2x4 rail
material. Properly position the support block and toe-nail
it to the bottom rail and deck board (fig. 7).

Kit contents
• 15 - Aluminum balusters
(2.5 balusters required
per linear foot of railing)
Preparation
Items you will need
• Rail connectors
(sold separately)
• Drill driver
• Tape measure
• Clamps
• Safety glasses
• Carpenter’s pencil
• White rubber mallet
• Support blocks (can be
cut from scrap rail material)
Prior to construction, check with your local regulatory agency
for special code requirements in your area. Common railing
height is 36". Structural support should come from either the
continuation of deck support posts that extend up through the
deck floor or from railing posts that are bolted to the inside of
the rim or outer joist. 6' on-center post spacing is recommended.
Never span more than 8' on-center between railing posts.
