For 6-ft. rails sections, position the crush
block and holder inside the bottom rail at the
approximate center point.
For 8-ft. rail sections, position the two crush
blocks and holders inside the bottom rail at
the approximate 1/3 and 2/3 points.
Secure crush block to crush block holder
using a supplied #8 flat head screw. Do not
over-tighten.
Note: The screw will be off-center in the
crush block.
Before assembling the crush block, transfer
the stair angle to the end of the crush block,
dry fit, and cut to fit.
Dry fit the assembled section and use the
bottom rail to scribe a light line on the post
to determine the location of the bottom rail
bracket.
Note: For best results, predrill bracket holes
on post with a 1/8-in. - 5/32-in. bit to ensure
accurate screw placement and full insertion,
particularly as the stair angle increases.
Secure the bottom stair brackets to the post
using the supplied #10 x 2-1/2-in. at the
desired height. Do not over-tighten.

Note: It is important to ensure balusters
are level when securing. Shim the H-bar
with a 1/2-in. - 5/8-in. spacer to ensure
the balusters remain fully inserted when
securing.
Square Composite Balusters:
Move the
baluster guide to the top rail end of the square
composite balusters.
Position the top of the balusters tightly
against the inside of the top H-bar. Center
the balusters under the side-mounting screw
holes. Working from one end to the other,
secure each baluster using the supplied
#8 x 1-1/2-in. flat head screws. Do not over-
tighten.
Note: The screws should penetrate fully
through the baluster.
Secure the remaining balusters working to the
other end. Do not over-tighten.
Round Metal Balusters:
Insert the round
baluster holders into the aluminum H-bar,
ensuring that the angled hole is oriented
correctly and that the through hole aligns with
the side holes in the H-bar.
Fully seat all balusters into the holders. Secure
an end baluster first, using the supplied #8 x
1-1/2-in. flat head self-drilling screws through
the H-bar side holes.
Pivot the H-bar toward the remaining
balusters, inserting them into the holders.
Start from the secured end and work
to the other end. Secure the remaining
end baluster, and then the remaining infill
balusters.
