Symmetry Railing Installation Instructions - 10-ft. and 12-ft. Stair
11
Building codes are very specific on allowable
angles and widths. It is very important to
consult with your local building code officials
and plan your stair layout accordingly. Leave
adequate space for graspable hand rail if
applicable.
Note: The slope of the stairs can be 30 to
37 degrees.
Use a 1x4 or similar support to bridge at
least three stairs to establish the stair angle.
Place the bottom rail between the stair posts.
Center the hole pattern between the posts
allowing a minimum 2-1/8-in. from rail end to
routed baluster holes.
Transfer the stair angle to the bottom rail.
Install 4x4 posts in the pre-determined
locations, cover with post sleeve and verify
spacing. Posts should be plumb in both
directions. Place post sleeve base moulding
over post sleeve and slide it down to the deck
surface.

Note: Rail lengths will vary slightly due to
manufacturing processes. Make sure rails
are cut to correct length.
Transfer the stair angle to the balusters, and
cut the balusters to desired length.
To cut the H-bar, first place the H-bar on
its side with the holes nearest to the cut
bottom rail. The bottom rail should be top
side up. Align the hole pattern with the cut
bottom rail.
Cut the U-channel, it will fit snugly inside the
bottom rail. Set U-channel aside until Step
17.
Note: The bottom rail and U-channel can be
cut together to save this step.
Place the Bottom U-channel into the cut
bottom rail. Transfer the cut angle and length.
