INSTALLING DRINK RAIL – STAIR PANELS
FOR CLASSIC COMPOSITE SERIES RAILING
1
PREPARE UPPER SUPPORT RAIL
Measure, mark and drill 3/16" diameter holes down through the upper support rail
at 15" on-center intervals
and second baluster at each end of the rail. These holes will be used to run anchoring
screws into the bottom of the deck board. Holes should be drilled to match the angle
of the stairs. A scrap piece of wood cut to stair angle may help.
2
CUT UNIVERSAL RAIL
AND DECK BOARD
Measure, mark and cut the 2nd
Universal Rail (purchased separately)
and deck board to length
Both ends need to be cut to match the
angle of the Top Support Rail.
For Between-the-Post applications,
trim both ends of deck board for a clean
finish (Dia. #2B). Place the Universal
Rail over the top support rail between
the post sleeves.
• For Over-the-Post applications,
proceed to Step 3.
• For Between-the-Post applications,
skip to Step 4.
