Fit Stair Railing Panels
• Position stair railing panel alongside 3" top
stair post and temporarily installed 3" bottom
post.
(Dia. 1A)
• Determine the desired center of the rail:
either a baluster hole or between two
baluster holes.
(Dia. 1C)
• Measuring from the determined center, cut
both ends of the rails.
• Position stair panel approximately 1 1/2"
above stair nosing.
Tip: lay a 2x4" board
flat on nose of stair treads. This will allow
enough room for installation of bottom
snap.
Clamp stair panel against top and
bottom 3" posts. Using a sharp #2 pencil,
mark the stair channels at four (4) locations.
• If using a continuous top rail, after panel has
been clamped to post, mark cut lines on the
H-channel and the 2" post using the bottom
of the H-channel to find your angle for post
cut.
(Dia. 1B)
• Remove clamps and cut stair panel at all four
(4) locations.
(Dia. 2)
Take care to cut stair
channels at appropriate stair angle. Use of
Miter saw with a sharp non-ferrous blade is
recommended.
• Clean cut areas and apply touch-up
paint on all exposed ends.
