Open Mid-Rail Aluminum Railing System
Standard Open Mid-Rail System
Each Panel Requires:
• 36" X 6' Panel Kit
• One additional Bottom Snap
• One unpunched H-Channel
• Rail Attach Kit (one kit for two panels)
• 6 Deck Rail Clips per bay
Continuous Top Rail Open Mid-Rail System
Each Panel Requires:
• 36" X 6' or 8' Continuous Top Rail Panel Kits
• One additional Bottom Snap
• One unpunched H-Channel
• Rail Attach Kit (one kit for two panels)
• Continuous Top Rail (span up to 18')
• 5 Deck Rail Clips per bay
• One Crossover Bracket
Important Note:
Prior to construction, check with your local regulatory agency for special code requirements in your area.
Common railing height is 36" or 42". Post spans will vary depending on job site conditions. Never span more than 8' on-center between railing
posts. Spans longer than 12' in length will require reduced post spans. When you cut a kit to create two panels, for instance, cutting 8' to two 4',
you will need an additional hardware kit. Read instructions completely to get an understanding of how the product goes together and how each
piece affects the other.
Important Information
• Please read all instructions completely before starting any part of the installation. Always make sure to visit www.TimberTech.com to
ensure you are viewing the most current installation instructions, care and cleaning, technical information and more.
• Impression Rail Express should be installed using the same good building principles used to install wood, composite, or metal railing and
in accordance with the local building codes and the installation guidelines included below.
• The AZEK Co. LLC accepts no liability or responsibility for the improper installation of this product.
• Impression Rail Express may not be suitable for every application and it is the sole responsibility of the installer to be sure that Impression
Rail is t for the intended use. Since all installations are unique, it is also the installer’s responsibility to determine specic requirements in
regards to each rail application.
• The AZEK Co. LLC recommends that all applications be reviewed by a licensed architect, engineer or local building ofcial before
installation. If you have any questions or need further assistance, please call AZEK Customer Service at 877-ASK-AZEK (877-275-2935),
or visit our website at www.TimberTech.com.
• Impression Rail Express is tested as a whole system and should be used that way. It is not intended to be used in conjunction with other
railing systems or fasteners.
• The following Installation Guidelines are applicable for installation of Impression Rail Express only.
• IMPORTANT: Make sure the DRIVE TOOL/DRILL is congured or set to use the SCREW setting when driving and/or tightening all
FASTENERS.
• SAFETY: Always wear goggles when handling, cutting, drilling and fastening materials.
• Failure to install this product in accordance with applicable building codes and Impression Rail Express’s written Rail Install Guide may
lead to personal injury, affect rail system performance and void the product warranty.
• The buildup or generation of static electricity is a naturally occurring phenomenon in many plastic based products such as carpeting,
upholstery, and clothing, and can occur on alternative decking under certain environmental conditions. This static electricity can discharge
once contact is made with hardware, railing, or other conductors of electricity.

boards and into blocking. (Dia. #3C)
• Drill a 5/8" hole in center of four deck screw
holes for lighting wires (optional).
• Level and plumb post using shims.
• Secure posts to deck frame with suggested
screws. (Dia. #3B)
*Verify local code requirements for post
attachment hardware.
• Install post caps (after panels are installed).

required to reach 6' and 8' lengths.
• Stair railing panels are shipped at a
37 degree angle. Panels are adjustable
+/- 3 degrees.
• Maximum post spans on stair railing
application is 96" on center. Additional posts
are required on any stair application more
than 8' in length.
• For all other applications, consult a design
professional or an Impression Rail®Express
representative for more information.

1Fit 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
at 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 nd 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.

• After stair panel has been cut to proper size
and angle, place the panel on the 2x4″ (or
hold 11/2″ above stair nosing) board, between
the 3″ posts. Use a #2 sharp pencil to draw a
line across the top of the lower H-channel in
two places (Dia. 3).
• Remove panel and bottom post. Attach stair
panel attach clips at marked location as per
(Dia. 4) and fasten with #8x3/4″ self-drilling
screws.
• NOTE: Rail clip jigs are not used for stair
panel installation.

re-attach the lower 3″ post to the bottom step or
landing. Place the stair panel onto the lower stair panel
attach clips (Dia. 5).
• When lower extrusion is fully seated on lower clips,
insert stair panel attach clips into upper extrusion.
Secure attach clips to post with 2-#8x3/4″ self-drilling
screws, then secure upper extrusion to stair panel
attach clip with 2-#8x3/4″ self-drilling screws. Repeat
this same procedure for bottom post, upper extrusion
(Dia. 6).
• When upper extrusion is secured to attach clips, return
to lower extrusion and secure lower extrusion to lower

ends.
• Snap each rail snap over the corresponding rail
channel until properly seated (Dia. 8).
