ZipUp Parts
Wall Trim:  The "E" shaped trim that attaches around the entire periphery of your deck.
Main Rail:  The mounting pieces that run the length of your deck.  These rails support your Panels.
Ceiling Panel:  The panels are the ceiling surface that "Zip" into the Main Rails.  They are easily removed for cleaning or access to your deck framing.
Pitch Rail:  Rails used to impart a slope of 1/8" per foot in order to properly drain rainwater toward your gutter system.  (Ripping a treated 2x4 accomplishes the same thing for less cost.)
Seam Rail:  For decks with runs longer than 16'.

ZipUp Wall Trim


Mounts to the house and the 2 outside rim joists running perpendicular to the house.

12' Wall Trim - $23.33


ZipUp Main Rail

Mounting Rails that fit into the Wall Trim at the house, supports the Ceiling Panels and attach to the Pitch Rails.  You will need one less Main Rail than total number of Ceiling Panels.

8' Main Rail - $19.88 12' Main Rail - $29.80 16' Main Rail - $39.73




ZipUp Ceiling Panels

1st & Last Ceiling panel edge slips into Wall Trim on one side, and "Zips" into the Main Rail on the other side.  All others "Zip" into the Main Rails on each side.  To Calculate number needed, divide the width of your deck (in inches) by 12 1/8 (Center to Center of Main Rails) and round up.

8' Panel - $31.79 12' Panel - $47.68 16' Panel - $63.59




ZipUp Pitch Rails


Used to create slope for the panels from the house to the outer edge of the deck.  Use 1/2" for every 4'.  EXAMPLE:  If the deck runs 12' from the house to the outer edge, you would need 1/2" Pitch rail at 4', a 1" Pitch rail at 8' and a 1 1/2" Pitch rail (a 1" and a 1/2" combined) at 12'.  The Pitch rails run perpendicular to and attach to the bottoms of your joist.

12' x 1/2" Pitch Rail - $36.20

12' x 1" Pitch Rail - $47.72
