Zip-Up UnderDeck Main Rails are a crucial component in creating an attractive watertight underdecking system in your outdoor space. The Main Rail features a specially-designed channel which connects with the beadline built into Zip-Up Panels to form a water and rainproof seal. Attaching directly to the Pitch Rails installed on your joists, Main Rails are attached with standard 1 to 1-1/2 inch long deck screws (sold separately). Long-lasting and incredibly easy-to-install, the Zip-Up UnderDeck systems expands your home's living space to include more backyard parties and cozy nights out while adding value to your home.
Zip-Up UnderDeck Main Rails are available in the versatile colors of White, Beige, and Gray, and are offered in both 12 foot and 16 foot lengths.
