The 8# TPU Waterproof Zipper (open-end type) is built for outdoor and protective applications that need reliable resistance to water and dust. It is made from TPU-coated polyester tape with an exposed nylon coil, so it stays flexible and smooth to operate even after long outdoor exposure.
The TPU film is laminated on the slider side of the tape. It shields the closure from rain, splashes and dust. The open-end design gives you a fully separable closure for covers, bags and outdoor gear.
