4mm

TRU Zip’s patented zipper assembly is fully waterproof, dustproof, and submersible (IP67). Designed for ultimate reliability and ease-of-use, this zipper glides smoothly and secures into an overmolded garage for a confident seal you can feel. Constructed from extruded TPU, this durable zipper allows you to dream bigger (or smaller) than ever before.

The self-contained zipper assembly can be RF welded to create a new world of high-performance possibilities. The extruded zipper rails use both mechanical and vacuum forces to create a powerful seal that is highly resistant to shearing and separating forces. By combining an intuitive zipper design with leading-edge protection from the elements, TRU Zip makes what was once impossible, possible.

The 4mm size is perfect for smaller applications. For mid-size and larger designs, explore the 6mm and 8mm sizes.
