The 40″ Delrin #5 Open-End Locking Zipper features an auto-locking slider that stays securely in place until the pull tab is lifted for smooth, controlled operation. Ideal for garments, bags, and outdoor gear, it offers a reliable combination of strength, durability, and lightweight performance.

Constructed with Delrin (acetal) plastic teeth and durable polyester tape, it provides excellent resistance to moisture, corrosion, and most chemicals. The teeth will not rot or mildew, maintaining a clean appearance over time. Its low-friction properties allow for smooth, self-lubricating operation, while remaining strong yet lightweight.
