The bulk two-pack supports sewing projects that require redundancy or multiple items. Best for: stitchers creating rainproof jackets, down coats, or rainwear that benefits from robust waterproof tape and nylon coil teeth.

The 16″ length fits everyday jackets, rain shells, and small outdoor gear. Best for: crafters and hobby sewers who want multiple zippers for several projects.

This is a customize-your-length option suitable for DIY sewing or crafts, especially when you need long, uninterrupted runs.

Caution: ensure you select the correct slider style for your project, as some auto-lock systems differ in feel and operation.

The 78″ length (79″ end-to-end) reduces the need for multiple pieces. Best for: projects requiring formidable zippers that can endure frequent use and harsh conditions.

Buying Guide
What length should I choose?
Measure from the bottom of the zipper to the top where it closes. Choose a length that matches or exceeds the garment or gear opening. Longer zippers can be shortened by a professional if needed.
Which zipper teeth and tape matter most?
For outdoor durability, choose nylon coil teeth with TPU or waterproof tape. This combination resists moisture, maintains flexibility, and reduces the chance of water intrusion along the seam.
Is a separating zipper better than a continuous coil?
Separating zippers are ideal for jackets, coats, and tents that open fully. Coil zippers by the yard offer customization when you’re constructing or repairing gear with unique widths or multiple cables.
What about large or heavy-duty zippers?
Very large or heavy-duty zippers (like 78″ plastics) are best for bulk canvas, boat covers, or tents. They provide added strength but may be overkill for standard jackets or light rainwear.
Material considerations
Look for nylon or resin teeth with robust waterproof tape. Ensure the fabric you’re working with can accommodate the zipper width and thickness without compromising flexibility or seam integrity.
Which options are best for DIY projects?
Yard-length zippers with auto-pull sliders from trusted brands allow precise custom lengths. They’re suitable for makers building multiple items or prototyping gear layouts.
