Understanding Zipper Types & Zipper Size Rating:

The numbers #5, #8 and #10 refer to the size or gauge of the zipper. The number represents the width of the zipper teeth in millimeters. For example, a #8 zipper has teeth that are 8mm wide.

Consider the type of fabric or material you are working with. For tough projects with thick materials, use a #10 zipper to handle the extra stress of heavy canvas or vinyl.

#5 Zippers:

  • Common Uses: Lightweight garments, smaller bags, pockets, and other applications where a smaller zipper is appropriate.
  • Advantages: Lightest weight, suitable for projects where minimizing bulk is crucial.
  • Considerations: Not as robust as #8 or #10 zippers, best for lighter applications.

#8 Zippers:

  • Common Uses: Apparel, bags, cushions, tents, and other medium-duty applications.
  • Advantages: Lightweight, flexible, suitable for projects where weight is a concern.
  • Considerations: May not be as heavy-duty as #10 zippers.

#10 Zippers:

  • Common Uses: Heavy-duty zipper applications like industrial bags, tents, boat covers, and other items that require robust closures.
  • Advantages: Sturdy, durable, ideal for high-stress situations or heavy materials.
  • Considerations: Heavier and may be overkill for lighter applications.

Types of Zippers:

PowerLock Zippers are offered in both fixed-length separating zippers, or zipper chain by the yard.

Weight & Durability

If the zipper will be subject to frequent use or stress, a #10 zipper's sturdiness may provide longer-lasting performance. For projects where weight is a critical factor, such as with lightweight backpacking gear or apparel, a #8 zipper might be preferable due to its lighter weight.
