A Zipper Replacement guide

Whether you need a 23 inch zipper, a 9 foot zipper, or something even longer (or shorter), we are your source! Read on to hone in on your perfect zipper.

For those who are new to the world of zippers, there are 6 important pieces of information you need to know to find your perfect zipper. The guide below walks you through all of the relevant information you should gather to find your specific zipper on our website. Once you have all of this information, your zipper should be a cinch to find by navigating to Zippers by Gauge or Zippers by Material !

1. Type of Zipper Teeth

Some of them are:

  • Aluminum Metal
  • Antique Brass Metal
  • Antique Nickel Metal
  • Brass Metal
  • Copper Metal
  • Invisible (hidden teeth made of nylon coil)

2. Gauge

The number of the gauge corresponds to the width of the zipper teeth, in millimeters, when the zipper is zipped. The larger the number, the more heavy duty the zipper.

  • The gauges we currently stock are:
  • #2 (Invisible Zippers Only)
  • #3 (Most common gauge for skirts and dresses)
  • #4
  • #4.5
  • #5 (Most common gauge for women's jackets and men's lightweight and medium weight jackets)
  • #7 (Antique Brass Zippers Only)
  • #8
  • #10 (For tents, sleeping bags, and heavy duty coveralls and men's coats)

3. Separating or Closed-Ended

There are two “bottom types” of zippers that we carry. Separating zippers have a pin and box at the bottom, allowing the zipper to separate fully into 2 pieces. An example of a separating zipper is a jacket zipper. Closed-ended zippers do not separate. An example of a closed ended zipper is a zipper in the fly of a pair of pants.

4. One-way or Two-Way – How many sliders (pieces that move up and down the tracks) are on the zipper.

Most zippers have one slider and are therefore one-way zippers. On the Zipper Shipper website, we simply refer to this as a zipper and don’t describe it as “one-way.” However, some zippers have two sliders and are therefore called “two-way zippers.” An example is a zipper on a longer jacket or coat, which can unzip from the bottom when the person wearing it is sitting down in order to allow room for their legs to move around more easily. Zippers for coveralls are often two-way zippers as well.

Note about 2-way zippers for bags or backpacks which have 2 sliders that open from the middle:

At this time, we do not carry ready-made zippers in bag-style configurations that have 2 sliders that open as you pull them away from the middle. However, you can create a zipper like that from our zipper chain by the yard and corresponding sliders. You would attach your sliders yourself in the configuration you wish to have. Nonlocking sliders are typically used for bags. You can use nylon or plastic zipper chain (nylon takes curves the best, but either are feasible). Here is a link:

5. Color

The color of the polyester fabric on the sides of the zipper.

6. Length

How long the actual opening of the zipper is.
