How to Repair a Zipper With Two Sliders — FixnZip®
double zipper

Posted by & filed under Zipper Repair.

A lot of people have been emailing me lately asking how to fix a broken double zipper and if the FixnZip will work on that type of a zipper. First off, a double zipper has two sliders on the same zipper track that can open the zipper from either end. You can find a double zipper on items like jackets, sleeping bags, and tents. Sometimes the two sliders meet in the middle and sometime the two are flush and zip away from each other. In short, the FixnZip works on these types of zippers and can be used to repair them. I’ll walk you through why the problem occurs and how to repair. If you don’t like reading, just scroll down to the video.


Why isn’t the zipper working?

Usually, a double zipper will stop working because the one or both of the sliders has worn down or broken off. You can tell there’s a problem with the zipper sliders when the teeth won’t stay connected. And if one of the sliders on a double zipper is broken or has popped off, then the zipper isn’t functional until you replace the broken zipper slider.


How can I fix it?

You can always have a seamstress repair the broken zipper, but then you’ll pay a premium for fixing an especially complicated zipper, not to mention the time it would take. Or you can use the FixnZip as the replacement zipper slider for one or both sliders on the double zipper. It doesn’t require any tools or sewing, and you can fix your broken zipper in a matter of minutes.


I put together a short video to show you how. I use a jacket to demonstrate, but it’s the same process on any item with a broken double zipper.



If you can’t watch the video, you can find instructions here on our website or on the insert that comes with the FixnZip. The only difference is that, if both zipper sliders are broken, you’ll put the top FixnZip on right-side up, and the bottom one on upside down. Then you feed the other row of teeth through both sliders, just like you did before it was broken.


What size FixnZip should I get?

The FixnZip comes in small, medium, and large, and these three sizes work for just about any zipper out there. A double zipper is usually found on jackets, bags, tents, and sleeping bags, which all use a size medium, but take a look at our sizing guide to be sure. The FixnZip also works on any type and material: tooth or coil zippers in metal, plastic, or nylon. Whatever your zipper, FixnZip can repair it.
