How to repair a zipper slider or pull using ZlideOn
When a zipper stops working, the chain of teeth is almost never the problem — the slider is. It wears wide, stops locking the teeth behind it, and the zipper splits open or refuses to close. Replacing that one part takes a couple of minutes and works the same way on a jacket, a bag, a tent, or a pair of boots.
Get the right ZlideOn for your zipper
First things first! Check the number printed on the back of your old slider — usually 3, 5, 8, or 10 — or measure the width of the zipper teeth, and pick the ZlideOn that matches. If you can't read the number and aren't sure how to measure, a multipack covers the most common sizes in one go.

Carefully snap off the broken slider
Grip the old slider with a pair of pliers and snap it off one end of the zipper chain. Work past the stopper where the chain is easiest to reach, and go slowly so you don't damage the teeth underneath.
Fully open your ZlideOn
Hold the ZlideOn between your fingers and open it up completely, so the two halves are ready to sit around the zipper chain. The patented hinge does the work — no tools needed for this part.
Click it onto the zipper
Place the open ZlideOn over the zipper teeth and press both sides firmly together until you hear it click shut. Zip at least 10 cm on the first pull to align the teeth — your zipper is repaired.

Important things to remember
A broken zipper pull and a broken slider are the same repair. The pull is the tab you hold between your fingers; the slider is the metal body it hangs from. When a pull snaps off, the slider underneath is usually worn as well — which is why fitting a whole new slider fixes the zipper properly, rather than threading a keyring or paperclip through what's left of the old one.
ZlideOn replaces the slider, not the zipper chain itself. Check the teeth and the fabric tape before you start: if teeth are missing or the tape has torn away, the item needs a tailor or repairer. In the large majority of cases, though, the slider is the only thing that has failed, because it's the part that does all the moving.
Getting the size right matters more than anything else in this repair. The number on the back of the old slider is the quickest guide; failing that, measure the width of the closed teeth. Zippers also come in different shapes — metal, plastic moulded, coil, and waterproof — so match the type as well as the size. If you're unsure on either count, a multipack is the safe choice. Fit the ZlideOn on the side of the zipper carrying the larger part of the stopper, and if it skips or won't close cleanly after the first 10 cm, open it, reseat both rows of teeth, and press it shut again.
Why repair a zipper instead of replacing the item?
A zipper slider is one of the smallest parts on anything you own, and it fails long before the item around it does. Replacing it with ZlideOn takes minutes, costs a fraction of a replacement garment or a tailor's bill, and needs no sewing, tools, or specialist skill. Made in Europe from durable zinc and steel, a ZlideOn slider is built to outlast the one it replaces.
Repair, don't replace. Every item kept in use saves the CO₂, water, and raw materials that go into producing a new one. Choosing to repair is one of the simplest, most effective sustainable choices you can make — and with ZlideOn, it's also one of the easiest.
