How to repair a suitcase or luggage zipper using ZlideOn
A suitcase zipper that splits open behind the slider, or a pull that has snapped clean off, doesn't mean the case is finished. In almost every instance the slider is the part that failed — and replacing it takes a couple of minutes, with no sewing and no luggage repair shop.
Get the right ZlideOn for your suitcase
First things first! Check the number printed on the back of your old slider, or measure the width of the zipper teeth, and pick the ZlideOn that matches. Luggage almost always uses coil zippers. Cabin bags, laptop compartments, and interior pockets are usually size 5, while large hard-shell and check-in cases often run to size 8 or 10.

Carefully snap off the broken slider
Grip the old slider with a pair of pliers and snap it off the zipper chain. On luggage the two sliders usually meet in the middle of the case, so run them to one end first, past the stopper, where you have room to work.
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.
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. Run it right around the case a couple of times to bed the coil in — your suitcase is repaired, pull and all.

Important things to remember
A broken zipper pull and a broken slider are usually the same repair. The pull is the little tab you hold; the slider is the metal body it hangs from. When a pull snaps off, the slider underneath is normally worn too — which is why replacing the whole slider fixes the problem properly rather than threading a paperclip or keyring through what's left.
ZlideOn replaces the slider, not the zipper chain itself. Check the coil and the tape stitched into the case before you start: if teeth are missing or the tape has torn away from the shell, the case needs a luggage repairer. Far more often the slider has simply spread from being forced over an overpacked bag, which is exactly why the zipper splits open behind it.
Getting the size right matters. Check the number printed on the back of your old slider or measure the width of the coil before ordering. If you're unsure, a multipack covers the most common sizes and is the safe choice. Most suitcases run two sliders on one chain — replace both if the second one is also loose, since they wear at the same rate.
Why repair your suitcase instead of buying a new one?
A suitcase shell will normally outlast several sets of zipper sliders, and a case is a poor thing to throw away over a part the size of a coin. Replacing the slider with ZlideOn takes minutes, costs a fraction of a new case or a luggage repair, and needs no sewing or specialist tools. Made in Europe from durable zinc and steel, a ZlideOn slider handles being hauled through airports as well as the case does.
Repair, don't replace. Luggage is bulky, hard to recycle, and made almost entirely from plastics. Keeping a case in service saves all of that — and with ZlideOn, it's one of the easiest sustainable choices you can make.
