On a chain that has come off one side, the teeth on that side will be sitting outside the slider rather than running through it.Check the slider itself from the side. If the top and bottom plates have spread apart, that gap is the actual fault, not the teeth."},{"number":2,"title":"Step 2: Get Your Parts Together","text":"You need a pair of needle nose pliers and, if you are replacing rather than reusing, a slider that matches your zipper size and a new bottom stop.Zipper sliders are sized. A number 5 slider will not run on a number 3 chain, and the size is usually stamped on the back of the old slider."},{"number":3,"title":"Step 3: Open the Slider a Fraction More","text":"The slider has already sprung open, which is why the zipper failed. Ease it open a little further with the pliers so there is room to get the chain back inside.Go gently. On an older bag the metal has fatigued, and it will snap if you lever it hard."},{"number":4,"title":"Step 4: Feed the First Side In","text":"Angle the slider so one channel lines up with the end of the chain, and work the teeth in a few at a time.The tape wants to fold. Keeping it flat and pulling from beyond the slider rather than pushing at it makes the teeth track properly."},{"number":5,"title":"Step 5: Feed the Second Side In","text":"Now do the same on the other channel. This is the fiddly one, because the first side is already in and gets in the way.Hold the slider still and bring the chain to it. Moving the slider along the chain you have already threaded will just pull the first side back out."},{"number":6,"title":"Step 6: Line the Two Sides Up","text":"With both sides through, check the chain is even. If one side is puckered or sitting higher than the other, hold the slider and pull the tape until the teeth line up level.Then run the slider all the way to the closed end before you do anything else. Pinching it shut halfway along leaves you with a zipper that only works from the middle."},{"number":7,"title":"Step 7: Pinch the Slider Closed","text":"Take the needle nose pliers and squeeze the top and bottom of the slider back towards each other. That closes the clamshell gap that caused the failure.Small squeezes, testing as you go. Overtighten it and the slider will seize solid on the chain."},{"number":8,"title":"Step 8: Test the Full Run","text":"Run the slider from one end to the other a few times. It should close the teeth cleanly behind it and not separate.If the zipper still pops open, the slider needs another small pinch. If it now sticks or drags, you have gone slightly too far and need to ease it back open a fraction."}],"recipe":null,"lastUpdated":"2026-08-21T15:31:39.923Z","published":"2026-08-21T15:31:33.798Z","license":"CC BY 4.0.
