Reverse coil isn't a different zipper. It's the same coil chain, run with the slider on the opposite face so the coil sits on the inside and the clean tape face shows outward. That's the look you see on pack lids and bike bags, and it keeps the coil away from whatever the zipper rubs against. What does change is the slider. A reverse coil slider is shaped to sit on the other side of the chain, so it isn't interchangeable with a standard coil slider. This one fits #5 chain. Non-locking means it runs freely and won't hold position on its own, which is what you want on two-way setups and pockets that need to open smoothly. Most builds pair it with a cord or fabric pull. Black oxide gives a matte finish that doesn't glare or show wear the way bright metal does. Sold individually with no minimum order, so you can grab one for a repair or stock up for a production run.
