This is a YKK reverse coil slider in the non-locking style, size #3, made for reverse coil zippers like the AquaGuard, where the coil sits on the back and the smooth, weather-facing side shows on the outside. Running the correct reverse slider is what keeps that clean outer look and lets the zipper close the way it should. Non-locking means the slider glides freely and stays wherever you leave it, with no internal pin holding it in place. It's the easy-moving choice for pockets, pouches, and openings that don't sit under constant tension, and it tends to feel a touch smoother than a locking slider. If you'd rather the slider hold firm under load, the locking version is the one to reach for. Use it to finish a length of AquaGuard zipper by the foot in #3, or to replace a worn or broken slider without swapping the whole zipper. You can also browse all reverse coil sliders for other sizes and styles. Bulk pricing is available for larger runs, with no minimum order for a single repair.
