Two-way separating zippers,sometimes called dual zippers, double zippers, or two-head zippers, separate at the bottom, jacket-style. They have two sliders, unzipping from the top down, or the bottom up. Jeep zipper is designed to replace Jeep Wrangler soft top zip-out rear window zippers, which use a #10 coil zipper. The zipper chain opens from both ends, and is fully detachable on one end. The handles on the sliders are teardrop shaped, longer than the originals for more leverage, but do not come with the cording string. The zipper tape is extra-wide for easier installation.
They are also useful for tents, as you can circulate air more easily than with a one-way zipper. 2-handled sliders allow zipping from either the inside of the structure or the outside of the structure.
