Abstract
A conventional zipper is the preferred means for closure of many jackets and other outerwear. Conventional zippers are prone to jamming and snagging due to the introduction of the liner into the slider body as the zipper is opened and closed. Embodiments herein provide modified slider bodies with one or more features such as an elongated spring cap, a protrusion on the bottom plate and/or plate coupler of the slider body, and/or vertically offset side rails. These features may minimize introduction of loose fabric, such as the lining of a lined garment, into the tape slot of the slider body, thereby help reduce jamming of the slider body during operation of the slide fastener.
