The COSTUMAKERS Activewear Two Way Separating Zipper 70cm (28") - Sept. Brown - 1765 is engineered for activewear and outerwear requiring a reliable two-way separating closure. Constructed with #5 vislon molded teeth and medium weight tape, this zipper provides smooth, durable performance. The two-way design allows opening from either end, perfect for adjustable venting and effortless entry. To install, stabilize the zipper area with interfacing or stay tape, baste to confirm precise alignment, and topstitch close to the teeth using a zipper foot for accuracy. Test both pulls through the full length to ensure uninterrupted function. Select thread that matches for a seamless finish or contrast topstitching to highlight design details. Follow garment care instructions: machine wash gently, press over the teeth with a protective cloth to avoid heat damage. Always trim tape, grade seam allowances, and press each step to achieve professional results.
