The COSTUMAKERS Activewear Two Way Separating Zipper 80cm (32") - Black - 1765 is engineered for garments requiring a reliable two-way separating closure. Constructed with #5 vislon molded teeth and medium weight tape, this zipper delivers smooth, durable performance. The two-way design allows opening from either end for adjustable venting and effortless entry. To install, stabilize the area with interfacing or stay tape, baste to confirm alignment, then topstitch close to the teeth using a zipper foot. Test both pulls through the full length to ensure seamless functionality. Choose matching thread for a discreet finish or contrasting topstitching to highlight design lines. Machine wash gently per care instructions, pressing over the teeth with a protective cloth to avoid heat damage. Always trim tape, grade seam allowances, and press each step for professional results. Stock a variety of colours and lengths to support repairs, custom fittings, and new designs.
