2. Tape – This is the fabric on either side of the zipper teeth. It is usually made of polyester. This is stitched to the fabric to attach the zipper
3. Pull and slider – This is the metal/plastic piece which opens and closes the zipper teeth by moving along the teeth track. The pull is used to move the slider
4. Stopper – this is the metal thing at the edge of the zipper teeth which stops the zipper teeth from separating fully. There are stoppers on top of the teeth and at the bottom
( For a seperating zipper, instead of a bottom stopper there is a box and pin mechanism which closes the zipper and slides it open)
