Zipper Measurements

ZIPPER MEASUREMENTS
The end use of a Zipper is also determined by its size /length and care should be taken while measuring it. This can be done (with the zipper closed) either:

·         From the bottom end of the bottom stop or the retaining box to the top of the slider

·         From the bottom end of the bottom stop or the retaining box to the top stop

·         Or from the end of the major portion to the tip.
