HOW TO MEASURE A ZIP LENGTH
| Classification | Dimensions (A) | Dimensions of top tape extension (B) | Dimensions of bottom tape extension (C) |
|---|---|---|---|
| Closed-end zipper | From the top end of the slider to the tip of the bottom stop | From the top stop to the tip of notches of the cut end
|
From the top stop to the tip of notches of the cut end |
| Zipper with double sliders (arranged in head-to-head relation) | From the tip of one bottom stop to the tip of the other bottom stop | From the upper bottom stop to the tip of notches of the cut end
|
From the tip of the bottom stop to the tip of notches of the cut end |
| Zipper with double sliders (arranged in bottom-to-bottom relation) | From the top end of one slider to the top end of the other slider | From the top stop to the tip of notches of the cut end
|
Same as the top tape extension end portion |
| Open-end zipper | From the top end of the slider to the tip of the box | From the top stop to the cut end
|
|
| Two-way separator from the top | From the top end of the slider to the bottom end of the supplementary tape | From the top stop to the cut end
|
|
| Top open zipper | From the top stop to the tip of the box | From the top stop to the cut end
|
|

TECHNICAL INFO
NOTE
- Close the zipper until the slider completely touches the stop to ensure tightness.
- When opening or closing, always ensure that the direction of the pull is along the line of the metal teeth. When closing, ensure that both sides of the open zippers are parallel. It is very important to avoid catching undergarments in the teeth. If the slider should jam during closure, DO NOT FORCE IT. Pull back the slider, remove the obstruction and slowly attempt to close it again. Excessive force will break the metal chain and destroy the fastener. Also avoid bending the zipper excessively as this will eventually cause the metal chain running inside of the fastener to break.
- As for PVC tape, do not use in an environment where the water temperature is under 10 degree C, as the PVC will become hardened, and it will affect the fastener’s performance.
- Due to the characteristics of PVC, its tightness will deteriorate over time.
- After using the zipper, it should be rinsed in clean water. Any objects (sand, mud, etc.) found in or outside of the elements before operating the zipper may result in poor tightness or may damage the zipper.
- Do not dry clean, machine wash or iron.
- Occasional cleaning and lubrication of the elements after use is desirable. Such treatment is especially important if PROSEAL® zipper is used in a dirty or corrosive environment. After rinsing with fresh water, please apply a lubricant, such as paraffin lightly to the part circled in red in the picture below in the elements. After opening and closing the zipper several times, excess paraffin flakes should be removed.
- Store with the zipper completely open, taking care not to bend it. Storage of the zipper in a closed position for long periods will cause malformation of the sealing areas. Also, storing partially opened will cause zipper bending. If these effects occur, slight leaks are possible.
- Do not place any heavy object on the zipper.
- Prolonged contact with such surface materials as PVC or synthetic leather, cause the PVC to react with their processing additives and cause a color migration (color transfer) to occur. Avoid direct contact when storing by placing a sheet of paper between the zipper and the material.
