Notch Lock

This is a special only for the coil zipper.
It is so engineered that there is no lock in the slider to hold it to its place but the slider does not slide off completely at one stroke. The slider slips teeth of the zipper.
The slider mechanism is explained in the graphical clearly.
Failure can exist only in case of poor quality of the slider which is unfortunately in existence in huge majority.
The reason is due to lower awareness of the buyer & the undue advantage taken by other zipper supplier. None of them active interest in understanding the difficulties faced by a consumer/end user when the slider in bags or luggage or leather goods or other applications fail. This causes great problems for all the uses.
The critical zones of failure can be seen in the graphical.
At 3k, we engineer Notch lock sliders in a unique way so that there is absolutely no failure at all.
