Common Zipper Problems Part 1, continued
Two-way zippers are very problematic and malfunction a lot. From a repair perspective, they are a big pain. The main reason they malfunction is people do not take the time to thread them properly. The sliders get misaligned and then forced which breaks the zipper.
This zipper was aligned properly. The male pins are evenly inserted at the bottom. One should be able to feel a discernible “click” when this is done right.
See how nicely it zipped up?
Same zipper, misaligned. Customer kept trying to zip it up like this, causing all sorts of problems. It doesn’t take much.
These problems are the same whether you have a tooth or coil zipper. Take the time to zip it correctly!
