Is there a difference between the upper and lower sliders of two-way zippers? If the slider is broken and you want to change it, do you just need to buy two sliders with the same model and material?

There is a difference between the upper and lower sliders of two-way zippers. You don't just buy two sliders of the same model and material and then replace them. The upper slider cannot be used as a slider, but the upper slider is used as an upper slider. When buying, you should buy it according to the model. The specific differences are as follows:

1, different structures

In order to adapt to the structure of the pin and socket, the diamond-shaped column of the pull-down head is specially designed, and the height of the upper and lower openings in this part is also different from that of the upper and lower pull-ups.

2. Different sizes

The shape, width, angle and size of diamond columns are also different.

Two-way zipper using skills:

When pulling the zipper, you should first align the teeth on both sides, then hold the zipper head and gently pull it along the track. Don't use too much force to prevent the zipper from falling off the teeth.

Don't fill the zippered travel bag too full, so as to avoid the zipper from falling off its teeth.

Most zippers are made of aluminum alloy and can't touch alkaline or acidic substances.

The zipper doesn't close properly, often because the teeth on both sides of the nose are too loose. Just gently clamp the teeth of the nose with pliers and you can handle it.
