How long a backpack will last depends on the quality of all its components. As a result of regular use, the lightning most often fails. The reasons are varied: poor quality of the original fittings, careless handling, moisture, dust, mechanical damage, wear...
Possible defects of zippers on a backpack
When a breakdown occurs, it is very important to determine the type of problem. The algorithm for further actions depends on this.
Lightning is a multi-component mechanism in which any element can break or become unusable.
Runner
If the lock has “lost” from the edges, most likely, parts of the slider have expanded. You can gently press it on the sides with pliers.
Important! You cannot repeat this procedure again, or squeeze the slider in the middle. This will lead to its final breakdown.
Prongs
If the lock is tightly fastened, it is enough to lubricate it on all sides with special compounds, a slate pencil, soap, or a candle.
The reason for the “divergence” of the metal zipper in the middle is damaged teeth.They need to be aligned and pressed by tapping with a hammer. If it falls out, replace it with similar ones, separating the teeth of a suitable size from another zipper and installing them in empty places.
If the zipper is plastic, a fishing line will help. In place of the fallen parts, we make stitches equal to the size of the teeth and secure them with a lighter.
Important! All of the above methods of resuscitating lightning help only temporarily. If none of the tried methods for correcting defects helped, you will have to change the entire lock.
Braid
If the zipper comes off the backpack, it is sewn on (preferably on a sewing machine). If the base is frayed and loose, strengthen it with molten plastic, Moment glue, and nail polish. The composition is applied, pressed, and allowed to dry.
Replacing a zipper
If these manipulations with the fastener do not help, the issue needs to be resolved radically. This means the lock will have to be replaced with a new one.
To maintain the functionality of the backpack, the work must be done efficiently and reliably. Therefore, the services of professionals will be required.
Reference! To ensure that the lock does not fail, you can replace it by contacting a tailoring shop, workshops, or shoe repair centers that provide metal repair services.
Here they will help you identify and quickly eliminate the entire range of existing defects. Professional craftsmen already have the necessary parts and equipment. This is especially important when working with leather and large backpacks.
The technician will remove the faulty fastener, select the fittings of the required size, and insert them into their original place.
The cost of replacing individual components is usually low, but the cost of replacing a complete lock is significantly higher. It includes the cost of fittings, the craftsman’s rate, and other expenses.
Reference! Specific prices and terms of work may vary significantly due to the complexity of the product cut, material, and the current workload of specialists.
Is it possible to replace the zipper yourself?
If you have the desire and appropriate practice, you can fix the zipper yourself.
Depending on the detected defect You may need improvised tools, a sewing machine, a new lock or its elements.
If the item is expensive, made of dense material (including leather), it is better not to experiment.
Important! Repair work on the backpack is characterized by limited access to the lock mechanism. Since it is securely sewn in or hidden by other parts of the accessory.
In such conditions, it is problematic to perform the replacement correctly and accurately. A household machines do not have the same sewing ability as industrial ones. It is better to entrust your choice to professionals who have experience and special equipment!
