How do chain locks perform in terms of waterproofing and dustproofing?

1. Product Labeling:

From the chain lock images and descriptions provided by NINGBOJINTA, no IP protection rating (such as IPX4, IP65) or waterproof/dustproof markings were found. The outer layer of the chain is a fabric protective cover, which can prevent dust adhesion to some extent, but the fabric itself is not waterproof.

2. Metal Lock Body:

The lock head is made of carbon steel or heat-treated steel. If exposed to a humid environment for a long time, the metal surface may corrode, especially for lock bodies made of non-stainless steel.

Electronic fingerprint locks (such as JT0907) are more sensitive and lack waterproof and dustproof design. Rain or high humidity environments can easily cause water ingress and malfunction of electronic components.

3. Usage Recommendations

Avoid prolonged exposure to damp environments: In rainy seasons or humid areas, it is recommended to install a waterproof cover on the lock body or use waterproof tape for secondary protection.

4. Regular Maintenance

Treatenate the metal lock body for rust prevention (such as spraying rust-preventive oil or using rust-preventive paint) and keep the lock body dry.

Select products with appropriate protection levels: If the environment has specific requirements for waterproofing and dustproofing, consult the supplier about upgraded chain locks with IPX4 waterproof or IP5X dustproof ratings (refer to common industry protection level specifications).
