Bolt Sleeve - An Important Safety Feature

Bolt sleeve is a safety feature commonly found in many household items, such as doors, windows, and locks. It serves as a barrier between the inside and outside, preventing unauthorized access to the interior of the item. Bolt sleeve is essential in ensuring personal safety and protecting property from unauthorized intrusion.

In addition to its security function, bolt sleeve also plays a vital role in preventing damage to items due to impact or impact shock. When a strong force hits an object, the bolt sleeve can absorb some of the impact energy, reducing damage to the object and reducing the risk of injury or harm to people nearby.

It saves time and effort, making it easier for people to protect themselves and their belongings from unauthorized access and theft. Therefore, it is essential to use bolt sleeve properly and regularly to ensure personal safety and protect property from unauthorized intrusion.
