Factors affecting Safety Harness Buckles
1. The environment, whether the environment is good or bad, will affect the lock
2. Manual and proficiency will affect the production process of the lock
3. Machine and equipment precision, stability, durability
4. Material, the quality of the material determines the quality of the lock

The safety buckle is generally a hinged joint, which can only be opened inward, not outward, nor can it be opened. It is safe in theory. You can unhook the ring by exposing the hanging buckle. Then return to the original position to form a closed loop to complete the Lashing Buckles. Some have a spring automatic locking buckle, and a safer one also has a nut to prevent the hinge from accidentally sliding inward and causing the sling to loosen.
