What diameter must a high security or casehardened padlock bow have at minimum?

A high security or casehardened padlock bow must have a minimum diameter of 3/8 inch to ensure sufficient strength and resistance to cutting and forced entry attempts. The bow is the part of the padlock that connects the shackle to the lock body, and a thicker diameter enhances the overall durability and security of the padlock. A diameter of 3/8 inch strikes a balance between providing adequate security without compromising functionality, allowing for use with various locking mechanisms while resisting tampering or damage.

Higher diameters, while potentially offering more security, may not be practical for many applications, whereas a diameter less than 3/8 inch would significantly weaken the padlock, making it more vulnerable to attacks. In this context, understanding the right specifications for security devices helps ensure better protection and resilience against unauthorized access.
