A 40mm padlock is a padlock where the width of the padlock body measures 40 millimeters.
Essentially, this measurement refers to the horizontal dimension of the main body of the padlock itself, often the widest part. This dimension is typically used to categorize and differentiate padlocks based on their size and intended security level. Larger body widths generally indicate a more robust lock with a thicker shackle.
Understanding Padlock Dimensions
While the 40mm designation refers specifically to the body width, it's useful to understand how other dimensions relate to the overall size and security of the padlock. Common padlock dimensions include:
- Body Width (A): The width of the main body of the padlock. In this case, it's 40mm.
- Shackle Diameter (C): The thickness of the metal shackle that loops through the item being secured. A thicker shackle generally provides more resistance to cutting. The shackle diameter usually corresponds to the body width, with larger body widths often having thicker shackles.
- Vertical Shackle Clearance: The internal vertical height of the shackle when the padlock is open. This determines the size of the object that can be secured.
- Horizontal Shackle Clearance: The internal width of the shackle when the padlock is open.
A 40mm padlock offers a balance between size, security, and versatility for various applications.
