Shackle locking on both sides

The catalogue explicitly excludes this model

Clearance and hasp compatibility

This model has shackle clearance C=12 mm, L=13 mm, and shackle diameter D=3.5 mm; Body width A=20 mm, thickness S=12.5 mm.

C is the clear width between the inner sides of the shackle, and L is the clear height beneath it; D describes the shackle bar diameter. Hasp hole diameter and spacing are different constraints; sufficient clear height alone does not establish that the shackle can pass through.

Keys, materials and construction scope

The catalogue also mentions an optional brass-shackle version, but this page records only the standard steel-shackle configuration in the table. Optional materials must not automatically be treated as the supplied specification for this order number.

This size is on the manufacturer's exclusions list for locking both sides of the shackle; it does not inherit this feature from larger sizes in the same series.

Limitations

• Catalogue dimensions are for preliminary selection; Product outline, opening clearance and supplied configuration follow the manufacturer's instructions for the corresponding model.
• The original diagram explains only the three measurement directions C, L and D; it does not show the actual lock-body outline, scale or protection grade.
