Clearance and hasp compatibility

This model has shackle clearance C=27 mm, L=39 mm, and shackle diameter D=9.5 mm; Body width A=55 mm, thickness S=27.5 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 body accepts a 30/10 mm Euro-profile half cylinder, which must be purchased separately. Compatibility examples listed in the catalogue include Asix 1.0E304.02.0, C2000 1.0G304.02.0 and C3000 1.0N314.02.0; Similar appearance alone does not establish compatibility with an arbitrary cylinder.

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.
