Clearance and hasp compatibility

This model has shackle clearance C=33 mm, L=14 mm, and shackle diameter D=10 mm; Body width A=66 mm, thickness S=22.7 mm.

C and L are the two clearance directions of the recess beneath the straight shackle. When checking the hasp, also verify whether the straight shackle can pass through its opening and whether there is enough clearance around the lock body; do not select solely by external body width.

Keys, materials and construction scope

This series has a brass body with external hardened-steel armour, differing from a solid-steel body. Shackle passes transversely through the recess; check both recess clearance and shackle diameter when selecting.

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.
