Clearance and hasp compatibility

This model has shackle clearance C=25 mm, L=25 mm, and shackle diameter D=11 mm; Body width A=55 mm, thickness S=25 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

C3000 key system, supplied with Security Card; Replaceable cylinder, numbered key head. The cylinder protection plate is carbonitrided steel with electroless nickel plating.

C3000 is the key system for this entry. Even if another series has identical A/C/D/L/S dimensions, external dimensions do not establish key or cylinder interchangeability; Retain the series letters or numbers in the complete model.

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.
