Additional Information
- Extended shackle padlocks provide reach but expose more shackle than standard versions.
- Choose the shortest shackle that comfortably fits your locking point to minimise attack exposure.
- Keyed alike configurations simplify access management across multiple locks.

Choosing the Right Shackle Type
- Standard Shackle
Fixed-length shackle with balanced clearance and strength.
Best for: lockers, cabinets, toolboxes, general-purpose indoor and sheltered use.
Why choose it: shortest exposed shackle gives better resistance to cutting and prying. - Long Shackle
Extended shackle provides additional vertical reach through deep or offset fittings.
Best for: chains, gates, deep-set hasps, awkward or recessed locking points.
Trade-off: increased reach comes with increased shackle exposure. - Concealed Shackle (CS)
Shackle is partially enclosed within the lock body to minimise attack points.
Best for: shared lockers, cabinets, and higher-risk applications.
Why choose it: significantly reduces vulnerability to bolt cutters.
Guidance: Always choose the shortest shackle that comfortably fits your locking point. Reduced shackle exposure improves resistance to cutting and levering attacks.
