What sets the ABUS 55/40 Twins apart

The Twins designation indicates two separate locking bolts, each operated by its own key — meaning a single key cannot open both locks simultaneously. This dual-lock mechanism significantly increases resistance against picking and unauthorised access compared to standard single-bolt padlocks.

Ideal for

Outdoor applications where weather resistance and tamper-proof security are essential — garden gates, storage sheds, utility lockers, and commercial fencing. The brass body withstands outdoor exposure without rusting, making it a dependable choice for year-round use.

Application of the ABUS 55/40 Twins

1. Insert the shackle through the hasp or loop on the gate or locker
2. Rotate the shackle fully into the lock body until it clicks
3. Use the key to engage both locking bolts simultaneously
4. Store the second key in a separate, secure location for backup access
