Solid padlock for high-security access control

The Abus 37HB/55 KD is a hardened-steel padlock built for doors, gates and equipment cages that demand reliable physical security. Its square body measures 2 1/8 in wide and the long shackle provides 2 in of vertical clearance for thick hasps or chains. Seven-pin cylinder and a controlled keyway resist picking and unauthorised duplication. Weather-resistant finish suits permanent outdoor installation.

Long-shackle geometry resists leverage attacks

The 13/32 in diameter hardened-steel shackle extends well beyond the body, allowing the lock to engage oversized staples without exposing excess shackle to bolt-cutters. A single bumper cushions the shackle against the body during vibration, preserving alignment under repeated gate slam. Because the core is not interchangeable and the lock is not rekeyable, the keying remains fixed for the life of the unit, eliminating cylinder-swap bypass.

Hardened body and shackle shrug off cutting tools

Both body and shackle are hardened steel, so sustained sawing or grinding meets uniform resistance rather than a soft core. Black-and-silver coating rejects moisture and salt spray, preventing corrosion that could seize the mechanism. The 7-pin cylinder operates smoothly without lubrication in normal outdoor temperatures. No batteries, electronics or maintenance schedules are involved — mechanical security only.
