About the 37RK/55HB75 GRANIT™ Padlock
A long shackle padlock handles hardware a standard lock can't even reach around. The 37RK/55HB75 GRANIT Padlock extends further than its siblings in the series, built for oversized hasps, thick chains, and layered gate fittings, without giving up the German engineering behind the GRANIT™ name.
ABUS 37RK/55HB75 GRANIT™ Padlock
This padlock secures halls, doors, gates, containers, and trucks holding goods at high risk of theft, with the longest shackle in the HB series for maximum reach. It meets European standard EN 12320 and features a coating built to fight corrosion over time. Hardened special steel forms the lock body and shackle, and an ABUS Plus disc cylinder sits inside to block manipulation attempts.
Tip: In combination with the Hasp 130, the protection is even more reliable!
One of the two included keys carries built-in LED lighting for dim conditions. A security card ships with the lock, and only a licensed ABUS dealer can cut a duplicate after verifying that card. Pair it with a heavy-duty hasp, or check our collection for chains sized to match.

Engineered in Germany for Extreme Security Demands
ABUS GRANIT™ padlocks carry a tensile resistance above 6 tons and rank among the most secure padlocks made anywhere. Premium alloy steel and precise manufacturing shape every lock in the series. Luminous keys and the black Granit™ coating set this line apart from ordinary commercial padlocks.
The ABUS-Plus disc cylinder pushes pick times far beyond what most intruders attempt. Chain the HB75 to construction equipment, gates, or a valuable vehicle for extended coverage. Looking for something lighter for indoor cabinets or lockers? Laminated padlocks fit that need well.
Oversized hardware needs a shackle long enough to close around it. 1st-in-Padlocks stocks the full ABUS GRANIT™ shackle range, along with heavy-duty hasps and chains built for warehouses, gates, and industrial equipment. Reach out to our team to find the shackle length that fits your hardware.
