Robust and rust-free. The Abus 180IB marine combination lock is the perfect solution for outdoor use. The Abus 180IB combination lock is excellent for securing medium-value items and possessions with an average risk of theft. A body made of forged brass and a shackle made of stainless steel make the Nautilus 180IB/50 a combination lock that is equipped to withstand wind and weather. Especially in the face of strong weather and environmental influences, such as when used in maritime and harbor areas or for securing vehicles and boats in outdoor settings, the lock demonstrates its strengths.
