Abus Weatherproof Combination Padlock 180IB/50

PRICE: £31.93

This 53mm padlock has a stainless steel 8mm shackle and is described thus: ‘This model is designed using a stainless steel shackle and noncorrosive internal components for added environmental protection. It is therefore also highly secure and resistant to force attacks.’

After a month in the test tank, its brass body was suffering some pink dezincification and the moveable parts had salt build-up, but after a rinse the wheels and shackle moved as before, albeit with some corrosion. It was fairly resistant to force, being impervious to the 18in bolt croppers, and taking 20 seconds to cut through the stainless shackle with a sharp hacksaw.
