Master Lock Pro Series Stainless Combination Padlock
PRICE: £54.55
This is Masterlock’s new marine-grade combination padlock made from thick stainless steel, including all non-corrosive internal components. The most expensive on test, it has a plastic cover that hides the combination wheels.
After a month in the tank, there was a large amount of salty deposits around the numbered wheels, but this was just salt, not corrosion – and the wheels, made from stainless, turned well. I couldn’t get through the stainless shackle with the 18in bolt croppers, but it took only 30 seconds to get through with a sharp hacksaw blade.
