Squire @Leisure Weathershield Combi CP40S

PRICE: £18.03

This variation on the CP40 has a stainless steel rustproof shackle and a double-locking 40mm die-cast lock body. It’s recommended by the manufacturers for marine use.

Like its @Home sister, the innards and the combination wheels had jammed solid with salt and corrosion after a stay in our tank, although the shackle was corrosion-free. It took 5 seconds to cut through with a pair of 18in bolt croppers.
