Squire @Home Weathershield Combi CP40

PRICE: £18.03

This small combination lock has a hardened steel 6mm-diameter shackle and a double-locking 40mm die-cast body, and is described as ‘all-weather’.

After a month in the salty environment of our tank the combination wheels had seized up and stopped turning, and the hardened shackle was seeping rust. It took 6 seconds to cut through the shackle with a pair of 18in bolt croppers.
