Squire Toughlok Lock & Chain Set offers excellent value for money. The chain, like the higher specification Squire chains, is hardened, so it is still a good choice for securing valuables. The chain is recommended for securing items within sheds when combined with a Squire wall or ground anchor. It is also recommended for securing garden furniture, barbeques, tool, and storage areas. As this chain is lighter than others in the Squire range, it is particularly suitable where the chain needs to be carried, for example, if used for locking a bicycle. Specification: Length: 900mm. Diameter: 5mm. Chain and Shackle Material: hardened mild steel. Lock Width: 38mm. Mechanism: 4-pin tumbler. Keyed-alike.
