A 50mm solid brass padlock for a gate or a shed door that lives out in the weather, because brass doesn't rust the way a cheap steel lock does.
It's Master Lock's 150 with a hardened steel shackle 7mm thick and a 5 pin cylinder that's harder to pick than a budget lock. Dual locking levers hold the shackle in, so it resists prying and hammering too. The shackle is 25mm long and 25mm wide inside, which suits most shed hasps and gate chains.
It's keyed different and comes with its own keys. Full specs are in the tabs below, and if you need a few locks on the one key instead, call us on (08) 8536 4333 or pop in to 34-52 Milnes Rd, Strathalbyn.
