You've got a locker on the wharf, a gear box at the boat ramp, or a utility shed that keeps getting 'borrowed' by whoever walks past. You need a lock that actually locks, sits flush so it doesn't stick out, and won't turn to orange rust by next summer. This Jaycar round flush latch is simple key-lockable – one key in, one key out, no fiddly mechanism.
