Your gear box lock is rusting shut, the padlock on the boat trailer has seized, or you just need a small, reliable lock that won't flake apart after one season of salt air. This Jaycar 30mm padlock is cut from 304-grade stainless steel and made specifically for the marine environment. It's compact enough for a locker, a small hatch, or a gear box, and it comes with three keys so you're not chasing a single key around the boat. No gilding, no mystery alloy – just 304 stainless that handles spray, salt, and UV without turning to orange powder
