The 30mm lock was a tight squeeze on your locker hasp, or you need a bit more shackle clearance for a thicker gate or a boat trailer latch. This Jaycar 40mm padlock steps up the size while keeping the same marine-grade 304 stainless steel build. It's made for salt spray, UV, and the general abuse of outdoor Australian use. Three keys come in the box, so you can hand one to the partner, one to the mate who helps with the trailer, and keep one in your pocket. No mystery alloy, no flaking paint – just 304 stainless that does its job season after season
