Veto brass padlocks have a rubber shackle seal to prevent water ingress. They have a hardened steel shackle for extra protection against hacksaw and cropping attacks. The solid brass body is to enhance corrosion resistance and they have a double locking brass cylinder which also provides extra protection against attack. NB: On 30mm brass padlocks there is no rubber seal to the shackle and the shackle is not hardened. Brass padlocks come with a security rating of 3-6 and a weather rating of 3/5.
