Vertical shackle clearance is greater than 1". These corrosion-resistant padlocks are well suited for refineries and marine applications. Set your own combination and change it at any time.
Brass-body locks are the most corrosion resistant. Epoxy-coated hardened steel body locks are the strongest lock body and are coated for corrosion resistance. Stainless steel body locks have very good corrosion resistance and are stronger than zinc-body and brass-body locks.
Locks with hardened steel shackles are more cut resistant than locks with stainless steel shackles. Boron-carbide shackles are the most cut resistant.

These padlocks won’t corrode when exposed to harsh weather and open with a magnetic key fob instead of a traditional key or combination, so they can’t be picked. Tap the key fob on the front of the padlock’s body and pull the body away from the shackle to unlock. All padlocks have a brass body and a removable shackle, which lets you replace a shackle if it’s damaged, or swap it out for a different vertical clearance or material.
Stainless steel shackles are more corrosion resistant than boron alloy shackles. They are not, however, as cut resistant.
Boron alloy shackles are harder to cut than stainless steel shackles, but are not as corrosion resistant.
