Weather-Resistant Extra-Clearance Resettable Combination Padlocks
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.

Weather-Resistant Key-Fob Padlocks
Padlock doors and other objects without worrying about the lock being picked or having to remember combinations. These padlocks unlock with a magnetic key fob. They have a brass body, which resists corroding from the weather. The stainless steel shackle resists rusting, but is easier to cut than other materials, such as boron alloy. Replace the shackle after damage or if you need a different vertical clearance.
