Designed for outdoor commercial use, these rekeyable padlocks will stand up to severe abuse and severe weather. Boron alloy steel shackles repel saws and bolt cutters. Dual locking shackles resist forcing or prying, and special pick resistant spool pins prevent unauthorized entry. Durable thermal plastic cover protects lock body and key cylinder from dirt, dust, and other contaminants. Special drain channels move water and other debris through the lock body and away from the lock mechanism.
