The Masterlock Stainless Steel Shrouded Shackle Padlock is part of the Titanium Series, offering maximum strength. The 2-5/16in (59mm) wide stainless steel lock body comes with a No Rust Lifetime Guarantee. The hardened steel shrouded shackle provides extreme cut and pry resistance, making it 'Bolt Cutter Tough' and 'Crowbar Resistant'. A Weather Tough sliding keyway cover keeps dirt and grime from jamming the locking mechanism, while a scratch proof and durable ABS plastic bumper adds extra protection. The key retaining feature ensures the padlock is not left unlocked.
