Tips & Features

Pick from features such as protective rubber covers, non-removable keys, and waterproof keys to ensure that you’re getting the best security possible.

  • The shackle is the metal fastening bar that opens and closes when the key is inserted or the proper combination is entered. Use a padlock with a long shackle in situations where a normal lock is too small to fit or in other unusual circumstances.
  • Padlocks with solid brass or thermoplastic bodies resist rusting and weathering. Aluminum bodies are lightweight and rust-resistant.
  • Die-cast zinc and solid-steel bodies and boron-steel shackles provide additional cut and pry resistance.
  • Hardened-steel shackle minimizes the chances of someone being able to cut through it.
  • Protective rubber covers and fitted plastic casings cover the lock and the surface of whatever it’s attached to protect from dents, scratches and the elements.
  • Padlocks with non-removable key features prevent you from walking away without securing the lock by not allowing you to remove the key if the lock is still open.
  • Waterproof keys prevent rusting and helps prolong the life of the lock by keeping the internal mechanisms working smoothly.
  • For car security, there are certain specially-designed locks that go over steering wheels and lock them onto place.
