  • Save money. Buy less locks. Minimize cut lock shackles.
  • Value added. The Lock Guard to protect your shackle is at a fraction of the cost of more expensive locks, at a low cost versus locks with shoulders that protect only a part of the shackle, or the cost of thicker shackles purchased to prevent thieves from cutting locks. Fight those who cut locks or cut padlock.
  • Weather protection. Customers in various climatic conditions declare benefits of a shackle cover or 'house' over their lock. This helps protect the lock from the elements - snow, rain, dirt, salt spray - that can shorten a lock's usable life.
  • Commercially produced. For government approved lock guard for explosives & fireworks, contact ATF or us for details.


  • Ranger® Lock Guards are fully portable with easy installation in seconds and can be stored as one unit with the lock.
  • They are interchangeable between locks and universal; fit most brand locks or most commercial locks such as Master Lock, Abloy padlocks, and others .
  • Made of hardened steel, the guards are corrosive resistant and are installed with no bolts and no welding.
  • Angled roofs on swing door lock guards to deflect, deter, or hamper physical attack or blows

Protect Your Lock
When you decide to guard your lock with one of our hardened steel door lock guards, you’re ensuring your lock lasts longer and holds up better to what the world throws at it. Whether you use one of our shackle-free hockey puck locks or a regular padlock, our lock guards are guaranteed to protect your locks — and your valuables.

When you use a padlock protector box over your padlock, you’re protecting it from thieves with bolt cutters, crow bars and other tools. A padlock protector also safeguards your padlock against rain, sleet, snow, salt spray and dirt that could weaken it and shorten its life. Our padlock protection boxes have sloped roofs so snow and ice slide ride off — and so do thieves’ blows.

Best of all, our padlock guard systems are easy to install and can be removed and stored as one unit with the lock inside. Our padlock protector box fits most brand-name commercial locks. No matter what lock you use, you can rest assured our padlock guard will protect it.
