The SARGENT & GREENLEAF 951C is the ultimate padlock for commercial applications where security trumps everything else.  This indoor/outdoor padlock includes a Medeco biaxial key cylinder.  Locksmiths recommend the Medeco cylinders because of their ability to resist picking.  For this reason alone, the S&G 951 is the best choice for a padlock solution in locations where a forced attack could happen, but that's not all. Unlike a generic padlock where you can drop it and the shackle will crack, the 951C (p/n: 951-009) comes with a stainless steel body, dual stainless steel ball locking mechanism, and special hardened shackle.  You'll notice the clear opening which lets you operate the shackle with ease.  You can see too it is shrouded.  This increases the level of security against 'wedge' attacks.  Modeled with cutting-edge security features you would be hard pressed to find in any other padlock in the world, the SARGENT & GREENLEAF 951C uses special barrier materials inside the padlock body and shackle to assist in thwarting a cutting or sawing attack.  SARGENT 951C commercial padlocks are an upgrade to the trusted legacy SARGENT 833 padlock.  The new 951C offers an even higher level of security than its predecessor. About SARGENT & GREENLEAF Delivering advanced security solutions since 1857, SARGENT & GREENLEAF makes safe locks, padlocks, and many more security devices which serve to protect individual homeowners up to the highest levels of government, and anything in between.

    A Product specifications of this caliber are not outlined or defined. You can, however, talk to the manufacturer direct and see if this is something that this lock can handle. Please give our technical staff a call at 937-247-9327 option 3 for support and information.

    The 951C is for local distribution and the government does purchase them and swap out the cylinder to their restricted cylinders, however, to purchase the specific MIL-DIL-43607J version you must go through the DOD as those are sold by the manufacturer directly to the DOD with the specified restricted cylinder already in place.
