High-Security Padlock


S&G’s advanced high-security padlock meets US military specification MIL-DTL-43607J for perimeter security.

SKU: 951 Category: Tags: , ,


Designed to meet US military specification MIL-DTL-43607J, our Model 951 High-Security Padlock incorporates the most advanced features and materials available for perimeter security. Specialized barrier materials in the lock body and shackle resist cutting, drilling, and sawing, and a shrouded shackle design prevents wedging attacks.

Model 951 includes a restricted keyway locking cylinder available only to authorized government agencies, but Model 951C has a non-restricted cylinder to deliver the same advanced features for commercial applications.
