Additional Information
- The S&G 6730 is widely regarded by professional safe technicians as a “fit and forget” lock, often remaining in service for decades without internal component failure.
- Mechanical combination locks such as this are commonly specified in environments where electronic failure, battery management, or electromagnetic interference is unacceptable.
- The patented torque adjuster contributes to a firm, consistent dial feel, helping reduce wear-related combination drift over long service life.
- Once the integral relock trigger is activated during an attack, the lock cannot be opened conventionally and typically requires destructive entry, increasing attack time and noise.
- The non-handed design allows the same lock model to be used across multiple safe orientations, simplifying inventory for safe manufacturers and service technicians.
