Under Federal Specification FFL-2937, which statement is accurate?

• A. Only the S&G 2740 is approved for use as a mechanical combination lock.
• B. No mechanical combination locks are approved under the specification.
• C. The S&G 2740 is not approved for use as a mechanical combination lock.
• D. There are multiple models approved for use as a mechanical lock, not only the S&G 2740.

Answer: (D)

This item tests recognizing that federal specs sometimes approve more than one device for a given category. Under this specification, the approved list includes several mechanical combination lock models from different manufacturers, not just one. That means the correct statement is that there are multiple models approved, not only the S&G 2740. The S&G 2740 is one example, but the standard allows other models as well, providing options for procurement and compatibility.
