How is the 11 Line superior to other Grade 1 cylindrical locks?

The SARGENT 11 Line far exceeds the ANSI/BHMA A156.2 Grade 1
standard for cycle testing with virtually no lever sag after 15 million cycles!
The 11 Line also withstands more than 2 times the ANSI/BHMA A156.2
Grade 1 torque resistance requirements, resisting over 3,000 in/lbs of
excessive force.

This is an excellent choice for high use - high abuse applications.
