Frequently Asked Questions

What makes Sargent knob locks institutional-grade?

Sargent knobs feature Grade 1 certification, patented clutch mechanisms preventing forced entry, cycle testing exceeding industry standards, and integration with Sargent's high-security keying systems.

When should I specify Sargent knob locks?

Sargent knobs excel in high-security storage, evidence rooms, pharmaceutical areas, IT closets, and facility infrastructure requiring premium protection without ADA lever requirements.

Can Sargent knobs be master keyed?

Yes, Sargent knobs support interchangeable cores (LFIC/SFIC), patented keyways with utility patent protection, and complex master key hierarchies available through National Lock Supply.

What is Sargent's clutch technology in knob locks?

Sargent's clutch allows the exterior knob to rotate under force without retracting the latch, preventing forced entry while protecting internal mechanisms from damage during attacks.

Are Sargent knobs suitable for healthcare facilities?

Yes, Sargent manufactures knobs meeting healthcare durability requirements for utility and mechanical spaces, though lever locks are required for patient-accessible areas.

Do Sargent knobs work with existing door prep?

Sargent cylindrical knobs fit standard ANSI 2-1/8" bore prep, while mortise knobs use standard mortise pockets. National Lock Supply can advise on retrofit applications.
