Building and reliability are the main considerations when choosing cylindrical locks. Schlage and Falcon are two of the best-known lock manufacturers.

Medium duty locks are designed for use in commercial exterior applications that don’t require rigorous security and for interior doors of medical offices, hotels, retail stores, public facilities, churches and apartment buildings.

Heavy-duty cylindrical locks provide security in exterior and interior applications for industrial facilities, schools, hospitals, offices, retail stores, government/public office buildings and factories.
Cylindrical locks are usually available in both lever or knob designs. Lever locks should meet ADA requirements. Additional options include special finishes to help users identify by touch that the lock leads to a space containing hazardous materials. The best locks include a feature that allows the exterior knob or lever to move freely even when locked; this helps prevent intruders from breaking the lock. When purchasing locks for fire doors, make sure the lock is rated for use on a fire door.
