High-Security Lever Cylinder

The Medeco 20-200A1-605-00 is a key-in-knob lever cylinder finished in bright brass. It carries a UL-437 listing confirming drill and pick resistance standards. Solid brass construction provides durability for long service life. This cylinder suits commercial and residential doors requiring high-security retrofit hardware.

Verify Lock Compatibility

Confirm the existing lock set accepts a key-in-knob or lever cylinder of this design before ordering. The 00 keyway must match the facility's current key system for proper operation. Ensure the bright brass 605 finish aligns with the surrounding hardware aesthetics. Check that the cylinder length suits the door thickness and trim configuration.

Retrofit For Arrow Hardware

This cylinder replaces original cylinders in Arrow knob and lever lock sets without modifying the chassis. The upgrade is worthwhile when UL-437 drill and pick resistance is required for insurance or code compliance. It also benefits sites needing the expanded key combinations of the Medeco system. The solid brass body outperforms standard zinc or plated cylinders in high-traffic applications.
