What this cylinder fits

The Medeco 20-200H1-605-00 is a key-in-knob and lever replacement cylinder finished in Bright Brass 605. It is designed to retrofit Arrow and Schlage lock sets using the 00 Keyway for residential or light commercial doors.

Security standard that matters

This cylinder carries a UL-437 listing confirming it meets universal benchmarks for drill and pick resistance. Solid brass construction supports the high-security rating and provides a large number of key combinations.

Installation notes

The cylinder installs into existing knob or lever hardware without replacing the full lock set. Compatibility depends on matching the 00 Keyway and manufacturer prep; cylinders with different keyways or tailpiece lengths will not operate correctly.

Questions about this item

What does the UL-437 listing mean for daily use of this cylinder?

The UL-437 listing confirms the cylinder meets universal standards for drill and pick resistance, so it resists common forced-entry attacks on a daily basis.

How does the 00 keyway affect which keys work with this cylinder?

The 00 keyway means only keys cut to that specific Medeco profile will operate the cylinder, preventing use of standard Arrow or Schlage keys.

What door thickness or lock prep does this cylinder need to fit?

It is designed as a key-in-knob or lever retrofit for many manufacturers, fitting standard cylindrical lock preparations without modification.
