Medeco Rim Cylinder Lock

The Medeco 10-0300-605-00 is a high-security rim cylinder designed for use with auxiliary rim locks such as surface-mounted deadbolts, night latches and Jimmy proof locks. It features solid brass construction with a bright brass 605 finish and the original 00 keyway. The cylinder is UL437 listed for drill and pick resistance.

Mounting Hardware Included

A black mounting plate and two screws are supplied to secure the cylinder in place, simplifying installation on compatible rim lock bodies. The solid brass body provides durability and long cylinder life while the UL437 listing confirms tested resistance to drilling and picking. This hardware bundle means no separate mounting kit is required.

Door Prep and Keyway Check

Verify that your existing rim lock accepts a standard 1-1/16 inch rim cylinder and that the 00 keyway matches your current key system before ordering. The cylinder is held by the included plate and two screws, so ensure the door thickness and lock body allow proper engagement. Buyers needing a different keyway or a mortise cylinder format should look elsewhere.

Questions about this item

How often should the 00 keyway cylinder be rekeyed or replaced under normal use?

The solid brass 00 keyway cylinder is built for long life; rekey only if keys are lost or access needs change, otherwise no scheduled replacement is required.

What is the first performance limit reached during continuous forced-entry attempts?

The UL437 listing certifies drill and pick resistance, so the cylinder withstands sustained attack until the mounting screws or auxiliary rim lock hardware reach their structural limit.

Does the bright brass 605 finish or solid brass body generate noticeable heat or noise during all-day operation?

Mechanical rim cylinder operation produces no heat and only the faint click of the key turning; the brass body and finish remain at ambient temperature.
