Solid Brass Dummy Cylinder

The Kaba Group 7200DC-03 is a solid brass dummy mortise cylinder finished in polished brass US3. It provides a thumb-turn actuator without a keyway for interior or exterior doors that need a fixed turn piece. The 1-1/4 inch length suits standard door thicknesses.

Thread and Cam Compatibility

This cylinder replaces an existing mortise unit that uses a 1.150 x 32 UNS thread and an Adams Rite Cam #2. The upgrade is worth it when the old cylinder face measures 1.360 inches or 34.5 mm and the lock body accepts the same thread pitch.

Mortise Lock Fit Limits

The dummy function means no key operation is possible from either side. It will not work where a keyed cylinder or a double-cylinder keyway is required. The fixed 1-1/4 inch length and specific cam restrict use to mortise locks matching those exact dimensions.

Questions about this item

What thread size and cylinder face diameter does the 7200DC-03 need to fit my mortise lock?

The cylinder uses a 1.150 x 32 UNS thread and a 1.360 (34.5mm) face diameter, matching standard mortise lock preparations.

How is the Adams Rite Cam #2 oriented during installation, and what step is often missed?

Insert the cylinder so the cam engages the lock body, then tighten the set screw; the missed step is verifying the cam rotates freely before final tightening.

Will the solid brass finish or the thumb-turn mechanism need periodic maintenance?

The US3 polished brass may darken over time and can be restored with brass polish; the thumb turn has no keyway to lubricate.
