Solid brass dummy mortise cylinder

The MAXTECH B118DC-03 is a solid brass dummy mortise cylinder finished in US3 polished brass. It measures 1-1/8 inches in length with a 1.360 inch diameter face. The cylinder uses an Adams Rite Cam #2 and a 1.150 x 32 UNS thread. A thumb turn operates the mechanism without a key.

Replaces worn or mismatched dummy cylinders

This cylinder fits mortise locks that accept the 1.150 x 32 UNS thread and 1.360 inch face diameter. The jump is worth it when the existing cylinder has stripped threads, a damaged cam or a finish that no longer matches the door hardware. Solid brass construction resists corrosion better than plated zinc alternatives.

Fits standard mortise lock bodies

Installation requires a mortise lock body with matching thread and face dimensions. The thumb turn design frees the keyway for single-sided operation on interior doors or paired with a keyed cylinder on the exterior. Buyers who need a keyed cylinder or a different cam style should select a compatible model instead.

Questions about this item

Will the 1.150 x 32 UNS thread and 1.360 diameter face fit my existing mortise lock?

Yes, the cylinder uses a 1.150 x 32 UNS thread and a 1.360 (34.5mm) face diameter, matching the most common mortise lock prep.

How do I install the Adams Rite Cam #2 so it engages the latch?

Thread the cylinder into the mortise body until the cam aligns with the latch bolt; secure with the set screw through the lock body.

Does the solid brass cylinder or thumb-turn mechanism need any lubrication over time?

The solid brass body is corrosion-resistant; apply a light PTFE lubricant to the thumb-turn spindle annually for smooth operation.
