Solid Brass Mortise Cylinder

This MAXTECH B118KW1-03 cylinder replaces a worn mortise lock core in residential or light commercial doors. The solid brass body resists corrosion for indoor and outdoor installations. It arrives keyed different with a Kwikset KW1 keyway so each unit operates on its own key. The polished brass US3 finish matches common hardware trim.

Thread Size and Cam Compatibility

The cylinder uses a 1.150 x 32 UNS thread and a Standard Cam #1 to engage the existing mortise lock body. A 1.360 inch (34.5 mm) face diameter seats flush with standard escutcheons. The 1-1/8 inch length suits typical door thicknesses without protruding. No additional cams or adapters are required for most common mortise locks.

Suits Standard Mortise Retrofits

Homeowners and locksmiths replacing a single cylinder on a Kwikset-keyed system will find the dimensions and keyway match directly. Builders needing keyed-alike sets or a different keyway such as Schlage should select another model. Doors thicker than the 1-1/8 inch length require a longer cylinder not covered by this SKU.

Questions about this item

How long will the solid brass 1-1/8" mortise cylinder resist wear under daily entry traffic?

The cylinder body is machined from solid brass, a material that maintains dimensional stability and resists corrosion through years of repeated key insertion and turning.

Does the polished brass US3 finish or the 5-pin tumbler generate noticeable heat or noise during continuous operation?

Mechanical mortise cylinders have no moving parts that produce heat or audible noise; the brass finish remains at ambient temperature and the tumbler action is silent.

Which existing hardware must the door already have for the 1.150 x 32 UNS threads and 1.360" face diameter to engage correctly?

The door must be fitted with a mortise lock body cut for a 1-1/8" cylinder, standard #1 cam, and a 1.150 x 32 UNS threaded housing with a 1.360" (34.5 mm) face bore.
