Solid brass mortise cylinder

The MAXTECH B114KW1-03 is a 1-1/4 inch mortise cylinder built from solid brass with a US3 polished brass finish. It uses a Kwikset KW1 keyway and a standard number one cam, and it ships keyed different for immediate installation.

Threaded brass body holds alignment

A 1.150 x 32 UNS thread and a 1.360 inch (34.5 mm) cylinder face diameter keep the cylinder seated firmly in the mortise pocket. The five pin tumbler mechanism operates smoothly through repeated locking cycles without binding or finish wear.

Replaces worn or mismatched cylinders

This unit fits most mortise locks that accept the listed thread and face dimensions, upgrading from damaged brass or incompatible keyways. It is not suited for locks requiring a different thread pitch, a larger face diameter, or a non-Kwikset keyway.

Questions about this item

Does the 1-1/4" solid brass cylinder generate heat or noise during continuous daily use?

No. The mechanical 5-pin tumbler cylinder has no motor or electronics, so it produces no heat and operates silently.

What existing door hardware is required for the 1.150 x 32 UNS thread and Standard Cam #1 to engage?

A mortise lock body with matching 1.150 x 32 UNS threading and a standard cam slot, plus a 1-3/8" bore for the 1.360" cylinder face.

Will the Kwikset KW1 keyway accept the same keys as my older Kwikset deadbolts?

Yes. The KW1 keyway matches standard Kwikset residential key blanks, so existing Kwikset keys can be cut to operate this cylinder.
