Solid Brass Mortise Cylinder

The Kaba Group 7185FA1-03 is a 1-1/8 inch solid brass mortise cylinder finished in US3 polished brass. It uses a Segal SE1 keyway and a standard #1 cam, supplied keyed different for individual access control. The 1.150 x 32 UNS thread and 1.360 inch face diameter match common mortise lock preparations. Suitable for residential or commercial doors where a durable brass cylinder is required.

Brass Construction and Pin Tumbler Operation

Solid brass bar stock resists corrosion during long-term indoor or outdoor exposure. The 5 pin tumbler mechanism maintains consistent engagement through repeated locking cycles without the wear seen in softer alloys. Polished brass finish retains appearance under daily handling and environmental changes. Standard cam design transfers torque reliably to the lock body over extended service periods.

Thread and Dimensional Compatibility Limits

The 1.150 x 32 UNS thread pattern fits mortise housings cut to that specification; doors with different thread pitches will not accept this cylinder. Face diameter of 1.360 inches (34.5mm) requires a matching bore in the lock body. Length of 1-1/8 inch suits doors of corresponding thickness; thicker or thinner doors need a different cylinder length. Segal SE1 keyway restricts key duplication to blanks cut for that profile.

Questions about this item

How much heat or noise does the 7185 cylinder generate when the door is locked all day?

The solid brass cylinder has no moving parts while locked, so it produces no heat and no noise during continuous use.

What existing hardware must the door already have for this 1.150 x 32 UNS thread cylinder to install?

The door needs a mortise lock body cut for a 1-1/8" cylinder with a 1.360 inch (34.5 mm) face diameter and standard cam #1 engagement.

Will the Segal SE1 keyway work with the older keys I already carry?

Only keys cut to the Segal SE1 profile will operate this cylinder; keys from other keyways will not fit or turn.
