Solid brass dummy mortise cylinder

The Kaba Group 7180DC-26D is a solid brass dummy mortise cylinder finished in US26D satin chrome. It measures 1-1/8" in length with a 1.360 inch (34.5mm) diameter face and uses a 1.150 x 32 UNS thread. The unit features an Adams Rite Cam #2 and operates via a thumb turn with no keyway. It suits interior or exterior doors needing a non-locking mortise fit.

Sustained use and finish durability

Solid brass construction resists corrosion during long-term indoor or outdoor exposure. The satin chrome finish maintains appearance under frequent handling without plating wear common on coated zinc alternatives. Threads remain true across repeated installation or removal cycles. The thumb-turn mechanism contains no springs or tumblers to fatigue over time.

Installation fit and common issues

Installation requires a mortise pocket matching the 1.150 x 32 UNS thread and 1.360 inch face diameter. The Adams Rite Cam #2 must align with the existing lock body to operate the latch. Mis-threaded starts damage the brass threads; hand-thread carefully before final tightening. Buyers needing a keyed cylinder or a different cam profile cannot use this dummy model.

Questions about this item

Does the solid brass 1-1/8" cylinder generate any heat or noise during continuous daily use?

No, the dummy mortise cylinder has no moving mechanism or electronics, so it produces no heat and makes no sound during operation.

What existing door hardware is required for the 1.150 x 32 UNS thread and Adams Rite Cam #2 to engage properly?

A mortise lock body with matching 1.150 x 32 UNS threading and an Adams Rite Cam #2 slot is needed for the cylinder to install and function.

Will the 1.360 inch cylinder face and thumb-turn operation work with an older mortise lockset that uses a different cam style?

The cylinder requires an Adams Rite Cam #2 interface; locks with other cam types will not accept this cylinder without modification.
