Product identity

The Marks USA 2122-26D-C is a solid brass mortise cylinder lock with a satin chrome US26D finish, measuring 15/16 inch in length. It is intended for property owners and maintenance staff replacing cylinders on interior or exterior mortise locksets.

Included accessories

Two keys are supplied with the 5 pin tumbler cylinder, allowing immediate use after installation. The standard cam is fitted and the unit can be re-keyed or adapted to different cams, so the same hardware works across multiple doors without extra parts.

Build and mounting

Solid brass construction resists corrosion in indoor and outdoor environments, while the satin chrome coating maintains appearance through daily handling. The 15/16 inch body fits most mortise locks on the market, and the keyed-different configuration ensures each cylinder operates independently.

Questions about this item

Will the 5 pin tumbler cylinder need re-keying or replacement over time?

The solid brass cylinder can be re-keyed by a locksmith when keys are lost or access changes; no scheduled replacement is required for the cylinder itself.

What is the first limitation that appears under sustained daily use?

The 15/16" length and standard cam determine fit; if the mortise pocket or door thickness differs, the cylinder will not engage properly.

Does the satin chrome finish or brass body generate noticeable heat or noise during constant operation?

Mechanical mortise cylinders have no powered components, so they produce no heat and only the quiet click of the 5 pin tumbler when turned.
