ANSl Solid Brass Cylinder

The ANSl Solid Brass Cylinder is a high-precision IC core cylinder developed for secure and flexible access control systems. Featuring a 6 pin interchangeable core structure, this cylinder supports efficient key management and quick core replacement, making it suitable for projects requiring scalable security solutions. Manufactured from solid brass with an SSS-covered head, it delivers stable mechanical performance and long-term durability across various door environments. Available in two standard sizes, this cylinder complies with ANSl mortise cylinder specifications and fits a wide range of door types including wooden doors, metal doors, interior doors, and exterior swing doors. This product is well-suited for OEM and ODM projects where consistency, finish customization, and reliable performance are critical for bulk order supply.

1. ANSI Mortise Interface

DDLC013-A and DDLC013-B follow the ANSI mortise cylinder standard for use with compatible mortise locks, exit devices, and architectural door hardware. Their standardized form helps door manufacturers verify threaded connections and cylinder positioning before preparation. The Solid Brass Cylinder supports wooden, metal, interior, exterior, and swing doors, reducing hardware coordination work across mixed-door projects.

2. Interchangeable Core Housing

The product is available with a small-format interchangeable core housing for the BEST format and a large-format housing for the Schlage C format, including a 26D finish choice. Authorized staff can remove and replace the compatible core without disassembling the complete lock. This arrangement shortens rekeying and maintenance work in facilities requiring frequent access changes.

3. 28.5mm and 31.8mm Lengths

DDLC013-A measures 1-1/8 inches or 28.5mm, while DDLC013-B measures 1-1/4 inches or 31.8mm. Buyers can select the Solid Brass Cylinder according to lock depth, door construction, and trim thickness, keeping the cylinder head at an appropriate projection. Separate dimensional references also reduce length-mixing errors during volume ordering and installation.

4. Six-Pin Keying

The Solid Brass Cylinder supports a six-pin locking configuration for mechanical keying in commercial and residential doors. Its interchangeable-core arrangement enables property teams to update cores and rekey doors by room, department, or access level. This is particularly helpful for exit devices and other applications where complete lock removal requires additional labor, tools, or interruption.

5. Brass Body and Finishes

A solid brass body provides a precisely machined base, while the cylinder head carries an SSS cover for visual coordination with exposed hardware. Available treatments include plated, PVD, matte black, satin nickel, antique brass, antique copper, polished brass, and chrome. DDLC013 can therefore match selected levers, lock trims, and door finishes across hotel, office, and commercial projects.

1. Office Buildings

Private offices, record rooms, and controlled areas frequently require changes to key authorization. The Solid Brass Cylinder uses an interchangeable core that authorized personnel can replace without removing the complete mortise lock. Small-format BEST and large-format Schlage C housings can be selected to align with an existing keying plan and support department-based access management.

2. Hotel Service Rooms

Linen rooms, storage rooms, equipment spaces, and staff offices may need key access reassigned as operating roles change. DDLC013 enables fast core replacement while limiting disruption to the door. Lengths of 28.5mm and 31.8mm accommodate different lock and trim assemblies, while the Solid Brass Cylinder can be finished to match each hotel service zone.

3. Shopping Mall Glass Doors

Some all-glass door locks used in retail stores and showrooms require extra labor to disassemble. When access permissions change, an interchangeable core helps reduce servicing work. The Solid Brass Cylinder offers small- and large-format IC core housings for compatible core formats. Six-pin capability and multiple finishes also support varied storefront lock and design requirements.

4. Public Building Exits

Exit devices in schools, hospitals, and public facilities are not practical to dismantle for every keying change. DDLC013 allows facility teams to replace the interchangeable core and rekey the opening without taking apart the complete exit hardware. The Solid Brass Cylinder supports wooden or metal swing doors and is available in finishes including 26D.
