Sargent 13-3142 Cylinder Barrel Plug – US15 Finish | 6, 7, 10, 11 Line Compatibility
The Sargent 13-3142 cylinder barrel plug is a genuine Sargent replacement component designed for use across the Sargent 6 Series, 7 Line, 10 Line, 10X Line, 11 Line, and 6500 Series bored locksets. Finished in US15 (Satin Nickel), this barrel plug delivers a precise, factory-fit solution for facilities maintaining or restoring existing Sargent lock hardware without full cylinder replacement.
This cylinder barrel is available in both standard and restricted keyway configurations (keyway suffix varies by SKU). The restricted keyway option provides key control — limiting unauthorized key duplication — making it well suited for schools, healthcare facilities, government buildings, and commercial properties where key management is a priority.
Key Benefits
- Broad series compatibility: Fits Sargent 6, 7, 10, 10X, 11 Line, and 6500 Series bored locksets — a single component that spans a wide installed base
- Restricted keyway availability: Supports key control programs by limiting unauthorized duplication on applicable SKUs
- US15 finish (Satin Nickel): Coordinates with common commercial and institutional hardware finishes for a consistent, professional appearance
- Genuine Sargent component: Ensures proper fit, function, and finish match within existing Sargent lock systems
- Service-level repair: Allows barrel/plug-level service rather than full cylinder or lockset replacement, reducing downtime and cost

- Replacement or re-keying service on Sargent 6, 7, 10, 11 Line cylindrical locksets
- Facilities management — maintaining large installed bases of Sargent bored hardware
- Institutional and commercial buildings requiring key control with restricted keyways
- Schools, healthcare, and government properties undergoing hardware refresh or rekeying programs

The Sargent 13-3142 Cylinder Barrel is a precision-engineered internal component designed specifically for the Sargent C10-1 cylinder assembly. This barrel acts as the rotating core of the lock, housing the pins and springs that interface with the key. Finished in a sophisticated US15 (Satin Nickel), this replacement hardware solution is essential for restoring the mechanical integrity of high-traffic commercial lever sets. Whether you are dealing with a "sticky" lock or a barrel that has suffered from internal wear, the 13-3142 provides an immediate maintenance solution that restores the smooth, tactile feedback expected from premium Sargent hardware.
As a critical locksmithing component, this barrel is compatible with a wide array of Sargent’s most robust lock series, including the 10 Line and 11 Line heavy-duty cylindrical locks.

By choosing a genuine Sargent OEM barrel, you ensure that the shear line remains precise, which acts as a security enhancement solution by reducing the risk of bypass through picking or forced manipulation.

Mechanical Function & ANSI Security Summary
The cylinder barrel is the heart of the locking mechanism, serving as the primary interface between the user's key and the lock's retraction components.
- Rotational Precision: The barrel must align perfectly with the plug and housing to allow for the ANSI/BHMA Grade 1 requirement of smooth operation under high-cycle counts.
- Shear Line Integrity: The precision-drilled pin chambers in the 13-3142 ensure that the driver and bottom pins meet exactly at the shear line, providing a reliability solution that prevents "jamming."
- Torsion Resistance: Built to withstand the torque applied by heavy commercial keys, this barrel serves as a durability solution for doors that experience hundreds of cycles per day.
- Finish Durability: The US15 Satin Nickel finish on the face of the barrel is designed to resist the corrosive effects of hand oils and cleaning chemicals, ensuring the lock maintains a professional aesthetic.
Engineered Solutions for Facility Security
The Sargent 13-3142 addresses specific operational hurdles faced by facility managers:
- Cost-Effective Lock Restoration: Instead of replacing an entire Sargent 10 Line Lever Set, which can cost hundreds of dollars, replacing a worn barrel is a budget-friendly solution that returns the lock to factory-new performance.
- Master Key System Maintenance: When a keyway is worn or damaged, it can compromise the security of an entire wing. This barrel is the primary rekeying solution, allowing locksmiths to drop a new core into an existing lever set.
- Aesthetic Matching: The Satin Nickel US15 finish provides a design-consistent solution for modern office interiors, blending perfectly with existing stainless steel or chrome hardware.
