Sargent 13-0401 Cylinder Barrel – 41 Series Mortise Cylinder Rekeying
The Sargent 13-0401 Cylinder Barrel (also referred to as a cylinder plug) is a precision-machined internal component designed specifically for the Sargent 41 Series Mortise Cylinder. As the central rotating core of a mortise lock, the barrel is the primary interface between the user's key and the locking cam. Over years of high-frequency use in commercial and institutional settings, the internal pin chambers and the keyway of a cylinder can become worn, leadings to "key-turn" resistance or mechanical binding. This replacement hardware solution allows facility managers to restore factory-smooth operation to their existing Sargent mortise locks without the high cost of replacing the entire cylinder housing or the lock body.
As a critical locksmithing repair solution, the 13-0401 acts as a foundational security maintenance solution. Engineered to meet the exacting tolerances of the Sargent 41 Series, this barrel ensures that the shear line remains precise, which significantly reduces the risk of lock manipulation or picking. By choosing a genuine Sargent OEM barrel, you ensure that your high-traffic entrances—such as those in schools, hospitals, and government offices—remain secure and fully functional, extending the lifecycle of your Grade 1 architectural hardware.
Mechanical Utility & ANSI Security Summary
The cylinder barrel is the "heart" of the mortise system, providing the necessary rotational force to engage the deadbolt or latch bolt.
- Rotational Precision: The 13-0401 barrel is designed to rotate with minimal friction, providing the smooth-operation solution required for ADA compliance and user ease-of-access.
- ANSI/BHMA Grade 1 Standards: When integrated into a Sargent 41 Series cylinder, this component supports ANSI/BHMA A156.5 standards. This ensures the lock can withstand extreme cycles of use and physical force while maintaining perimeter integrity.
- Shear Line Integrity: Precision-drilled chambers ensure that the pins meet exactly at the shear line, providing a reliability solution that prevents "jiggling" or key-sticking issues common in aged hardware.
- Master Key System Compatibility: The barrel supports a variety of Sargent keyways (such as LA, LC, etc.), allowing for a seamless integration solution into complex, multi-level master key systems without compromising security hierarchy.

Engineered Solutions for Facility Access Control
The Sargent 13-0401 addresses the specific mechanical and logistical challenges of maintaining high-security commercial openings:
- Cost-Efficient Rekeying: When a key is lost or a security breach occurs, replacing only the barrel is a budget-friendly rekeying solution compared to purchasing a completely new cylinder assembly.
- Hardware Lifecycle Extension: Instead of replacing an entire mortise lockset when the cylinder becomes "sticky," replacing the internal barrel provides a sustainability solution that returns the hardware to "like-new" performance.
- Precision Timing Restoration: If the lock cam is not engaging properly, it is often due to wear in the barrel's tailpiece connector. Installing a new 13-0401 is the primary mechanical solution for restoring accurate latch retraction.
- Professional Aesthetic Maintenance: A worn or scratched cylinder face can diminish the professional appearance of a facility. Replacing the barrel provides a design-refresh solution, ensuring the face of the lock matches the surrounding architectural trim.
- Vandal-Resistant Security: Genuine Sargent barrels are manufactured to resist drilling and physical bypass techniques, acting as a perimeter security solution for sensitive areas like records rooms, pharmacies, and data centers.
