Secondary Lock Handle
SAF-Holland

This handle-driven secondary locking component provides the manual control required to engage or release the secondary latch in SAF-Holland systems. The design emphasizes precise actuation, with a small-diameter contact area (0.25 in) that preserves smooth, predictable operation while resisting wear over extensive service life. Classified under VMRS 059-001-043, the part is purpose-built for compatibility with the secondary locking family, and its inclusion in category 42784 situates it within locking hardware assemblies that govern secure coupling. Ergonomic considerations, such as reduced return torque and clear tactile feedback, translate into safer, faster maintenance cycles in the field. The handle assembly supports straightforward removal and replacement, helping technicians address wear or component fatigue without disassembling the entire lock. In service, it contributes to dependable lock actuation, reduces the risk of partial engagement, and supports consistent performance across a fleet. This component integrates with the broader locking system to maintain alignment, engagement force, and reliable operation in demanding trailer applications.
