For operators of off-highway and agricultural equipment, cab entry doors can be a daily frustration. Rough environments cause vibration, accidental door releases risk safety, and complex access mechanisms can slow down work in the field. Heavy-duty equipment demands a latch system that is just as rugged, reliable, and easy to use as the machinery it protects.
Southco has introduced a new solution designed to tackle these challenges head-on: the R4-50 Rotary Latch with Dual Triggers Engineered for demanding conditions, the R4-50 delivers:

• Independent interior and exterior actuation – making it easier and safer to enter and exit equipment cabs.
• A pre-loaded interior hand lever – purpose-built for high-impact environments, reducing noise and vibration while ensuring smoother, more reliable operation.
• Accidental actuation prevention – minimizing unintended movement to keep operators secure and equipment protected.
• Flexible release options – including remote actuator connection via cable or rod, or direct push release, to meet different cab design needs

Southco’s R4 Rotary Latch series is highly durable, and is available in a variety of configurations that meet customer needs with little to no modification, including compact mechanical and electromechanical designs made of durable materials suitable for any environment. R4-50 Rotary Latches with Dual Triggers are capable of meeting FMVSS 206 impact standards, and EN 45545-3 fire protection standards

As a heavy-duty upgrade to Southco’s trusted R4 Rotary Latch line, the R4-50 with Dual Triggers combines operator safety, rugged durability, and simplified access in one cost-effective system. The latch is also compatible with Southco AC actuators, offering OEMs a low-investment, high-value option for enhancing their cab entry solutions.

Global Product Manager Cynthia Bart adds, “The new R4-50 Rotary Latch with Dual Triggers offers a complete, highly versatile cab door entry system for use in heavy-duty construction and agricultural vehicles. The latches are compatible with Southco AC Actuators, allowing designers to quickly and affordably upgrade their existing designs.”
