Southco Barrel Lock Cylinder for AEV HVAC door

The Southco E3-55-55 is a high-performance VISE ACTION® compression latch designed for demanding applications, including AEV HVAC doors and emergency vehicle compartments. This small-sized, key-locking latch features a robust zinc alloy construction with a durable black powder coat finish, ensuring resistance to environmental factors and vibration.

Engineered for reliability, the VISE ACTION® mechanism aligns the cam behind the frame and pulls it tight with a single, continuous half-turn motion. This provides consistent compression, effectively sealing out water and dust while eliminating noise and rattles common in mobile or heavy-duty industrial environments.
