Southco's E3 Vise Action Compression Latches Require Minimal Force for Maximum Seal

Southco’s E3 VISE ACTION® compression latch series administers quick, secure closure in a single motion and is ideal for applications where sealing, quality, and vibration are crucial. The VISE ACTION® technology provides a mechanical advantage, supporting easy access through a key or tool while simultaneously ensuring a snug, vibration-resistant closure. In a single half-turn motion, the cam and shaft compress and pull the door tightly against the frame into the locked position, sealing out dust and water. In gasketed applications, the compression action provides consistent 6.4 mm (.25”) pull-up for environmental sealing and reduces noise and rattling caused by vibration. Additionally, the over-center latching placement prevents accidental opening causes by shock or vibration.

Multiple size, material, and access configuration options suit various applications and industry requirements, allowing the latch to meet the needs of unique applications. A large selection of head styles, such as t-handle and key or tool operated styles, provide solutions for varying security requirements. At the same time, multiple grip dimension options help create the perfect fit. Three basic housing styles are also available to meet door configuration and mounting requirements. The series’ high-durable materials and finishes excellently resist corrosion and match diverse style and functionality requirements. Furthermore, the latch solutions support a wide range of load configurations.

Through its VISE ACTION® design, the E3 Compression Latch achieves tight, water, dust and vibration resistant compression with minimal manual torque. The series delivers quality, security, and consistency through a user-friendly model and offers various product configurations to meet the unique needs and challenges of each application.
