Southco’s VISE ACTION® Compression latches provide mechanical advantage, ensuring tight, robust vibration resistant door closure to seal out water and dust in the most strenuous applications. The smooth operation of the VISE ACTION® design aligns the cam behind the frame, then draws it straight up tight to prevent scraping against the frame, with a single continuous half-turn motion.  Its compression action provides consistent 6.4 mm (.25”) pull-up for environmental sealing in gasketed applications, and helps reduce or eliminate noise and rattles caused by vibration.  Over-center latching resists accidental opening due to shock or vibration.
