The smooth operation of the VISE ACTION® design aligns the pawl behind the frame and draws it up tight 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.
