Southco Vise Action compression latches with gaskets. Designed for quick, secure closure in applications where vibration, sealing, and quality are paramount. 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 0.25-inches 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. Easy-to-grip knob and handle-actuated styles provide quick, simple access. These styles restrict access and discourage vandalism. Gasketed models satisfy NEMA 4 and IP-65 applications. Available for EMI/RFI sealing. Industry applications includes rail, aerospace, bus and coach, specialty vehicle. Handle/knob profile. Latch assembled: no. 0.71-inches door thickness.
