Cam latch E3 series

compressionkeyedstainless steel

Product overview
Southco’s VISE ACTION® E3 compression latches provide mechanical advantage to ensure tight, vibration-resistant door and panel closure for environmental sealing in demanding industrial applications. The VISE ACTION® mechanism aligns the cam behind the frame and, with a single continuous half-turn, draws the cam straight up to provide a consistent 6.4 mm (0.25 in) pull-up for gasketed sealing, reduce noise and prevent scraping. Over-center latching resists accidental opening from shock or vibration.
