Available in steel or stainless steel versions, Winco GN 810.4 vertical acting toggle clamps have two locking features in both the closed and open positions. During closing, a spring-loaded safety hook latch prevents inadvertent unlocking due to vibrations. The clamps are used for applications requiring any type of hold down, such as lids, flaps and quick-change components.
