Vertical Acting Toggle Clamps GN 812

Type: EV - Solid bar version, with weldable clasp

Operating Principle Toggle Lever / Overview of Toggle Clamp Types Plastic Characteristics

Product description

Vertical acting toggle clamps GN 812 work according to the toggle principle. Lever and clamping bar move in the opposite direction. They require less space for the clamping action because the operating lever is located to the side below the clamp while in the clamped position. The two mounting surfaces oriented at 90° to each other allow for space-saving installation next to the clamping point.

Vertical acting toggle clamps with forked clamping arm of type AV can accommodate an application-specific screw via the flanged washers. A spindle assembly with rubber thrust pad is also included with type CV.

Vertical acting toggle clamps of type EV can be adapted to special requirements by welding on the supplied clasp.
