JW Winco, Inc.  now offers GN 927 Clamping Levers with Eccentrical Cam, in Tapped Type and Threaded Stud versions.

The RoHS compliant GN 927 clamping levers with eccentrical cam are used for rapid clamping and releasing operations. In contrast to a clamping operation utilizing threads, these levers permit torque-free clamping. The lever has been designed to insure its movement cannot exceed the maximum clamping position. In addition, there are no loose components, since all are assembled and mounted in their correct order. With these clamping levers, thrust forces of up to 1.8 pounds (8 N) can be obtained.

The lever is zinc die cast, plastic coated, with an abrasion-proof epoxy resin finish, while the components are steel, zinc plated with a blue passivated finish. The Clamping Levers are available in black, orange, red, or silver.

A version with an adjustable bearing plate allows for the distance between the eccentrical cam and the contact surface to be adjustable by means of a fine threaded knurled nut. This permits the maximum clamping force to be set by a simple adjustment. In addition, this also permits the selection of a preferred lever position in relation to the clamping lever pin.

For the version with the adjustable bearing plate with setting nut, the plate is black technopolymer (Polyamide), glass fiber reinforced, while the setting nut is steel, zinc plated in a blue passivated finish. The Bearing Plate on the version that is fixed is technopolymer (Polyamide), glass fiber reinforced.
