Properties and application:
- GN 820.4 horizontal acting toggle clamps have a safety function whereby, during closing, a spring loaded safety hook latch ensures a secure locking connection
- It prevents the inadvertent unlocking of the clamp due to vibrations or an accidental attempt of loosening / opening of the clamp
- To open and release the clamp, pull up on the finger grip to disengage the safety hook latch mechanism (one hand operation)
- They work according to the toggle principle: lever and clamping bar move in the opposite direction
- They require less space for the clamping action
- Horizontal acting toggle clamps in the U-bar version with two flanged washers (Type NL) can accommodate an application specific clamping screw
- A spindle assembly with neoprene rubber tip is also included for Type NLC
- Type PL version can either be utilized by welding the clasp which can then accommodate an application specific hold-down fastener component, or by utilizing the bar in conjunction with the GN 809 Clamp Mounts to hold the work piece in place
- Type NL: U-bar version, with two flanged washers
- Type NLC: U-bar version, with two flanged washers and GN 708.1 Spindle Assmebly
- Type PL: Solid bar version, with clasp
- Elesa+Ganter toggle clamps - operating principle
