Properties and application:

  • GN 820.3 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 ML) can accommodate an application specific clamping screw
  • A spindle assembly with neoprene rubber tip is also included for Type MLC
  • To Type OL 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 ML: U-bar version, with two flanged washers
  • Type MLC: U-bar version, with two flanged washers and GN 708.1 Spindle Assembly
  • Type OL: Solid bar version, with clasp
  • Elesa+Ganter toggle clamps - operating principle
