General information

Features and applications

GN 215 levers can turn and block a spindle in a specific position. To turn the spindle, the arm is lifted, overcoming the resistance of a spring, until extracting the wedge-shaped pin from the notch (one-hand operation). Two stops can be used for the limitation of the manoeuvre angle, as shown in the drawing.

The arm with a wedge-shaped pin is the connection between the base and the spindle (standard execution). The pin is used to perform clearance-free locking, which also makes it easier to perform insertion and disconnection operations.

If clearance-free locking is not requested a cylindrical pin may be used (obtained from a M6x14 threaded screw). The notch is then made in a rectangular shape or replaced by a cylindrical hole. In this case the diameter of the hole must not hinder or prevent the pin from entering (rotation radius).

Manoeuvre angles

For standard notches, the smallest tolerable manoeuvre angles are:

  • D=54 manoeuvre angle = 11°
  • D=60 manoeuvre angle = 9°

Smaller angles may be obtained with a special execution of pin and notches.

Special executions on request

Notches (and even the stops for the limitation of the manoeuvre angle) may be machined in the position indicated in customer's drawing.
