GN 116.1

Rotary clamping latches

The outstanding feature of the rotary clamping latches GN 116.1 is their wide clamping range of 12 mm, with the 5 keys A1 to A5 covering a clamping range of 4 to 46 mm with broad overlap. This configuration allows large closing strokes within the individual key spacings, e.g. in connection with seals.

With the permissible tightening torque of 2 Nm for the clamping screw, the key generates a closing force of approx. 300 Nm at the key.

By turning the latch clockwise, the key is first turned by 90° and so moved into the closing position.

When continuing to turn, the thread (M10) will move it in axial direction (max. 12 mm) and will finally clamp the door against the frame.

When opening by turning anti-clockwise, the key will move back and will release the door by a 90° turn.

The pressure spring generates the friction required for the 90° turn.

When mounting, the door is fitted with a bore hole as shown in the outline drawing.

The interlock is pushed through the bore hole from the front, the hexagon nut can be pushed over the key from the back. The mounting step is only possible if the key is located axially in the end position and approximately in the middle of the range of rotation.
