Rotary clamping latches, Zinc die casting

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.
