A turning motion limited to 90°, e.g. of the triangle in type DK, locates the locking behind the frame to close the door. The latch arms of diffe- rent lengths, some of which are crimped, can be mounted for foldover, opening up a wide range of applications. The details on load-bearing capacity F 1 and F 2 were determined with a wall thickness s = 1,5 mm. Latches with gripping tray GN 731.2 / GN 731.5 are supplied with loosely enclosed latch arm. Two socket keys made of plastic or two brass keys are included parts of the order.
