GN 119 Latches Housing Zinc Die Casting, with Operating Element or Operation with Socket Key

By turning the latch clockwise (right) the stepped cam latch moves up behind the door frame and pulls the door in.

The large pulling-in range of the cam (10 mm) allows these locks to be used successfully on doors with sealing strips. When selecting clamping range A, any seal present must be taken into consideration.

For installation, make a hole in the door as shown in the outline drawing.
The lock housing with the preassembled operating bolt is fitted into the hole from the front and held in position with the mounting nut on the back side. The distance piece and cam latch are then pushed one after the other onto the operating bolt from the back side and fastened with the hex head screw.

The required installation hole in the door leaf, is usually generated by punching or laser machining in series production.

The installation hole diameter can also be created by drilling or milling as shown in the outline drawings.

For small series and steel sheets below 2 mm thickness, the Sheet Metal Punches GN 123 is alternatively the tool of choice.
