GN 119 Door Cam Latches Zinc Die-Cast, with Operating Elements or Operation with Socket Key

By turning the cam latch clockwise, the stepped latch arm moves up behind the door frame and pulls the door in.

The large draw-in range of 10 mm allows these latches to be used successfully on doors with sealing strips. When selecting clamping range A, the width of the door seal might have to be taken into consideration.

To fit the latch, the door will have to be provided with a hole as per sketch shown at a distance from the door frame to hole center of 23 mm.

The cam latch housing with the preassembled operating bolt is inserted into the hole from the front and held in position with the hexagon nut. The spacer and the cam latch arm are then installed from the backside and assembled together with the hex nut.

The installation bore in the door leaf is usually generated by punching or laser machining during a mass production run.

The installation bore can also be created by drilling / milling as shown in the outline drawings.

For small production runs and steel sheets below 2 mm thickness, Sheet Metal Punches GN 123 are the tool of choice.
