For installation, create a bore in the door, cover or hatch as shown in the outline drawing.
Once assembled, the cam latch is inserted through the bore from the front. The hex nut can then be placed over the latch arm and onto the threaded housing and fastened in place.
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.
