These snap locks can be used to latch a door, cover or hatch but not to clamp it.
This is why it is important to position the locking distance A (door + frame width) with great accuracy and precision.
For snap locks GN 315, the locking distance can be set continuously via the setting sleeve adjustable via a precision thread. This makes installation a great deal easier.
For installation of the cam latch, create a bore in the door, cover or hatch as shown in the outline drawing.
The snap 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 or 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.
