Latches GN 115 lock by a turning operation limited to 90° which moves the locking behind the door frame. The bevels of the latch ease the closing of the door.

Latches with different cranks cover a latch distance A from 4 to 50 mm.

The operating bolt of the stainless steel version is fitted with an O-ring for sealing.

Latches GN 115 are supplied with loosely enclosed latch.

For installation, set a bore diameter in the door as shown in the outline drawing.

Once assembled, the latch is pushed through the bore diameter from the front. The hexagon nut can then be pushed over the latch from the back and bolted in place.

The installation bore diameter in the door leaf is usually generated by punching or laser machining in series production.

For small series and steel sheets below 2 mm thickness, the sheet metal punshes GN 123 are the tool of choice.

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