GN 115.8-L-ZD-SCK Hook-Type Latches With wing knob (same lock)

Hook-type latches GN 115.8-L-ZD with hook and latch bracket are mainly used for sliding doors and flaps. The locking action is in radial direction to the axis of rotation, resulting in a wide variety of different uses.

The latches are delivered with 2 keys and loosely enclosed hook. The key can be removed in both end positions.

Types with a standard lock allow every lock to be opened with the same key. For the types with different lock, there are more than 200 different lock variants, whose keys are marked by numbers.

For installation, set a hole in the door, cover or hatch as shown in the outline drawing.

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

The installation bore 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 punch GN 123 are the tool of choice.

The hook can only be attached to the latch after installing the lock housing in the door leaf.

The bolt of the latch bracket can be shifted vertically within a slot by ± 5 mm, making it easier to adjust the latch during installation.

Ideally, the bolt should be in the plane of the rotational axis when locked, as shown. A sideways offset of as much as 4 mm does not impair the proper function.

The angle of rotation of the hook is normally limited to 90°.

Depending on the mounting of the contact pin supplied loose, the locking action is effected by turning left or right.

Without the contact pin, the hook can be rotated by 360°.
