Information
Hook-type latches GN 115.8 with hook and latch bracket are mainly used for sliding doors and flaps. The locking action is in radial direciton to the axis of rotation, resulting in a wide variety of different uses.
The types with a different lock are available in more than 200 variants, whose key is marked by numbers.
The scope of delivery includes a separately enclosed hook as well as two keys removable in both end positions.
Construction and Assembly Instructions
The bolt diameter may be shifted by 10 mm, making it easier to adapt the locking mechanism to the installation site.
When locked, the bolt is ideally positioned at the level of the axis of rotation 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°.
For installation, set a bore diameter in the door as shown in the outline drawing.
Before mounting the hook, the locking mechanism must first be mounted in the door leaf (using the enclosed hexagonal nut).
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.
