Cylinder Cam Timing Alignment on Multi-Point Hookbolt Entrance Gearboxes
Engineering Overview: Installation guide on setting initial cam timing and angle indexing for Euro cylinders in multi-point shootbolt and hookbolt door gearboxes.
Technical & Engineering Specifications
| Cam Standard | DIN 30° Tucked Resting Position |
|---|---|
| Failure Mode | Turning key before lifting handle causes cam gear jamming |
| Hardware Type | Multi-Point Hookbolt / Shootbolt Door Gearboxes |
| Operation Sequence | Lift Handle (Throw Hooks) -> Turn Key (Deadlock Cam) |
Multi-Point Cam Engagement
In multi-point locks, the cylinder cam must drive heavy top and bottom locking hooks into door frame keeps.
Initial Setup Protocol
- Lift Handle First: Before turning the key, fully lift the door handle to throw all multi-point hooks into their keeps.
- Cam Deadlocking: Turning the key 360° drives the cylinder cam into the primary deadbolt follower, deadlocking the handle mechanism.
- Cam Timing: Ensure the DIN 30° cam rests safely inside the teardrop profile to avoid latch binding.
