FAQs
What is the TH 52 drilling pattern?
The TH 52 drilling pattern refers to the specific spacing and diameter of the holes drilled into the cabinet door to accommodate the hinge cup, measuring 52 mm center-to-center for the main holes and 5.5 mm for the locating pin.
Are screws and fixings included with the hinge?
No, screws and fixings for attaching the hinge to the door and the mounting plate to the cabinet are not included and must be purchased separately.
What is the maximum door thickness this hinge can support?
This hinge is suitable for door thicknesses ranging from 15 mm to 24 mm.
How do I adjust the door overlay?
The overlay can be adjusted using the integrated adjustment screw on the hinge, typically offering a range of +2 mm to -2 mm.
Can I use this hinge for full overlay doors?
No, this specific model (8645i) is designed for half-overlay applications. Hettich offers other Sensys models for full overlay configurations.
What is the benefit of the Silent System?
The Silent System provides a soft and quiet closing action for cabinet doors, preventing them from slamming shut and reducing noise.
How do I clean the nickel-plated finish?
Clean gently with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the finish.
Troubleshooting
Hinge does not close silently.
Ensure the Silent System mechanism is not obstructed. Check that the door thickness is within the recommended range (15-24 mm). Verify that the hinge is correctly clipped onto the mounting plate.
Door does not align correctly (overlay or depth issues).
Use the integrated adjustment screws on the hinge to correct the overlay (+2 mm / -2 mm) and depth (+3 mm / -2 mm). Ensure the mounting plate is securely attached and correctly positioned.
Hinge feels stiff or difficult to open.
Check for any foreign objects obstructing the hinge movement. Ensure the door drilling is correct and the hinge cup is seated properly. Light lubrication with a silicone-based spray might help, but avoid oil-based lubricants.
Hinge does not stay in position.
Confirm that all screws, both for the hinge cup and the mounting plate, are tightened securely. Check that the clip-on mechanism is fully engaged.
