Troubleshooting

Knob feels stiff or doesn't return properly.

Ensure the tubular latch is correctly installed and not binding. Check that the spindle is aligned properly and that there are no obstructions within the mechanism. Verify the door thickness is within the specified range (30-45mm).

Check and tighten the fixing screws located on the rose of the knob. Ensure the spindle is securely seated in both knobs.
