- Disassemble Interior Knob (if necessary): Before installing the interior knob, you may need to disassemble the rear lock ball. Get the interior knob and rotate it. Align the internal protruding part and use the knob release tool to depress the knob retainer and pull the knob out of the spindle.
- Connect Knobs: Match the exterior knob to the keyhole and pass it through the lock latch. Then, connect the interior knob and exterior knob together. Ensure the alignment points are matched for proper assembly.
- Secure the Knobs: Connect the rear lock and front lock together. Use a screwdriver to tighten the screws that hold the interior and exterior knobs together through the door.
- Final Assembly: Finally, buckle the rear ball lock against the rear lock body. Be sure to buckle and install according to the corresponding position.
Operation
The ARPHA H200 dummy door knob is designed for simple push/pull operation. The knob can be turned on both sides, but it does not engage a latch or lock mechanism. It is ideal for doors that only require a pull to open and push to close, such as closet doors or pantry doors.
