Trim or sand the areas of contact if needed. Test the door’s operation by opening and closing it a couple of times. Make further adjustments if it isn’t running smoothly.

Be mindful of the following:

  • All sides of the door should have consistent spacing when adjusting.
  • Reinstall any weatherstripping or insulation after the adjustments.

  2. Mark the spot on both sides of the door where the handle should go. Make sure it’s comfortable and convenient.
  3. Drilling template or hole saw? Choose one to create a hole in the door at the marked spot. Be sure to stay steady and align it properly.
  4. Insert the latch into one side of the door. Ensure it’s secure and functioning. Use screws for extra safety.
  5. For the exterior handle, use its accompanying screws for extra hold. Balance practicality and aesthetics.
  6. Fit in the interior handle through its designated hole. Secure it tightly with screws.
