Installing SKG-certified frame parts for auxiliary boxes

  1. Insert the frame parts into the milled door frame.
  2. Fix the frame parts in the frame with the prescribed screws.
  3. Install the door, ensuring that the interval between the hook bolt and frame part is no greater than 1 mm.
    This ensures that the hook bolt moves fully into the locking position and achieves the specified minimum dimension for engagement in the frame part.
  4. Check that the hook bolt moves completely into the locking position and release position with ease.
