The most likely reason is an incorrectly adjusted door leaf. See “Adjusting the door leaf” section in the Skaala operating, installation and maintenance manual, pages 8–9.
First check that you are opening the door correctly: the handle must be fully open (90⁰). If the problem persists, see the “Operation of external and balcony doors” section in the Skaala operating, installation and maintenance manual, page 9.
Check whether the latch bolt is correctly aligned with the counterpiece. If it is not, check the door adjustments; see the Skaala operating, installation and maintenance manual, page 8. If you are unable to fix the fault, contact a locksmith.
The frame depth is the width between the inner and outer edges of the door or window frame. The suitable depth depends on e.g. the thickness of the wall. We recommend checking the appropriate frame depth with a Skaala expert.
The dimensions always include the frame. Our quotes specify the exact dimensions of each standard-size door, but otherwise the dimensions are usually rounded up or down to the nearest 10cm. Example: If the exact dimensions are 890 x 2,090, the size is indicated as 9×21 Note: This does not apply to custom-made doors.
