benedict, the 124 doors are adjustable. Be sure to make some match marks at each hinge so you have several reference points before loosening the hinge bolts. Best to swing the door wide open and support the door from underneath with some wood blocking before loosening any bolts so the door doesn't drop. Use the reference points to make slight, incremental adjustments, snugging up the bolts after each adjustment, until the door fits properly. Once you're satisfied with the fit tighten the hinge bolts to 18ft/lbs (25Nm).
