A sound leaf that only rubs or latches poorly may suit adjustment or hardware repair instead. Replacement is considered for an unsuitable or damaged leaf after checking that the existing opening can accept the proposed door.
the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Hang the compatible replacement leaf, fit agreed ordinary hardware and check floor clearance, alignment and closing in the unchanged opening.
Signs: the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally or the door closes poorly despite an otherwise sound visible opening. Causes: local damage to an accessible component rather than an assumed structural defect or normal wear in hinges, latches or compatible mechanical hardware.
Factory cut-outs can restrict which handle or latch will fit. Show the hardware from both sides and the latch edge. Ordinary compatible hardware transfer can be considered, but existing holes should not be assumed to match a different product simply because both are internal doors.
Check the swing across the actual floor, including rugs and any planned flooring change. The aim is a workable clearance with an aligned leaf. Removing excessive material to compensate for an unsuitable opening is not a substitute for checking compatibility first.
