the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Repair an accepted accessible rail or fit a compatible running insert or replacement section without changing the building envelope.
Signs: the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally or the door sags, rubs, sticks or has uneven gaps around the opening. Causes: normal wear in hinges, latches or compatible mechanical hardware or loose fixings, minor alignment drift or ordinary timber movement.
A replacement rail or insert needs the correct shape and dimensions. Provide the system reference where available. Similar-looking tracks may support different rollers, so a generic strip should not be assumed to be a suitable repair for every sliding door.
Show the points where movement catches as well as the full track. Local damage may have a different repair option from extensive wear. Photographs help describe the problem but cannot establish that the track, rather than the rollers or frame, is the only cause.
Repair an accepted accessible rail or fit a compatible running insert or replacement section without changing the building envelope. Limits: Accessible non-structural running rails only. No threshold waterproofing alterations, drainage-system redesign, structural changes, major glazing or powered operators.
