Thetford parts reference
Thetford 627571
Latch Plate-Door/Black
627571 is the Thetford part number for the latch plate-door/black. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.
Thetford says to use 638579 instead
Thetford marks this number with “USE 638579” on its own parts list, which is the manufacturer telling you 638579 is what to order now. That instruction comes from the document, not from us, and not from what sellers happen to call the part.
Current number: 638579
Which parts lists carry this number
It appears on the parts lists for 4 different models: N180 Series, N300 / N400, N305 Series and N51 SeriesN41 Series. A number shared across several models usually means the component was carried over between them, which is useful when the exact list for your model is not the one you can find.
Check the version before you order
This part comes in more than one version, and they differ by colour. Ordering the wrong one gets you a part that is real, correct for the model, and still not the one you need. The other versions on the same documentation are listed below — check yours before ordering.

What we have not checked
We can show you that 627571 is a real Thetford number, what Thetford calls it, and which parts lists carry it. We have not verified that it fits your camper. That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
