Thetford parts reference
Thetford 640435
Kit Service Hinge Support
640435 is the Thetford part number for the kit service hinge support. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.
Which parts lists carry this number
It appears on the parts lists for 2 different models: N7 & N8 Polar Series and N7/N8 POLAR 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.
Availability
Thetford marks this number with an asterisk, and the legend on that document reads “LIMITED AVAILABILITY”. It is still a live number, but supply is constrained, so it is worth checking secondary sources rather than assuming it is freely stocked.

What we have not checked
We can show you that 640435 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 That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
