Thetford Spares Kit for Service Door 3, 4 & 5
Contains common replacement parts for hinge, spring & more
This Thetford spares kit lets you repair the access door used to remove the cassette on Thetford toilets, as used in campervans, caravans, motorhomes and boats. Please note that there are no instructions with this spares kit, so care will be needed when disassembling to ensure you remember the position of components e.g. springs. 

This parts kit includes many components of the locking/latching mechanism used in the service door - but it does not include the lock barrel itself, which is available separately here.
Many of the parts included in this kit are only available as a part of this kit.
