Thetford Service Door Lock Mechanism Repair Kit (Doors 3, 4 & 5)

This is Thetford's repair kit for the lock mechanism inside caravan and motorhome service access doors 3, 4 and 5, the small hatches typically used for water tank fills, waste cassette access or storage lockers. The kit supplies the internal catch and lock components as a set, so if the door will not latch properly, feels loose, or the lock has broken internally, this restores it without replacing the whole door.
