Frequently Asked Questions

Q: Do I need new bolts every time I remove the toilet?
Not always, but it’s recommended if bolts are rusted, stripped, or difficult to tighten.

Q: Will this fit other Thetford models?
It is designed specifically for Style II and Residence toilets. Some older models may require different bolt kits.

Q: Is this hardware stainless or rust-resistant?
Yes — the materials are designed for RV bathroom environments and resist corrosion.

Q: Does this include the flange seal?
No — the flange gasket/seal is sold separately.

Q: Will this stop my toilet from rocking?
If rocking is due to worn or broken bolts, then yes.
If the rocking is due to a damaged flange, that may require additional repair.
