This kit is designed for most standard toilet seats that use bolt-style fixings. It's important to check your toilet pan hole size compatibility (14–19 mm).

Clean the fixings with a soft, damp cloth. Avoid using harsh or abrasive cleaning chemicals.

Dual fixing means the kit provides components and instructions for two different installation methods: top fixing (where fixings are inserted from above) and bottom fixing (where fixings are inserted from below).

Ensure all nuts and screws are fully tightened. Check that the toilet pan hole size is within the 14–19 mm range. Verify that the toilet seat hinges are properly seated on the fixings.

Confirm that you are using the correct part of the kit (e.g., steel screws for specific top-fix designs, plastic nuts for bolts). Measure your toilet pan hole size to ensure it falls within the 14–19 mm range.

Ensure the holes are clean and free of debris. If using bottom fixings, make sure the bolt is correctly aligned with the hole from underneath. Gentle pressure may be needed, but avoid forcing.
