This toilet seat won't come loose or move while in use as the toilet seat hinges are glued into place with a high strength adhesive. The hinges can be adjusted to suit fixing hole centres from 110mm to 200mm. Using double fix solution where fixings are glued and screwed means it's ready to use straight away - just fit and forget.
