Secure a loose or unstable toilet seat with the NovaCart 2-Piece Top-Fixing Toilet Seat Bolt and Expansion Sleeve Kit.
This practical replacement set is designed for selected toilet seats that are installed from above. Each fixing assembly includes a flexible rubber expansion sleeve, metal screw and washer. As the screw is tightened, the sleeve expands inside the toilet mounting hole to help create a firm and stable hold.
The kit is suitable for replacing worn, damaged, missing or loose toilet-seat fittings without requiring access underneath the toilet pan. Its compact design makes it a convenient repair solution for compatible household toilets, rental properties, guesthouses and maintenance applications.
Because toilet-seat fittings vary, customers should compare the product dimensions and mounting style with their existing hardware before ordering.
