The Arch Top Fixing Base Set is a complete toilet seat mounting solution consisting of the upper decorative base system and lower top fixing components. The arch-type locking structure allows installation entirely from the top side of the ceramic bowl, eliminating the need to access the underside during assembly.
Compared with traditional bottom fixing systems, this solution offers faster installation, improved user convenience, and greater compatibility with modern toilet designs. The stainless steel cover enhances product appearance while protecting internal mounting components.
The system can be customized with different base diameters, cover finishes, hinge pin structures, screw specifications, and fixing configurations to match various toilet seat hinge and damper systems.
