Quick Release Top Fix Toilet Seat Hinge Base with Fixed Mount and Special Lock

Designed for repeatable fixed-position assembly, this quick release top fix toilet seat hinge base uses a dedicated Special Lock tightened from above the ceramic. The 30 mm round base is polished SUS304 and uses an M6 x 80 mm screw. It supports compatible one-button and dual-button quick release hinges for PP and UF seats. Because the lock and hinge interface must match the toilet seat and ceramic geometry, confirm drawings or samples before replacement or volume production.

Frequently Asked Questions

What distinguishes this Special Lock top fixing from other top-fix anchors?

This version uses a dedicated Special Lock component rather than a standard nylon expansion plug or metal toggle anchor. The lock is tightened from above and is intended for a matched ceramic hole, hinge interface and seat geometry.

Is the Special Lock hinge base a universal toilet seat replacement?

No. It is a fixed-position component, so the mounting-hole spacing, ceramic-hole geometry, base diameter and quick release hinge interface must match. Confirm the product drawing or send a physical sample before ordering a replacement.

What information is needed to confirm Special Lock compatibility?

Provide the toilet seat and ceramic drawings, mounting-hole spacing, hole diameter and depth, hinge interface dimensions and photos of the existing fixing. A sample is recommended when the lock profile cannot be identified from drawings.

Why use a fixed-position base for production assembly?

Once the dimensions are validated, a fixed base removes on-site hinge-position adjustment. This supports consistent alignment and a repeatable assembly process for the same toilet seat model.

Can the seat be removed without removing the Special Lock base?

With a compatible quick release hinge, the seat can be released for cleaning or servicing while the matched base remains fixed to the ceramic. The exact release action depends on the selected one-button or dual-button hinge system.

Which parts of this Special Lock assembly can be customized?

The listed configuration uses a 30 mm polished SUS304 base and an M6 x 80 mm screw. Base height, finish, color and matched locking details can be evaluated for OEM or ODM projects after drawings, samples and order requirements are reviewed.
