Understand the application
Define the load, movement, installation space and interface before selecting a model.

Coordinate the seat outline, fixing centres and hinge system for a comfortable, well-fitting bathroom product.
A bathroom product needs more than a similar outline. Check the overall seat length and width, fixing centres, hinge access and the way the seat and lid sit on the ceramic bowl. A close visual match should be followed by a dimensional check.
For a soft-close project, discuss the seat and lid separately: their weights and centres of gravity affect the component choice. For a replacement programme, record the existing fixing system and bowl dimensions before selecting a model.
Define the load, movement, installation space and interface before selecting a model.
Review dimensions and published torque, then identify the configuration to sample.
Check movement in the real product rather than relying on a component dimension alone.
Confirm the selected variant, inspection needs, packaging and commercial terms.
