What is the unobstructed open edge of a fixture called?

Explanation:
The unobstructed open edge of a fixture is called the rim. The rim is the outer edge around the top opening of a sink, basin, or similar fixture, and it defines the boundary where the fixture meets the surrounding surface or mounting. A lip is a projecting edge and isn’t the open edge itself, a bead is a small rounded ridge used for styling or sealing, and a spout is the water outlet rather than the edge of the opening. So rim is the right term for that edge.
