Abstract:

A light-weight, liquid-blocking ring assembly for a surface drain for preventing a harmful liquid spilled nearby from entering the drain, which can be quickly and easily installed by a single person, and includes positive verification that none of the undesired liquid has entered the drain. The assembly includes 1 a center portion having a latching mechanism for attaching and drawing the assembly towards the drain, 2 a peripheral band which surrounds and is spaced from the drain, and which carries at its bottom edge a resilient gasket conformable to the surface surrounding the drain, and 3 an intermediate structure connecting the center portion and the peripheral band without blocking a clear view of the entire surface surrounding the drain.
