Abstract: A strainer for installation on a drain outlet of a container, such as an ice chest, has a housing including a backing plate and a cover, and a tubular drain engagement member releasably connected to the backing plate. The housing may be installed either by connecting the drain engagement member to the backing plate and fitting the tubular drain engagement member into the drain outlet, or by removing the tubular drain engagement member from the backing plate, securing the backing plate over the drain outlet with a nut, and installing the cover onto the backing plate to cover the drain outlet. The housing has a plurality of apertures formed therethrough in communication with the interior of the housing that allow liquid to pass through the drain outlet, while effectively preventing various sizes, shapes and types of debris from entering and clogging the drain outlet.
