Abstract
Various embodiments for a drain debris straining assembly are described, where the drain debris straining assembly can be positioned inside a drain to collect hair and other debris. A drain debris straining assembly in accordance with an embodiment of the present application includes a basket assembly. The basket assembly includes a basket body surrounding a hollow core and at least one opening configured to filter fluid to entrap debris. The basket assembly further includes a flexible rib configured to compress against an internal diameter of a drain flange to form a seal between the basket assembly and the drain flange. The drain debris straining assembly may also include a pop-up assembly having an interference ridge sized and positioned to contact at least one inner wall of the basket assembly to retain a vertical position of the pop-up assembly relative to the basket assembly.
