Mounting Base for Ebbe Drain Covers The Ebbe® Square Drain Riser serves as the mounting base for all Ebbe Pro and Ebbe Unique drain covers. Its square profile allows straight tile cuts around the drain opening, eliminating the need for circular cuts and simplifying tile layout during installation. Frameless Design with Secure Installation The drain riser features a frameless ABS construction with undercut grout-locking features to help create a secure installation. It threads directly into many common 2" drain bodies, making it suitable for new installations and compatible drain replacements. Includes Hair Trap and Construction Plug Each Square Drain Riser includes an Ebbe Hair Trap and Construction Plug for installation and drain maintenance. It is compatible with drain bodies from Sioux Chief, Plastic Oddities, IPS, Jones Stephens, Frank Pattern, Thunderbird, Oatey, Pasco Specialty, ProFlow, and many other 2" drain body manufacturers.
