Frameless Square Shower Drain Cover The Ebbe® PRO Shower Drain Cover is a 3-3/4" square cover designed exclusively for the Ebbe Square Drain Riser E4400. Its frameless profile creates a clean transition between the drain cover and surrounding grout lines without exposed screw heads. Stainless Steel Shower Drain Grate with Composite Base The PRO cover combines PVD-coated stainless steel cladding with a high-strength polycarbonate base. This composite construction provides a lightweight shower drain grate rated to support a static load of up to 1,000 pounds. 11 GPM Flow with Rounded Openings The cover provides 3.16 square inches of open drainage area and an approximate flow rate of 11 GPM, matching the flow capacity of a 2" drain pipe. Rounded openings and edges promote water passage while creating a more comfortable surface underfoot. Threaded Cover Remover for Easy Maintenance Each PRO Drain Cover includes a proprietary threaded remover for cleaning and maintenance access. Thread the remover into a corner opening and pull upward to lift the cover without exposed fasteners. Multiple finish options are available to coordinate with surrounding tile and bathroom fixtures.
