The BSC PREFERRED DIB811-35 is a chrome-plated split floor and ceiling flange designed for 1-1/2 inch IPS pipe applications. It covers exposed holes where sink drain pipes pass through floors or ceilings, providing a clean, finished appearance in visible installations. The hinged split-plate design allows installation without removing the pipe from the wall or floor assembly. A snap closure holds the flange securely in place once set. Constructed of chrome-plated metal, it delivers a high-luster finish suited for exposed residential and light commercial plumbing installations. Plumbers and finish trades install this flange as a final trim step after rough-in is complete.
This flange is used in residential and light commercial settings wherever a 1-1/2 inch IPS drain pipe penetrates a floor or ceiling surface and the surrounding hole needs to be concealed. Common applications include under-sink drain rough-ins, lavatory installations, and kitchen sink drain tie-ins where the pipe is visible at the floor or ceiling plane. The split-plate construction is especially useful during remodel work where the pipe is already set and cannot be removed for a one-piece flange.
Designed as an OEM-style trim fitting for 1-1/2 inch IPS drain pipe penetrations in residential and light commercial floor and ceiling applications.
Installation is performed by licensed plumbers or finish trade professionals as part of drain trim-out. Shut off water supply and ensure the drain pipe is clean and dry before fitting the flange. Open the hinged plate around the pipe at the floor or ceiling surface, align the flange, and engage the snap closure. No pipe removal is required, making this a straightforward retrofit or remodel installation.
