Install. Pressure test. Knock out. Ready.
Streamline your bathroom rough-in with the LESSO ABS Closet Flange. Engineered for efficiency, this 4" x 3" toilet flange features an integrated knockout test plug that creates an immediate, airtight seal for pressure testing without requiring additional caps or balloons. Once inspections are passed, the center cap knocks out with a hammer, leaving a clean, standard opening for your toilet installation. Manufactured from durable Schedule 40 ABS, it fits over standard 3" pipe or inside 4" pipe for maximum versatility.
Features
- Integrated Test Plug: Features a moulded-in "Knockout" cap that seals the drain line immediately, allowing for water/air pressure testing and blocking sewer gas during construction.
- Easy Removal: The test cap features a scored perimeter—strike it with a hammer after inspection to remove it cleanly and open the drain for use.
- Dual-Fit Design: The hub connection is sized to fit over 3" ABS Pipe or Inside 4" ABS Pipe, making it compatible with almost any standard residential sewage rough-in.
- Adjustable Alignment: The flange ring features slotted bolt holes that allow you to rotate and align the toilet bolts precisely, even after the flange is glued down.
- Code Compliant: Manufactured by LESSO to meet CSA B181.1 and ASTM D2661 standards for drain, waste, and vent applications.
