FAQs
Q: What is the difference between 68003, 66661 and 66161?
A: Model 68003 uses the Premier Seal (mechanically expandable rubber), model 66661 uses the Rubber Seal (compression gasket), and model 66161 uses the Tape Seal (pre-compressed foam tape) for retrofit applications.

Q: Why choose the aluminum dome strainer version?
A: The cast-aluminum dome strainer offers superior durability and resistance to impact and vandalism compared with plastic dome versions.
Q: Is this product only for new installations or also for reroof/retrofit jobs?
A: This series is specifically engineered for retrofit or reroof installations where the existing drain body remains in place.
