Q: What is the difference between models 68005 and 66171?
A: Model 68005 utilizes the Premier Seal (mechanically expandable rubber seal), while model 66171 uses the Tape Seal (pre-compressed foam seal) for retrofit installations.

Q: Will this fit an existing 5″ drain body?
A: Yes — both models are specifically designed to fit existing 5″ drain openings in retrofit applications.

Q: Why choose a cast aluminum dome versus a plastic dome?
A: Cast aluminum domes offer enhanced durability, better resistance to impact and vandalism compared to plastic domes, making them a higher-performance choice.

Q: Is this product suitable for new construction or just for reroofing?
A: This series is designed for retrofit or reroof installations where the existing drain body remains in place; for new drain bodies swap-out, other models may be more appropriate.
