FAQs
Q: What is the difference between SKUs 68002, 66621 and 66121?
A: SKU 68002 uses the Premier Seal (mechanically expandable rubber), 66621 uses the Rubber Seal (instant compression seal), and 66121 uses the Tape Seal (pre-compressed foam tape).
Q: Will this fit a 4″ existing drain body?
A: Yes — all three models are designed to fit existing 4″ drain openings in retrofit applications.
Q: Why use a poly dome instead of a cast aluminum dome?
A: The poly dome is lighter, corrosion-resistant, and typically more cost-effective while still offering solid protection against debris and intrusion.
Q: Can this drain be used for new construction, or is it just for reroofing?
A: This series is specifically designed for reroof/retrofit installations replacing an existing drain body — for new installations, other models may be more suitable.
