Replacement Dome for 110 Series Roof Drains

This cast-iron dome strainer is a direct replacement for Jay R. Smith Mfg. Co. 110 series roof drains. It restores the original drainage opening without modifying the existing drain body. The Duco-coated finish protects the iron from corrosion in exposed rooftop conditions. Plumbers and facility managers specify it when the original dome is damaged or missing.

Installation Notes and Common Issues

The dome sits on the drain body and secures with the existing hardware, so no special tools are required. Verify that the drain body matches the 110 series before ordering, as other series use different dome dimensions. A frequent problem is debris buildup under the dome lip, which reduces flow until cleared. Ensure the flashing clamp is tight after installation to prevent leaks.

Critical Compatibility Specification

This dome fits only Jay R. Smith Mfg. Co. 110 series roof drains. The overall diameter is 6 5/8 inches and the overall height is 6 inches. It will not fit other manufacturers' drains or other series from the same brand. Confirm the drain body model number before purchase to avoid returns.

  • Duco-coated finish resists corrosion on exposed drains
  • 6-inch height fits series 110 roof-drain bodies

Questions about this item

How do I confirm the dome strainer is seated correctly after installing it on the 110 series roof drain body?

The replacement dome fits the Jay R. Smith 110 series; once bolted down the Duco-coated cast iron dome should sit flush with the 6 5/8 in diameter opening and the 6 in overall height matches the original profile.

What components are included and what must be sourced separately for a complete installation?

The package supplies the Duco-coated cast iron dome strainer with a 6 5/8 in overall diameter and 6 in height; the 110 series drain body, flashing clamp, hardware and any required pipe adapters are sold separately.

Which version should I select to match my existing Jay R. Smith 110 series roof drain?

Choose the 110-10 model — it is listed as compatible with Manufacturer Model Number 110, Series 110 and the Jay R. Smith MFG. Co brand, providing a 6 5/8 in round cast iron dome for that specific drain body.
