Jr Smith 1010CID Dome Strainer

The Jr Smith 1010CID dome strainer is a cast iron component designed for roof drainage systems. It fits flanged drain installations where a slotted grate surface is required. The unit includes a replacement dome for maintenance purposes.

Cast iron construction handles continuous exposure

Cast iron construction handles continuous exposure to weather and roof runoff without deformation. The Duco coated finish provides a protective layer against corrosion during sustained wet conditions. The slotted grate pattern allows water passage while blocking debris over long service intervals.

Replaces worn domes on compatible roof drains

This strainer replaces worn or damaged domes on compatible round roof drains with bottom outlets. The upgrade is worth it when the existing grate shows corrosion, cracking, or slot deformation that impedes drainage flow. It is not suited for floor drains, area drains, or non-flanged connection types.

Questions about this item

How much heat does the cast iron dome strainer generate during continuous rooftop exposure?

The cast iron construction with Duco coating does not generate heat; it simply withstands ambient rooftop temperatures and solar gain.

What existing drain body must I already have for the 1010CID dome strainer to fit?

It installs on a flanged round roof drain body with a bottom outlet that accepts an 11 1/8 in diameter flanged grate.

Will the slotted grate surface handle debris the same way as an older perforated dome I might keep nearby?

The slotted grate surface passes water differently than perforated types, so debris capture and flow characteristics will not match an older perforated dome.
