Jr Smith 1330D Dome Strainer Polyethylene 6 5/8 in Gray

SKU CH-7KJ1-JKFK4

Polyethylene dome strainer fits 1310 and 1320 roof drains with a 6 5/8 in diameter and slotted grate surface

  • Polyethylene construction resists corrosion for long service life
  • 6 5/8 in diameter fits 1310 and 1320 roof drains
  • Flanged installation enables secure mounting on roof drains
  • Slotted grate surface allows water flow while blocking debris
  • Meets ASME A112.6.4-2003 and CSA B79-2008 standards

Product Purpose

The Jr Smith 1330D is a replacement dome strainer designed for 1310 and 1320 roof drain assemblies. Its polyethylene construction resists corrosion and provides a slotted surface to filter debris while allowing water flow. The unit installs via a flanged connection and meets ASME A 112.6. 4-2003 and CSA B79-2008 standards for roof drainage components.

Ideal Applications

This strainer suits maintenance teams replacing damaged domes on compatible Jay R. Smith roof drains where a 6 5/8 inch diameter fits the existing flange. It is not for installers needing an ADA compliant grate or a load rated cover for pedestrian traffic areas. Buyers requiring a different diameter, a metal finish, or a non flanged mounting method should look at other drain accessories.

Deciding Specification

The overall diameter of 6 5/8 inches and the compatible model numbers 1310 and 1320 determine whether this dome matches the installed drain body. Verify the existing drain model and flange dimensions before ordering to ensure proper fit and drainage performance.

Questions about this item

How is the 1330D dome strainer installed and what step is often missed?

It uses a flanged installation onto compatible 1310 or 1320 roof drains; the step often missed is confirming the drain model matches before mounting.

What maintenance or replacement will the polyethylene dome need later?

The product includes a replacement dome; swap it when the slotted grate shows cracking or UV degradation from rooftop exposure.

What limit appears first under sustained rooftop use?

The polyethylene material will reach its UV and thermal limit before the ASME A 112.6. 4-2003 (R08) or CSA B79-2008 (R2013) structural ratings are tested.
