OATEY 42753 Full Top Grate For Floor Sink

PVC, in white. That matters for where you put it: a plastic grate handles wet mop water and typical kitchen or restroom wash-down duty, but it is not the choice for a spot taking rolling cart or forklift traffic, where a cast or nickel bronze grate belongs.

A full top grate covers the whole opening of the floor sink. A half grate leaves part of the sink open so a condensate line, ice machine drain, or indirect waste pipe can discharge into it without being pinched or cut. The Oatey 42753 is the full top version, so order it when nothing has to drop through the top and you want the entire opening screened against debris and foot traffic.

Order Oatey 42753. The manufacturer part number and the model designation are the same, 42753, and it ships as a single grate rather than a kit.

About 2.35 pounds. Light enough that one person lifts it out by hand for cleaning without tools, which is the point of a plastic top grate in a kitchen that gets scrubbed on a schedule. It is also why it should not be relied on to carry wheel loads.

PVC is the standard material for floor sink grates in food service for exactly this reason: it does not rust or corrode from the alkaline degreasers and sanitizers that get poured down these drains, unlike a plain steel grate. The white finish does show staining from coffee, grease, and food dye over time, which is cosmetic rather than structural.
