American Standard 8459.301800.075 – Frequently Asked Questions

1) Which American Standard sink does the Portsmouth 30 x 18 bottom grid fit?
The Portsmouth bottom sink grid is engineered for the Portsmouth 18SB.9301800S.075 single bowl sink. It suits a bowl measuring 27-3/4 inches (705mm) wide, 16-1/4 inches (413mm) front to back, and 9 inches (229mm) deep. If your bowl interior differs from those numbers, the grid will either rock on the radius or sit short of the walls, so measure the bowl itself rather than going by the 30 x 18 sink name.
2) Will this sink grid protect the bottom of my stainless sink from scratches?
That is what it is built for. The grid comes with bottom feet that hold it off the sink floor and side bumpers that keep the frame from contacting the bowl walls, so pots and cast iron cookware land on the grid instead of the finish. For a rental or a high use kitchen it is the cheapest way to keep the bowl bottom from looking beaten up.
3) Do I need any hardware or tools to install this sink grid?
No install work at all. The Portsmouth grid is a drop in accessory that sits on its own feet in the bowl, with side bumpers positioning it against the walls. Nothing mounts, drills, or fastens, so it can be added to an existing sink at any time.
4) What finish and material is the American Standard 8459.3018 bottom grid?
Stainless steel is the only finish offered, under part number 8459.301800.075. That keeps it visually consistent inside a stainless bowl and avoids any coated finish that chips when a pan drops on it.
