American Standard 8447.311800.075 – Frequently Asked Questions

1) Which American Standard sink does the Portsmouth 8447.3118 bottom grid fit?
The Portsmouth bottom sink grid is engineered for the Portsmouth 18DB.9311800S.075 double bowl kitchen sink. It fits a bowl measuring 14-3/4 inches wide, 16-5/8 inches front to back, and 9 inches deep. If your bowl interior does not match those three numbers, the grid will either rock on the radius or sit proud of the drain.
2) Does one box of the Portsmouth 32 x 18 sink grid cover both bowls of a double bowl sink?
No. One grid ships per box, so a double bowl Portsmouth sink needs two orders if you want protection in both bowls. Property managers doing a run of units should double their count accordingly.
3) I have a Portsmouth kitchen sink but I am not sure of the bowl size. How do I check before ordering the grid?
Measure the inside of the bowl at the bottom, not the countertop cutout. The grid is sized for a bowl 14-3/4 inches wide by 16-5/8 inches front to back with a 9 inch depth. The 32 x 18 in the name refers to the overall Portsmouth sink, not the grid itself, so comparing outside sink dimensions will mislead you.
4) Is this Portsmouth sink grid rated for a commercial kitchen?
No. American Standard classifies the Portsmouth grid as a residential kitchen accessory. For a restaurant line or an institutional dish area, spec a commercial-duty grid instead; this one is intended for residential and multi-family unit kitchens.
5) Is a bottom sink grid the same thing as a sink strainer or drain assembly?
No, and they are not interchangeable. The Portsmouth 8447.3118 is a bottom grid: a rack that drops loose into the bowl to keep cookware off the sink floor. It does not seal, does not thread into the drain opening, and does not replace a basket strainer or the drain assembly. You still need the strainer and tailpiece to complete the sink.
