OATEY 760W-1 Dearborn® Semi-Cast Grid Wheelchair Patent Overflow Plug w/ 1-1/4 in. - 17 Ga. Tailpiece

The 760W-1 ships as a complete lavatory drain assembly: a semi-cast open grid strainer, the PO (patent overflow) plug body with its nuts and washers, a 90 degree elbow, and a 1-1/4 inch by 6 inch 17 gauge tailpiece. That means you have everything from the sink opening down to the trap connection. You still supply the P-trap itself and the plumber's putty or sealant at the strainer.

Knee clearance. On an ADA-style lavatory the user's legs go under the bowl, so the waste has to turn back toward the wall instead of hanging straight down in front. The 760W-1 uses a 90 degree elbow off the drain body and then a 6 inch tailpiece to carry the outlet back out of the knee space. A standard straight PO plug drain drops vertically and eats the clearance a wheelchair user needs.

It is built for one. PO stands for patent overflow, meaning the drain body is ported so water entering the lavatory's overflow channel passes through the body and down the drain. It uses a sloped gasket at the bottom of the body to seal against the underside of the bowl. Do not use a PO-style drain on a basin with no overflow, that needs a non-overflow (grid only) drain.

Open grid, with no pop-up stopper and no lift rod. The strainer is a semi-cast open grid, which is what you want on a public or accessible lavatory where the sink shouldn't be filled and there's no mechanism for a user to operate. If your fixture is spec'd for a pop-up with a lift rod, this is the wrong drain.

It carries a cUPC listing, which covers the Uniform Plumbing Code in the US and Canada, so it will pass inspection on commercial, healthcare, school, and multi-family lavatory work where UPC applies.

Brass body with a plated chrome finish. Brass is what facilities buyers spec over plastic in public restrooms because the strainer takes abuse and the threads survive repeated trap service. The chrome plating matches the exposed chrome supplies and traps typically used on accessible lavatories.
