American Standard Adjustable Tailpiece for 8-1/4 – 9-1/4-Inch Rough-In (6-1/8-Inch Length) - AMS-M962836

The M962836 adjustable tailpiece is built for an 8-1/4 to 9-1/4 inch rough-in, with a 6-1/8 inch tailpiece length. If your drain outlet in the wall or the distance from the sink drain down to the trap arm falls inside that window, this piece takes up the difference without cutting a new tailpiece. Outside that range you need a different length tailpiece or an extension.

Yes. M962836-0020A is American Standard's own tailpiece, so if the original drain assembly on the sink was American Standard and the rough-in falls between 8-1/4 and 9-1/4 inches, it is the direct like-for-like swap. Ordering by the manufacturer number is the safest route when a property manager needs the replacement to match the rest of the units in a building.

What you are ordering is the adjustable tailpiece itself, part M962836. The P-trap, trap arm, slip nuts and washers to tie it into the drain line are separate items, so check what is already under the sink before you pull the old one out. If you are replacing a corroded assembly, plan on a trap kit alongside it.

An adjustable tailpiece earns its place when the rough-in height is uncertain or when you are working a fleet of sinks that are not all set at the same drain height. Rather than measuring and cutting each tube, you slide this one to suit anywhere in the 8-1/4 to 9-1/4 inch rough-in range. Cutting a fixed tailpiece is fine on a one-off where you can measure the opening first, but it leaves no room to adjust if the trap arm sits higher or lower than expected.

Polished chrome, and that is the only finish offered. Since the tailpiece sits under the sink on most kitchen installs, the chrome matters mainly on exposed-trap or open-base cabinets, where it will match standard chrome P-traps and supply stops.
