American Standard Adjustable Tailpiece for 6-1/4 – 7-1/4-Inch Rough-In (4-1/8-Inch Length) - AMS-M962834

The M962834 adjustable tailpiece is built for a 6-1/4 to 7-1/4 inch rough-in, with a 4-1/8 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 is the piece that takes up the slack without cutting a fixed tailpiece to length.

It is the vertical section between the sink strainer or drain body and the P-trap. The American Standard M962834 is a drain assembly component for sink applications, so it goes in when the existing tailpiece is too short, too long, or corroded, not when the trap itself is the problem. If the leak is at the trap bend or the trap arm going into the wall, you need a trap kit instead.

Order it as American Standard M962834-0020A. The M962834 is the base part and the -0020A suffix is the polished chrome finish code. That is the number to put on a purchase order or give to a counter.

No. The M962834 is the tailpiece only. You supply the P-trap, the slip nuts and washers at each joint, and the sink strainer or drain body it threads up to. Plan on having a trap kit or loose slip washers on the truck before you pull the old one out.

Use the adjustable version when the drain outlet height is off from the trap and you want the fit dialed in without a hacksaw, or when you are working a fleet of sinks where the rough-in varies unit to unit. The American Standard M962834 telescopes across a 6-1/4 to 7-1/4 inch rough-in. A plain flanged tailpiece is fine when the rough-in is known and repeatable; it is one less slip joint to leak.

It ships in polished chrome, which is the standard finish for exposed P-traps, supply stops and escutcheons under a sink. On an exposed-plumbing job (pedestal lav, wall-hung sink, open vanity), that keeps the run uniform. Chrome is the only finish this tailpiece is offered in.
