American Standard FloWise 12-Inch Rough Tank Cover with Locking - AMS-7381034-200

It's matched to the FloWise dual flush model built for a 12-inch (305mm) rough-in with a top mounted push button actuator. Tank lids are model specific, so measure your rough-in from the finished wall to the closet bolts and confirm your tank uses a top push button rather than a side or front trip lever. A trip lever tank takes a different cover.

The cover is specified with the chrome-plated top mounted push button actuator that operates the dual flush valve. That button is what makes the lid model specific: it has to line up with the flush valve below it, which is why a generic lid won't work on a FloWise dual flush tank.

The FloWise dual flush fixture runs 1.6 gpf/6.0 Lpf on a full flush and 0.8 gpf/3.0 Lpf on a partial, using 33 percent less water, and it meets EPA WaterSense criteria. That's useful if you're confirming you're buying the lid for the dual flush version and not a single flush tank, since the two use different covers and actuators.

A locking lid keeps the tank closed in public and semi-public restrooms, which stops tampering with the flush valve and stops lids getting knocked off and broken. For multi-family and commercial washrooms where the same FloWise dual flush fixture is repeated across a building, standardizing on the locking cover means one replacement part for every opening.

White is the finish offered, MPN 7381034-200.020. Match it against the tank you already have, because white bodies from different eras and different manufacturers won't always be a visual match side by side.

The fixture is a Right Height elongated wash down bowl with a 16-1/2 inch (419mm) rim height. Rim height is measured without the seat, so the finished seat height lands higher than that figure once a seat is fitted.
