American Standard Cadet 3 Toilet Tank Cover - AMS-735121-400

The 735121-400 lid is the flat tank cover for the Cadet 3 close-coupled tank, so it is the correct replacement where that tank is installed. Match the model number cast or stamped inside your existing tank before ordering, because American Standard tank lids are tank-specific and a lid from an adjacent Cadet tank will not seat correctly.

Three colors: White (735121-400.020), Bone (735121-400.021) and Linen (735121-400.222). American Standard color codes are printed inside the tank on most units, so the fastest match for a property manager working across a building is to pull one lid and read the suffix rather than eyeballing the china against a sample.

No. The tank cover is sold on its own, so a cracked or dropped lid is a lid replacement, not a tank replacement. Nothing on the flush side is attached to it: the Cadet 3 uses a chrome-plated trip lever mounted through the tank wall and a 3 inch flush valve, both of which stay put when the cover comes off.

Just the china lid. The trip lever, flush valve, fill valve and the Speed Connect tank-to-bowl coupling hardware are all separate parts that stay with the tank. If the handle is what failed, you need a Cadet 3 trip lever, not the cover.

Lift the existing lid and look inside the tank at the back wall, where American Standard casts the model number and date. Cadet 3 tanks pair with a siphon action jetted bowl with a fully glazed 2-1/8 inch trapway and a 9 x 8 inch water surface; a two-piece close-coupled tank with a flat, squared-off lid is the visual tell. Round-front and elongated Cadet 3 bowls use the same tank, so bowl shape does not change the lid you need.

Yes, it carries the same EverClean surface as the fixture, which is the glaze treatment American Standard uses across the Cadet 3 line. For a housekeeping crew wiping tanks daily in a hotel or a multi-family building, that means the replacement lid cleans the same way as the ones already installed and will not read as a different sheen next to them.

Lids are the most commonly broken part of a toilet in high-traffic and turnover properties, and they are the one part you cannot fabricate on site. If your fixtures are standard White, stock 735121-400.020; Bone and Linen units need their own matching suffix, since colored china cannot be substituted with white. Counting fixtures by color once and stocking to that count is cheaper than a per-incident order later.
