American Standard Cardiff Slow-Close Round Front Toilet Seat - AMS-5259B65MT

The Cardiff 5259B65MT is a round front seat and fits most conventional round front toilet bowls. Round front is the shorter bowl shape, roughly 16-1/2 inches from the bolt holes to the front rim, versus about 18-1/2 inches on an elongated bowl. If the bowl you are replacing on is elongated, this seat will sit short and you need an elongated seat instead.

Mounting hardware is in the box. The Cardiff seat uses bottom mounting hardware with a quick connect nut, so you set the seat, drop the bolts through the bowl holes and tighten from underneath without a second person holding the top. No separate bolt kit to order.

For units where slammed lids are cracking seats and generating service calls, yes. The Cardiff's No Slam mechanism lets the seat and lid lower under their own weight instead of dropping, which is the main cause of hinge and lid breakage in high-turnover housing. Note this is an American Standard residential-line seat, so it suits apartments, condos and single family units rather than heavy commercial restroom traffic.

Polypropylene plastic with an EverClean antimicrobial surface. The antimicrobial treatment is built into the surface to inhibit the growth of stain and odor causing bacteria, mold and mildew on the seat itself. Polypropylene takes standard bathroom cleaners without the finish crazing the way a painted wood seat does.

Yes, and that is the point of the quick connect nut. The bolts feed from the top and the nut engages from below the bowl without reaching up behind the tank or holding a bolt head steady on top. For a maintenance tech doing several units in a day it is a few minutes per bowl with a standard wrench.

The Cardiff seat is 3.283 lb each. Carton dimensions run 18.813 x 14.688 x 2.688 inches, so a pallet buy of seats stacks flat and predictably, which matters if you are standardizing seats across a portfolio and ordering by the case.
