Levier de déclenchement à droite 738171-0020A

Easy to install, works perfectly.

It was the wrong part -- my fault: I needed a left-hand one. But it also came two days after the date Wayfair had sent.

Lift lever is on upside down - chain attaches from the top, not the bottom. Square area inside handle is not aligned correctly, so it cannot fit into the toilet tank at correct angle I was able to purchase one from a local plumbing supply house (it was previously thought they did not carry what I needed)
