When you say the toilet’s “handle”, im assuming you’re talking about the “trip lever”?
(“Toilet handle” is a common “term” used by a home owner/handyman etc...)
Over the last few years, it’s been very hard to find trip levers, that fit snug into an OG “toilets tank’s TL opening” - that actually fit without alot of play. Newer TL’s need to be shimmed to operate properly, which is a hassle!
(A lot of W/C tanks have a large rounded square opening for their TLs, which a lot of off the shelf TL’s don’t fit. They have a smaller square- that is loose in the tanks larger opening.)
Solution:
“Fluidmaster’s Perfect fit” universal trip lever, seems to be the most “universal fitting” TL on the market in my opinion, they are multi adjustable in X/Y/Z plains and in length.
At about $20, they’re worth the $ and save time the a big hassle.
