A: Not sure what you mean by universal toilet. This works on the left side of the tank and I have used this on several brands of toilets.
A: Yes, they delivered it today. I installed it in under an hour. Works great.
A: This product is designed to fit most toilets, we are unable to verify at this time if it will fit your specific model. Thank you.
A: Hello Tala, The rod arm should be removable to switch the handing. I hope this helps. Cheers, Chris
A: Mine mounted on left when facing the tank. Not sure if the spring mechanism in the handle would accommodate installing in right side. Would mean one would lift handle to flush, and not push down as normal. If okay with lifting, it may be possible. If doesn’t work, could return to store probably.
A: Don't know those numbers - went to Kohler's web site, plugged each of them in their search engine but nothing returned except for the K 4520 DA and it just returned 4 of their handles. I use the handle with Kohler's Devonshire toilet & Kohler's Memoir toilet. Works well - better than the original handle & looks great. With what Kohler toilet model are you wanting this handle to work?
