2.5 tri adapter

[ApesUpt]

So I would like to know if there is a mod out there that has dual, tri, and quad adapters for 2.5+ parts. I feel it would be very useful to use these.

I highly recommend SpaceY Heavy Lifters:

Among other things, it includes a lot of really handy interstage thrust plates in various sizes.  They're not exactly the bi/tri/quad adapters you're looking for, but you can achieve pretty much the same effect by adding an adapter that goes from 2.5m up to 5m, and then a thrust plate with 2.5m nodes on it.

Novapunch has some larger adapters in it. Not on my PC ATM so I can't say for sure which ones or sizes but I know it has some that can handle more than 4 motors and it also has some tri, quad and 5 engine bell motors too. Hope this helps
