I need to plumb into an existing ABS drain, labelled as "ABS/DWV 1 1/4" schedule 40 ", but for the life of me cant find any 1 1/4" fittings!!!
My suspicion is that the pipe is 1 1/4" ID, and I need to buy 1 1/2" OD fittings.
Before I trundle down to Home Depot, is anyone able to confirm my suspicion (or do I have the most useless, redundant piping ever?
Thanks!

They definitely exist (in Canada at least).
Sample "big box" listing for "abs 1 1/4" :
