Freestanding tub drain help needed

Hello all,

I'm remodeling our bathroom, did most of the work already, but are faced with a seemingly simple task - plug a freestanding tub drain pipe to the roughed in drain in the subfloor.

The tub (http://shoprangehoods.com/other-products/bathtubs/akdy-freestanding-soaking-bathtub-abtf277.html) has integrated overflow and main drain, and came with a plastic drain pipe (see the pictures). The drain pipe screws onto the tub's drain outlet (I'm assuming I need to use tape on the thread there), but I'm confused as to how to connect the other end of the plastic pipe to the roughed in ABS 2" pipe I have prepared in the subfloor.

The tube is 30 inches long and 1.25" inch wide - and it's flexible.
Any suggestions what parts do I need to make that connection?

Any help would be appreciated!

They give you that for a drain. Make sure you can easily get to it to clear the clogs. My god the crap they put out now makes me sick

I would get a different type drain.
