I ran the Carlon 2" flexible pipe to my projector. It's called Carlon Resi-Guard Flexible Raceway - 2" Diameter. I couldn't find it locally either, so had to order online. If you do a search on the above name, you'll find several websites that sell the product.
Here's the link to one of the websites:

You'll see the tubing about halfway down the page.
