IIRC, slightly more than 1.9" (OD of Sc40 1.5" PVC).
Going into further detail, we then wrap the 1.5" PVC with shelf liner. We create our spacers/grooves by using rings of 2" PVC over that assembly.
We used this approach in 2009, 2012 and 2013, and were largely happy with it. We still get some amount of wandering polycord, but it's not really a big deal.
