QualGear Pro-AV 1.5" Npt Threaded Pipe, Projector Accessory (QG-PRO-PM). Shows photos of outside box and the internal pieces- there are 4 total pipes. A single pipe retails for $86 before taxes on the QualGear site. I have listed these as individual pipes with volume pricing for buying more than one. If you buy the whole set, will ship in the larger outside box- if all remain. Total cost for all 4 would be just $185, getting the 4th essentially free, while at about half the cost of retail. They are all in white.
