A quick learner from Californai says:
Do they come in a 2 pack or single. I need all 4 rollers or a closet and I want to know if I need to buy 2 of each or 1. It doesn't say if it's a single or 2 to the pack

Thanks for posting. The 23-178 roller is sold individually, not in pairs. I hope that clears things up.

23-178 : Rear Bypass Hanger, 1-1/2
