2015+ GM roof rails

I might be interested in these. What are the top mounts on the rails like? Specifically, what process do cargo boxes or ski racks mount to the rails via? Is it a GM proprietary mount or more of a universal bolt setup?

those are the cross rails, the roof rails should already be on your vehicle, some may not have them.
these cross rails mount in 2 separate locations only on the roof with bolts, they do not slide front too back. so 2 settings only (look at your roof for reference).
ALSO technically this person is not supposed to be selling these on here, there is a classified section for MEMBERS to sell things on once a minimum amount of legit postings are made around 85 or so.
SO BUYER BEWARE, do not send money to anyone without a legit invoice being sent to you from say paypal, etc so you are covered in case of scammer.
a fool and his money are soon parted..........

Thanks. My terminology was sub par. I have the factory "rails" on my tahoe. I was asking about how do boxes etc. mount to the cross bars/rails? Is that GM proprietary or could any Thule or Yakima cargo box be mounted without much pain? Hope that makes sense...
