I do have a solution for you but it isn't anything from either of the other roof racks.

What you can use is the QM3 hardware # TH04997. The QM3 will work with your 2015 Chevrolet Suburban's factory roof rack but you'll need to drill some holes in the Summit cargo box to use it.

Unfortunately, there isn't hardware specifically designed for the Summit that will work on the Suburban's crossbars.
