Anyone know the specs of the Gobi Cross Bars?

I ordered a SB GEN2 RTT and looking to buy some mounts like these

Roof Top Tent Mounts - GZila Designs


But not 100% sure of the cross bar size. Thanks in advance

I don't know the size either, but if it helps, Gobi makes something very similar for their racks (so you don't have to know the size):

Was thinking of getting the same clamps so I just measured using Gzila's clamp size ruler. Unfortunately the Gobi Crossbars are a bit bigger than 1.125" so I'm not sure these would be compatible. I'm going to reach out to Greg just to be sure and I'll report back.
