Thanks for posting that and yep looks like what mine came with. I bookmarked them in case I need some later. I love how they lock into the rails by twisting them. Heck of a lot easier than if you had to slide in from the rail end like I had dealt with on a rail setup years ago.I did find some compatible brackets. One of the reviews said these are almost identical (just a little longer). I plan to probably get two more of the racks, so this 10 pack will work out fine.
