Their roof rack is made out of tubed steel. It’s moderately heavy at 35 lbs. This will attach to your cross bars with included mounting hardware. Leader Accessories uses U-bolts.
If you ever plan on having items that can shift, picking up some bungee cords or a cargo net will be a worthwhile addition. One caveat of this purchase is that you, like us, might be a bit annoyed with the logo of “roof rack” printed on the front.
We don’t really get the whole purpose with that.. but outside of visuals this is a well made piece of equipment.
