The flush design keeps the crossbars tight to the roofline for a clean, factory-style appearance. Nothing sticks out past the feet, so the rack looks built in rather than added on. With its aerodynamic shape and aluminum construction, it blends right in and keeps things low and sleek on top of your vehicle.
Driving with crossbars can create wind noise, but these bars help keep things quiet. The aero-style shape reduces drag, and the split rubber strips in the top channels let air flow smoothly while helping to cut down on vibration and whistling. It’s a noticeable improvement for highway trips and long drives.
This setup is ready for whatever adventure you have planned. Bring kayaks, cargo boxes, or snow gear—the WingBar Edge works with both channel-mount and clamp-on accessories. The top channels make it easy to slide mounts into place, and there’s no trimming needed thanks to the split strip design. You can swap attachments quickly without extra hassle.
The aluminum bars are built to handle up to 165 lbs while keeping weight off the roof itself. That strength means you can confidently load up heavy gear without worrying about flex or instability. The sturdy build keeps your cargo secure across highways or bumpy backroads alike.
You can upgrade this rack with Thule One-Key System locks (sold separately) to secure both the rack and your mounted accessories. It’s an easy way to give yourself peace of mind when you leave your setup unattended at camp or during travel stops.

I agree with you that the rack should include the keys however Thule only offers the one lock system separately as part # TH450400 for a 4 pack. They do it this way so that if you have other Thule accessories like a Thule kayak or bike carrier then you can have the option of ordering enough keys to swap them all out to key them the same. For example you can also buy a six part part # TH450600 or an eight pack like part # TH450800.

Congrats on your new Benz! Sounds like a fun and exciting Christmas morning. I'm only slightly jealous of that tandem bike, I've always wanted to ride one.
