The flush design keeps the crossbars tight to the roofline, giving your setup a sleek, from-the-factory style. Nothing extends past the feet, so the rack looks integrated instead of tacked on. The WingBar Edge has that clean, low-profile look that blends right in while still giving you the strength and utility you need.
Long drives can get noisy when wind catches the bars, but these aero-style crossbars help keep things quiet. The aerodynamic shape reduces drag, and the split rubber strips in the top channel seal around your accessories to cut down on wind noise and vibration. You’ll notice smoother airflow and fewer distractions while driving.
Whether you’re hauling kayaks, canoes, cargo boxes, or skis, these bars have you covered. They work with accessories that mount in the top channels or clamp around the bars, so you can use your existing gear or mix it up for different seasons. The flexible mounting options make it easy to get your gear on the road.
Some racks make you cut rubber inserts before sliding in mounts—these don’t. The split strips let you slide accessories right into the track without trimming, then close back up to protect against wind and weather. It’s a small detail that makes installing and adjusting your gear easier every time.
You can upgrade with Thule’s One-Key System locks (sold separately) to secure both the rack and any channel-mounted accessories. It’s a quick way to add peace of mind when you leave your vehicle parked overnight or at a trailhead.
Crossbar dimensions 30-1/2" long x 3-1/8" wide x 1" tall; top channel 3/4" wide x 1/8" tall x 3/8" opening; weight capacity 165 lbs; color black; aluminum construction; limited lifetime warranty.

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.
