The flush design keeps the crossbars tight to the roofline for a clean, from-the-factory look. The bars don’t stick out past the feet, so the setup looks intentional and streamlined. The Thule WingBar Edge sits low and neat, giving your roof rack a built-in appearance that blends in with the shape of your vehicle.
Wind noise can make long drives tiring, but these aero-style crossbars are shaped to help reduce drag and vibration. The top channels include split rubber strips that let you easily slide in accessories without trimming, while also sealing the channel to minimize whistling. It’s a setup that keeps things quiet and smooth on the highway.
Whether you’re hauling kayaks, canoes, or loading up a cargo box for a road trip, these bars handle it all. They work with most bike, watersport, snow, and cargo carriers that mount in top channels or clamp around the bars. That means you can use your favorite attachments year-round without needing different setups.
Each bar is built from durable aluminum for strength without unnecessary weight. With a 165 lb weight capacity (always check your vehicle’s maximum roof load), the system is ready for heavy gear like watercraft or camping supplies. Bar dimensions are 37-1/2" long x 3-1/8" wide x 1" tall and 41" long x 3-1/8" wide x 1" tall, giving you solid surface space for mounting accessories.
You can upgrade security by adding Thule One-Key System locks (sold separately). These locks deter theft of both the rack and your channel-mounted gear. It’s an easy add-on that keeps your setup protected when you’re parked overnight or away from your vehicle.

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.
