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 blends cleanly into the vehicle’s profile. The WingBar Edge design keeps things compact and balanced for a low-profile appearance without sacrificing performance.
Driving with roof bars can sometimes bring annoying noise, but these aluminum aero-style crossbars are built to keep that in check. The aerodynamic shape helps smooth airflow, while split rubber strips in the top channels fill the gaps to reduce wind noise and vibration. You get a quieter ride and a cleaner look all in one.
This rack is ready for whatever you’re hauling. The crossbars work with both channel-mount and clamp-on accessories, so you can load up bikes, skis, kayaks, or a rooftop box without needing special adapters. The top channels make it easy to slide your mounts into place—no extra trimming or modification required.
With a 165-lb weight capacity and sturdy aluminum construction, these bars stay solid under heavy loads like cargo boxes or outdoor gear. They mount securely to raised rails for confident hauling on long trips. The silver finish keeps things looking sharp while handling miles of use season after season.
You can add Thule One-Key System locks (sold separately) to deter theft of the rack and any channel-mount accessories. It’s an easy upgrade that gives you peace of mind when you leave your setup parked overnight or at the trailhead.

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.
