The Showcase is constructed of high-quality, durable plastic, and the exterior comes with a high-gloss automotive-quality finish to deliver a decidedly more modern look. But the Showcase doesn’t just get by on appearances. The box opens from both sides, with a tapered tail to provide excellent tailgate clearance. The made-in-the-U.S. box comes with SKS locks, an intuitive push-button latch to securely close the lid and internal lid stiffeners that bolster the box’s overall strength and makes easy to open and close the lid.
Solid square load bar for kayak/canoes. It fits my 9.5 ft kayak along with my 14 canoe old town next to each other with additional space left over. It would not fit 2 kayaks and canoes flat. It does not stick out any further than mid part of side mirrors on my yukon. It is compatible with the load bar from thull. Only complaints that I noticed is that the coating is not very durable as I have a huge gash across one of the bars (not sure if from the rounded part of canoe bolt end or from combo of heat/pressure); also the rack will make a whirling noise when traveling on highways (55mph and up) which is very noticeable unless radio is on; I remove the racks during off seasons so it does not bother me at all but I can see when you may consider their additional part that blocks the wind for it from thull. I know some mentioned end caps may fall out but I have not had that issue although I put silicone (same stuff for plumbing or pool o rings) around the inside part to keep out moisture which may have helped that issue.
I don’t get this comment. With the square bars you just clamp anything straight on. With the slots you have to faff about with the plastic strip in the slot don’t you (ie. cutting it to the right size, slotting bits of it in and out in the right combination for whatever you’re putting on). Or do people not use the strip. I’m not trying to be augmentative BTW, genuinely interested I currently have square bars but am considering aero/wing bars for an imminent car change.
Secondly air pressure will try to push the boats apart from the bow. The Js are attached to the crossbar in a clamp fashion tightened with two thumb bolts. These can slide on the crossbar. The edge of your factory rail will stop them in the front, but then the rear racks will tend to slide together (toward the center of the car), making a bigger air dam. I cut and taped a strip of wood to the crossbar between the opposing rear Js so they could not slide. (I saw another car with Js and the rear racks had come together making huge air resistance and although not separated one of the kayaks had lifted from being seated in the cradle....yikes I would not want to be behind that guy!) Check all tie downs every time you stop or if you here or feel anything unusual.
Don't get me wrong. I use Thule racks and locks and cradles and locking cable and straps… the whole kit. That's because security and convenience and bicycles and protecting the roof of my car are also important, and because I started with a used Thule rack, gradually accumulating a closet full of proprietary extrapolations and substitutions as needs changed. And it does work. It all works. It's just that every single bit of it is clumsily engineered and imprecisely manufactured, requiring brute force as well as wiggling and finagling to get it just right. Some parts fit loosely, some tightly, some are robust and some flimsy. Every change, every adjustment to a Thule rack is a project and a series of compromises. Admittedly, I change things around a lot, but as familiar as I've become with my rack, I still spend an inordinate amount of time getting all the parts straight and tight and solid before I reach for my boats.
Choose aerodynamic roof bars for superior performance and a sleek, sophisticated look that complements the lines of your car. These roof rack cross bars also have many smart design features. A textured surface disturbs the airflow and greatly reduces wind noise. The aluminium extrusion creates one of the strongest load bars in the market. The design gives you quick, no-hassle installation. While the end cap pivots and T-track make it easy to add further loading options.
