Cargo box clips for roof rack

[itripn]

I recently installed a Prospeed roof rack on my R1S, and am loving it. Around the same time I found myself collecting some Harbor Freight cargo boxes that were cheap, and stackable, and I thought would make good camping/overlanding storage solutions.

I then realized I might be able to mount them on the roof rack to free some space up inside the vehicle. Since they stack, they have small cavities on each side at the bottom where the clips from the top of a box below can click into in order to securely stack multiple boxes.

Running with that, I prototyped some clips with my 3D printer (white in the attached photo), and once I got them where I wanted had PCB Way CNC and anodize some aluminum versions (from the same 3D model, unchanged).

They arrived yesterday and work quite well (see other attached photos). I slid two cross bars to the right spacing so that I could essentially clamp each case securely using my clips. I was able to physically rock the car by pulling on the box handle without any indication that the box was slipping in the clips, so it feels very secure. While I am doing test drives/trips, I have a safety zip tie securing the handle to the rack just in case something goes wrong with the clips.

I've got some other ideas for things like molle panels which hang down from the rack over the rear windows that I need to start protoyping. If there is interest I'll keep posting as I move through these designs.

Cheers,
Ron

I am looking at the prospeed for my S. I would like to put a quick release RTT mount on it, but not sure they’ll fit. How much space is there on either side of center (approx 15” off center to either side) from the bottom of the rails to the roof? I’m looking at these- see link. https://solssentials.com/products/u...uXrwq0QfU_02WDSBWHvUaeKT32uarKril1XnvVsCc4TXl

I am traveling at the moment, but will get a measurement when I am back home in a couple of days.

I will say, there isn't much clearance, I'd guess around 3". Also keep in mind on the S (which I have), the rack extends back to the shark fin antenna, so if the idea is to slide the tent off the back of the car with these, the fin sticks up higher than the rack and that may be an issue.

Thanks for getting back to me. No worries. I think I only need about an inch and a half or 2 inches. I'm going to call the company that makes these and double check. The tent will still sit above the shark fin I believe. I think the shark fan only sticks up past the Bar like an inch or so and I will have about an inch and a half to 2 inches clearance between the bottom of the tent and the roof rack itself. It'll be tight but I'm trying to get the roof rack as low as possible.

So, the spacing is much closer than I thought. Along the center, clearance is no more than .75" between each cross bar and the glass, and is more generally around 0.5".

Out toward the edges, 2-3 inches in, there is about 1.5-1.75" of clearance from crossbar to glass.

Hope this helps!

Perfectly. Thanks.
