Ellen: Hey everyone. I'm Ellen here at etrailer.com. Today, we're taking a look at the replacement mounting hardware for Car Top Cargo Roof Cargo Box.This is going to be that attachment hardware to get your roof cargo box secured to your roof rack on your vehicle. This can also work with several different older style roof cargo boxes out there, so I'm going to go over the measurements here to make sure that this is going to be a fit for your application.Basically, what comes in our kit, we'll get our four straps, or our four just flat brackets and then four of these . almost like a parentheses brackets shaped bracket. It's got that little notch there.
It'll work with several different bar styles, if it's round, square, elliptical, or anything else. And then we'll get our eight wing knobs or wing nuts to tighten those down. There are also four clips that come with it, just little spring safety clips.As far as the measurements go for our plates, the overall length for each of these is 5", going from that rounded end to rounded end. The distance between the mounting holes center to center is 4". The width is right at 1" and the thickness is about 1/8".
The diameter of those holes for each of our brackets is about 5/8", or excuse me, 5/16", maybe just under, or just about 1/4", which matches up, of course, with our U-bolts. The outside distance for each of these is going to be 4-1/4", so from outside edge to outside edge. The distance between these center to center, though, is going to be 4", which again matches up with our plate there. The diameter of those U-bolts is about 1/4". The length here on the side is about 1-3/4".
The overall height or depth, however you want to look at it, is about 2-1/2", going from the end of that little notch to the end of the threads. And then our wing knobs are about 1" tall and about 1-1/4" or 1-1/2" at the longest point.Now, this fits the Car Top model CTC-18S, but again, it does fit several other cargo boxes out there so it can be used for other applications. You just want to be sure that whenever you're tightening these, this hardware down on your roof, that you kind of go back and forth to make sure that everything's pulled down appropriately. You want to make sure that you kind of alternate each, from one to either side, so that you're not tightening one side more than the other.But that's basically going to do it for our look at the replacement mounting hardware for Car Top Cargo Roof Cargo Box.

This kit replaces the mounting hardware for your Car Top Cargo roof cargo box. Includes 4 U-bolts, 4 spacers, and 8 knobs.Great universal brackets for my Thule car topper! Thanks 693013
This was exactly what we needed. We received a cargo carrier from a neighbor but it did not have the brackets to attach it to the roof. These worked perfectly and were easy to use. 936319
This worked well for and older Thule ski box and a newer after market roof rack. The machining on one of the plates was off a few millimeters, but it was easy to tap it down without damaging the threads of the bolts. 936011
This hardware was the perfect solution to adapt my existing cargo box to fit my new OEM roof rack on my Honda Odyssey. The price was right and the shipping was blazing fast. Thank you! 932484
The replacement hardware for my Sport15-CAV luggage carrier was very secure on my roof bars (Rola Sport Series Roof Rack with GTX Mounting System for Naked Roofs, purchased from etrailer for a great price). I did move the rear bar back slightly to fit where the holes needed to be to fit the luggage carrier. To install the hardware, I used a 1/4" drill to make the holes. The V wrapped under the roof rack bars with the screws pointing upward through the roof carrier. The metal bars were inside of the carrier. I also want to mention that I was able to obtain a replacement key for my luggage carrier from eTrailer. It is wonderful to be able to use the luggage carrier again! 924647
Works great 882956
While I haven’t used the parts I ordered yet, I’m glad etrailer had parts available for me to be able to use an old Yakima Rocket Box. 882677
Worked well but just some basic instructions would have been helpful. Not super apparent how they go together and have no idea what the small clips were for. 867075

Product was as advertised...worked well. Package was shipped promptly and tracking information provided. 854319
Quick shipment. Perfect fit for my Thule Evolution Metallic 6410 Car Top Carrier. Looking forward to using it for my drive to the beach with the family. 853476
works! 852641
The video walkthru of this product was excellent. Product was an exact fit. 851681
Good quality. Way cheaper than Thule ha rdware 851043
Worked PERFECTLY for older off brand roof carrier. I bought a Reese Carry Power (still sold on Amazon and at Walmart) carrier at a second hand store for pennies. It came with no hardware. etrailer had a video that provided the specs and measurements for their hardware and it was close enough. Installed in less than 10 minutes and it is rock solid. Drove it around town for a couple of days in preparation for eight hour vacation drive and am 100% confident. Order was filled and shipped the next day and arrived in two days. Received email notices when order placed, filled and shipped. Highest satisfaction and rating available. Quality company and quality product. 845762
I had received an 18 cu ft hardshell rooftop carrier free but it had no hardware to attach it to the rails of my car. This kit contained everything needed for attachment and it fit perfectly. Enough stuff can be loaded in this that now we are able to see out of the back window of the SUV, handy with traveling yearly to and from Florida and Massachusetts, and the hardware kit holds it safely. 845077
These work really well...only wish they came with a rubber-coating on the parts that grip the rails on top of the car. Other than that it's a good product...stays in place without the bolts loosening at all. 824710
Quick service. Great. Now I can put my roof box back on the car with the proper parts. 818903
I’ll try to keep this one short. It has worked great for me. Secures my cargo box to my rails quickly and it’s also quick to remove. So much peace of mind compared to the old straps that the box had. 799493
Ordered this kit to attach an old X-Cargo carrier to the top of my Mazda CX-5. The kit worked perfectly for this application, and I was so happy that I didn't have to hunt for U-bolts and nuts from a hardware store. Two thumbs up! 704525
This kit worked great for my Sears X Cargo carrier for the 1992-2000 series. I also purchased the replacement keys which also was a perfect match for the cargo box. I purchased the factory made crossbars to mount this cargo box. 682793
We needed new hardware for our XCargo car-top carrier to take our daughter's stuff back to college later this month. Etrailer.com delivered the right parts in time. And etrailer's customer service was excellent. We're very pleased. 679158

I needed to attach a luggage carrier to the top of my vehicle more securely than just straps around it. After measuring the holes in the car top carrier I ordered this attachment. The pkg arrived on time and was reasonably priced for the strength it provided. While the “u” bracket wasn’t shaped like the rails (rails are flat rather that pointed), the bracket still fit on my 2013 Ford Edge rails. Car top carrier was secure. No whistling and other noise that the straps would have made was heard. I am a female, age 75. I will order from etrailer again. 672439
Soooo, we forgot we had our car-top carrier on when parking in a garage in Ybor City, FL. We stopped, pulled it off and in the process, lost a few pieces. When I Googled replacement parts, etrailer was one of the first to come up and they had exactly what we needed at a great price! Easy ordering, and quick delivery (I paid extra for 3 day shipping). No issues, very east website to navigate, will definitely use them again for anything we might need regarding our 28’ travel trailer! Thanks! 671637
