Video Transcript for Review of Thule Replacement Parts - Roof Box Hardware - TH05603

Ellen: Hey everybody. Ellen here at eTrailer.com. Today we're going to be taking a look at the replacement hardware kit for the Searsbox cargo box. This is a replacement hardware kit from Thule, and it's going to come with everything you see laid out on the table here.We'll get four of our larger plates. Four of our smaller plates. Four U-bolts with the threaded ends.

And then eight wingnuts. And also, a sheet of vinyl stickers.The vinyl stickers help to plug up any holes for unused mounting holes. So any kind of hole that you have in your cargo box that isn't being used, this can help to seal that up and prevent any leaks from happening. We'll get 15 of those little stickers. I'm going to set these off to the side, because my fan tends to blow them away.

But they do come with your kit.The more important part, though, will be our brackets. So everybody wants to know how big these are. Will they fit my cargo box And like I said, this does fit the Sears Box cargo box. But it does work for a lot of different cargo boxes out there. Especially if it has that style that has the U-bolts and clamps to get it attached.So this bigger plate here measures about 5 1/2" long by about 2 1/2" wide.

The mounting holes, center to center, for the two furthest ones are about four inches apart. Again, that's center to center. And then, the two . each one is separated by about two inches center to center.It is about 1/8" thick. Maybe even less than 1/8".

So it's a pretty thin material, but it is pretty durable. So this might flex around your bar, depending on how tight you get it. That can be a good thing, because then it'll help to kind of grip around and prevent any sliding, but, of course, you don't want to over-tighten, and then end up crushing this, or totally warping it.Our smaller bracket. Let's look at that one. From end to end, it kind of has these rounded edges. It's about five inches long. And about an inch wide. We'll have several mounting holes on this one. The two widest holes are four inches apart again, center to center. The two that are a little bit set in from that, center to center, those are three inches apart. And then from those narrowest holes to that center hole, is about 1 1/2" to our furthest out option is about two inches.So, two inches in between these two holes. 1 1/2" in between these two. And then it'll be the same going in the other direction. Now, those measurements are going to be the same for all of our brackets.Let's look at our U-bolt. So, from outside edge to outside edge, that U-bolt is about four inches wide. The threads are a little bit thicker. They go just past four inches. But I think four inches is going to be . excuse me. 4 1/4 inches. So, the center of the bolt to the center of the other one is a little bit wider than that at the ends, so they do kind of flare out. But at the top it's about four inches.There is a slight curve to that, so it'll work well for aero bars, elliptical bars, round bars. Pretty much most style roof racks. The tallest portion of that is just over two inches from the bottom of the threads to the very top of it. The inside area is about two inches. The threaded portion is a little over an inch. Maybe 1 1/8" long. So I hope that helps you in determining if this is going to fit for your box.Those handle nuts, overall, are about 1 1/2" long. The widest point, that little wing portion, is about 1 3/8". The nut, or the threaded portion inside, does sit back a little bit. Say that starts about where that bump is in the bolt, and that's about 3/8" deep. So I have a little bit of room.And then, it goes down about 7/8". So I just wanted to kind of go over those measurements with you to help figure out if this is going to fit your particular cargo box. This is going to be a very universal kit. A lot of boxes will have that four-inch-wide mounting holes.If yours doesn't but you still need this kit, you still need that clamp style, you can always drill out those holes. Just be careful whenever you do that. Always measure twice, cut once. And plug up any holes that you might have created on accide.tnAnd that's going to do it for our look at the replacement hardware kit for the Searsbox cargo box.

We ordered the replacement hardware kit for Searsbox cargo box. The video of the product at the internet site was helpful, but could have shown how to use the parts in an actual replacement. The kit arrived as advertised, as promised and on time. I would highly recommend etrailer.com 696708

First, I was amazed that I could find the necessary hardware to attach our Sears xcargo box to our car. Second, I was equally shocked that my order arrived so quickly. Awesome service. 474242

We used this cargo box for a 3000 mile road trip. Everything worked as it was designed. It is the perfect match for our Subaru Outback.

Awesome. The mount kit fit my Sears X-Cargo X-treme perfectly. Thanks! 683748

These would have worked fine if the Ubolt was 2 to 2 1/2" longer. I have the old Thule cross brace and the brackets of the brace require longer Ubolt threads height. I saved the package for my kids to use with their brackets. Had to use eye-bolt turnbuckle (because it was adjustable to fit the metal plates hole in the package) & 2 1/2" X1/4" carriage bolts. Install with the plates, turned out fine. I should have ordered the quick release package with the longer bolts. Lesson learn. Materials not wasted. Thank you 427326

I bought a Thule used and it did not have a number or name on it. The equipment to attach it did not fit my minivan or toyota highlander so I searched on etrailer.com for the right set. I measured the distance between all the existing holes on the Thule and found this set that matched up. Received it quickly, went directly out to the garage and installed them. I did have to gently tap two of the four with a mallet to get them just a smidge smaller, but they all fit now. Super happy with this purchase! I would recommend etrailer.com to anyone. Fits both a 2005 Kia Sedona and 2013 Toyota Highlander. Thule is an "Adventurer" of unknown year. 368217

I couldn't be more pleased with this product, which enabled me to very simply, easily, and inexpensively mount my wonderful 1991 Yakima Rocket box to my 2017 Acura MDX. With your product and by drilling 8 holes, the Rocket Box is securely mounted directly to the MDX. The challenge that your product solved is that the MDX comes with roof rails and crossbars, but the crossbars are fixed mount (don't slide), the existing holes in the box don't match the crossbar spacing, and the Acura crossbars are too wide for the Yakima U bolts. Various dealers tried to sell me expensive sliding tracks to mount to the box, mounts for the round Yakima crossbars to go on top of the Acura crossbars, a makeshift assortment of bolts/nuts/plates, and one even recommended I scrap my perfectly good 1991 Rocket Box and buy a new one. Your product simply and elegantly solved ALL of the problems in the time it took for ordering (great web site), quick delivery, and the 30 minutes it took me to measure and drill 8 holes. The quality of the product is fantastic and I can't thank you enough! Warmest regards and keep up the great work! 440754

Perfect fit for a used Sears Sport 20 Car Top Carrier that I had bought on F/B Marketplace! I liked the fact that this online retailer gave measurements on the widths of not of the carriage bolts (U-bolts), but also the brackets! That was and is VERY helpfulfor those who will be looking!.. 745030

I was worried about placing an order so close to Christmas time knowing UPS could potentially have issues delivering it on time. Since I placed the on-line order late in the afternoon, I was also worried that order might not get processed until the following day. I called immediately after placing the order. I can’t recall her name, but the person I spoke to said she saw my order and would follow it to make sure the item was shipped that day. It would have been too late if it shipped one day later as I was planning to leave on my trip. It shipped, and I received the item on time. I also liked having the ability to “see” where the package was at it travelled to me. Great work by all. Thank you. 733825

This replacement hardware kit was all I could have hoped for. I was able to attach my Sears Xcargo Sport 20 to my 2008 Ford Escape with no problems and in just over 40 minutes. I’m quite pleased with the price, the quick delivery, the quality of the parts, and the fact that they required no extra holes to be drilled or any adjustments. I’m ready to hit the road. 730988

    The replacement clips that will work for your old X-Cargo roof box are the Replacement Latch for SportRack Explorer Cargo Box # 03347. These may have a different look, but they do work with those old cargo boxes which you can see from the customer photos. I've also attached a photo to assist.

  • Can Yakima RocketBox Mount to 2016 Subaru Crosstrek With Factory Crossbars
    There is not a conversion kit available, but I reached out to Yakima in regards to attempting to mount this RocketBox, and they told me the following: "That is an older box but their (2016 Subaru Crosstrek) can carry it if the mounting holes are 4" apart. Have them measure the distance between the holes where the mounting hardware goes." What this means is that if your '16 Crosstrek has crossbars that are less than 4", which it should, then you should be able to use use this cargo box.

  • 1991 Yakima RocketBox Replacement Mounting Hardware Compatible with Aero Bars
    Your old Yakima RocketBox has mounting holes that are 4-1/2 inches on center, so there isn't a direct fit we carry. Instead I recommend using the Replacement Hardware Kit for Searsbox Cargo Box # TH05603. This will fit your Malone Aero bars like # MPG215 on your 2015 Toyota RAV4 as well as the factory bars on your 2008 Honda Pilot. I recommend using the gasket maker # LT37467 to seal the extra holes in your box to prevent water entry at the unused locations.

  • Replacement Mounting Hardware for Yakima RocketBox with 2 Inch on Center U-Bolts
    For your old rocket box, you most likely want the U-bolt Kit # TH05603 with the bolts measuring 4 inches center to center. There really isn't any specific replacement hardware for your older roof box with 2 inch by 2 inch u-bolts, but these are most likely the best option for your 2 inch by 2 inch desired fit to span an extra hole. You can drill holes if needed and fill any extra holes with # LT37467 to keep the box watertight.

    The Replacement Hardware Kit for Searsbox Cargo Box # TH05603 is most likely not what you need. Without knowing exactly what version of box, it is difficult to confirm a fit, but it is more likely the Replacement Mounting Hardware for X-Cargo Sport 20 SV Box consisting of: 4x Interior plates with 5 holes # TH03918 4x Reinforcing plates # TH10378 8x Carriage bolts # TH04852 8x Threaded knobs # TH04877 1 Sheet of vinyl hole covers # 10171

    The Replacement Mounting Hardware # TH05603 is 4 inches on center. If this is what your X-cargo XL 90040 roof box has, then it will be a fit without modification. Another option is the hardware kit # TH04997 that is also 4 inches on center. If your mounting holes are not 4 inches on center, you may need to consider drilling new holes. If this is the case, then I recommend using a sealant on your old holes like the Loctite RTV 598 High-Performance Silicone Gasket Maker - Black...

If this kit will not fit as-is then the remaining option is to drill some additional mounting holes to match the new hardware and seal up the old ones with a product such as JB Weld.

  • Replacement Mounting Hardware Kit for Sears Sport 15-CAV Rooftop Cargo Carrier
    The Sear cargo boxes were made for them by Thule. Although the original mounting kits are no longer available it is easy enough to adapt another u-bolt mounting kit to work well on this rooftop cargo box. It really just depends on the type of roof rack and the dimensions of that rack's two crossbars. The kit # TH05603 that you referenced includes u-bolts that fit bars up to 3-3/4-inches wide and 1-3/4-inches tall. If your roof bars are within these dimensions then this kit is the best...

  • Replacement Mounting Straps for the Karrite Road Rider Cargo Box
    I do have an option for you but there are no replacement parts available for the Karrite Road Rider Cargo Box due to its age. I am also not aware of any type of strap that will work in place of the original mounting straps. Therefore, the best option for you would be to remove the straps and then install the Replacement Hardware Kit part # TH05603 by drilling holes into the bottom of the cargo box to align the u-bolts.

These are no longer available due to the age of the box nor would they allow you to attach it to the roof rack on your Toyota Rav4. In order to do this however you can use the Replacement Hardware Kit part # TH05603 which will work just fine with the Karrite Road Rider Cargo Box.

  • Mounting Hardware for Older Sears X Cargo Box
    The best option for replacement mounting hardware for an old Sears X Cargo Box is going to be the Replacement Hardware Kit for Searsbox Cargo Box # TH05603. While it certainly is not going to be possible to verify a fitment of a cargo box that old, this hardware kit will still be usable, though you may need to drill new holes in the underside of the box to make sure the U-bolts fit through. You would then be able to use a sealant for the unused holes.
