Review: Perfect Roof Rack and Cargo Carrier for Mazda 3 - For this year's summer fun I wanted to go further in our adventures with my little 2013 Mazda 3. Did a lot of research on compatibility, price comparison, and other reviews. Then went for the ROLA Roof Rack with the Curt Cargo Carrier. A perfect combination! The ROLA Roof Rack - There are many choices for universal roof racks that are appealing and affordable. BUT they will either damage the paint at the point of contact OR damage the weather stripping at the door. Sure, you could save a couple hundred if your fine seeing 4 scuff marks or worse on your roof everyday or if you don't mind raindrops tapping your shoulder and pooling on your leather seats. Luckily the Mazda engineers had the foresight to include anchor points on this model. There were only a few roof racks to choose from that are compatible with my Mazda 3 and they were double or triple the cost of the universal racks. I decided on the "ROLA 59833 Removable Anchor Point Xtreme AP-GTX Series Roof Rack for Mazda 3 Hatchback". The reviews were great and I didn't have to pay extra to thule around town and yakima'bout having a label. Easy to install (about 20 min). The black compliments the trim. And now my sporty little Mazda 3 is adventurous like those pristine Subarus that only see dirt when taking their labradoodle to the dog park. The Curt Cargo Carrier - This one was much more difficult to select. Do I go with an open basket or a closed bag or a hard shell? Then there was the issue of spacing (between bars and connection points) and orientation (having front/back instead of along the sides). And of course spending more on the roof rack meant I had less for a carrier. I opted for the "CURT 18115 Roof Rack Rooftop Cargo Carrier 41-1/2" x 37" x 4" Mounted". An excellent decision as I wasn't limited to what a case can carry and didn't need to worry about a ripped soft case or broken zipper. Plus this cargo carrier is adjustable in it can fit on a wide range of roof racks and can be expanded with an extra accessory. Easy to setup by myself in minutes. Sturdy construction. And just looks cool. The protruding thread from the connection points aren't a problem if you can load items between them like camping chairs, sleep pads, etc. The distance between the connection points and the bars on my Mazda 3 is offset by maybe half an inch but it's ok with this cargo carrier. The carrier has these wide "feet" that can attach to any set of bars on the basket to accommodate different roof rack separations. And because the feet are wide there's some leeway if you need a little more or less distance. Get a cargo net and extra bungee cords and you're good to go. So give your beloved Mazda 3 a new personality and go exploring! Review: Damaged goods: Problem Solved - My rack came in damaged. It appeared to have been an open box deal as the box appeared retaped and some of the items were opened and rattling around inside. The box was damaged and two mounting pieces were broken. Don't get me wrong, I love open box deals and I almost always go for the Warehouse deals. What I was upset with was the fact that I paid full price for a damaged product. I called desertcart CS and they offered me a replacement. Like I said, I like open box deals and shipping this thing back would have been a nightmare due to the damaged box. When I explained that, they offered a partial refund instead which I was more than happy with. Now, the product itself. The rack seems solid and well made. The fairings aren't plastic like I thought and they actually seem pretty well designed. The brackets that hold the fairing on the other hand... I am going to need to replace two of them... Snappy plastic that likes to break on installation. The size is good, perfect for my needs. I still have room on the top of my Outback to mount my radio antenna. Installation was relatively easy, instructions pretty straightforward. It would have between easier with two people. I.am going to replace the wing nuts that secure the basket to the roof with standard nuts. The wing nuts are exhausting to use on my roof as they require a ton of effort to use on thinner bars. I also plan on sealing the joints and replacing bolts with steel ones to minimize future rust. On of the other top reviews details how to do this, so I won't repeat it here. One of the Allen nuts was improperly cast, it had no head. Easy to replace, but shoddy manufacturing. I will update this if I ever have issues in the future, otherwise you can presume it's still a 5 star! First impressions: 3 star Satisfaction with customer support: 5 star Hardware quality: 3.5 Cost for value: 5 The overall reason that this gets a 5 star is that, despite lack-luster manufacturing and cheaper parts, it still has a great value for the price. The cost of upgrading parts to make this a truly nice piece of hardware is minimal, but it will take effort. If I disliked that kind of thing it might get a 3 or 4 star, but I can't do that as, to me, it is not a 3 star item ## Features - ENHANCED SECURITY. This rooftop cargo carrier has 4-inch high walls to keep items securely in place. It also features a windshield on the front to protect cargo from high-speed winds during travel - EASY TO USE. Adding cargo space to your vehicle is easy with this rooftop cargo carrier. It frees up the inside of your vehicle for other cargo or passengers. It can also accept a cargo net or cargo bag for increased item security - UNIVERSAL FIT. This rooftop cargo carrier securely attaches to most roof rack rails, using simple, universal brackets. The roof basket comes in two pieces and assembles quickly with the included hardware - DURABLE BUILD. This roof rack basket is constructed from tubular steel to promote high strength and a lightweight design. It is also finished with an E-coat and carbide black powder coat for long-lasting corrosion resistance - EXPANDABLE. Great as a car roof rack, this cargo carrier is expandable. With the separate extension piece CURT #18117, the usable square footage goes from 11 sq. ft. to nearly 17 sq. ft ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004O844DS | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #1,450,716 in Automotive ( See Top 100 in Automotive ) #2,252 in Cargo Racks | | Brand | CURT | | Brand Name | CURT | | Color | Black | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.4 out of 5 stars 2,168 Reviews | | Global Trade Identification Number | 00612314181155 | | Included Components | Roof Cargo Carrier | | Is Foldable | No | | Item Dimensions | 41.5 x 37 x 4 inches | | Item Type Name | Rooftop Cargo Carrier | | Item Weight | 29.1 Pounds | | Item dimensions L x W x H | 41.5 x 37 x 4 inches | | Load Capacity | 17 kg | | Manufacturer | Curt Manufacturing | | Manufacturer Part Number | 18115 | | Manufacturer Warranty Description | One Year Limited | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Number | 18115 | | Mounting Type | Easy Snap | | OEM Equivalent Part Number | 18115 | | UPC | 612314181155 | | Unit Count | 1.0 Count | | Vehicle Service Type | Car | ## Product Details - **Color:** Black - **Brand:** CURT - **Item dimensions L x W x H:** 41.5 x 37 x 4 inches - **Load Capacity:** 17 kg - **Mounting Type:** Easy Snap - **OEM Part Number:** 18115 - **Global Trade Identification Number:** 00612314181155 - **Automotive Fit Type:** Universal Fit - **Manufacturer:** Curt Manufacturing - **UPC:** 612314181155 ## Images ![CURT 18115 Universal 42 x 37-Inch Black Steel Roof Rack Rooftop Cargo Carrier - Image 1](https://m.media-amazon.com/images/I/71UpL-6u3aL.jpg) ![CURT 18115 Universal 42 x 37-Inch Black Steel Roof Rack Rooftop Cargo Carrier - Image 2](https://m.media-amazon.com/images/I/71MHx69890L.jpg) ![CURT 18115 Universal 42 x 37-Inch Black Steel Roof Rack Rooftop Cargo Carrier - Image 3](https://m.media-amazon.com/images/I/718W0UG9kSL.jpg) ![CURT 18115 Universal 42 x 37-Inch Black Steel Roof Rack Rooftop Cargo Carrier - Image 4](https://m.media-amazon.com/images/I/91y5q0iRnnL.jpg) ![CURT 18115 Universal 42 x 37-Inch Black Steel Roof Rack Rooftop Cargo Carrier - Image 5](https://m.media-amazon.com/images/I/81+VzNjXmwL.jpg) ## Questions & Answers **Q: The crossbar spacing for my car's roof rack is 30 inches....will this Curt unit fit properly?** A: The pads are not fully adjustable or is it a universal fit. Will not fit a 2021 GMC Terrain (with or without the extension). **Q: what are the interior deminsions without the extension? i just want it to hold an off road tire (33's)** A: just measured. interior dimension: 37in side to side, and 36 in from front to back at top and 40 in from front to back at the bottom. **Q: What is the maximum load of this product?** A: I own the basic 18115 and have one with the extra extension added. Both with hold more than the factory cross bars on an escalade. I have had up to 200 lbs and had no issues **Q: Does this come with mounting brackets? If so, would it be wide enough to look good on the roof of my 2010 f150? Planning on doing dual light bars** A: I think it's too long for a 2 door truck. It will be wide enough though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Roof Rack and Cargo Carrier for Mazda 3 *by J***K on July 3, 2019* For this year's summer fun I wanted to go further in our adventures with my little 2013 Mazda 3.

I own an Isuzu VehiCROSS, and I wanted a roof basket that wouldn't look out of place on it. Most baskets are too boxy or angular; I wanted something with some curve to it. I also wanted good quality. The Curt 18115 roof basket fit all of those needs. While inexpensive and light weight, once put together it is very solid. After I installed it, I could grab it and rock the whole car and it didn't budge an inch. I feel that it could easily carry whatever you put on it for your adventures. Assembly was very easy, a few screws torqued down with a small allen wrench (which Curt helpfully supplies) was all that was needed, and it was ready to go on the roof. It was easy to install by myself, but some people may want to have a helper around (especially if you have a lifted vehicle). Once in place, it was just a matter of locating the plastic supports and u-bolts in the right spots, centering it up, and torquing down the supplied knobs. At that point, it was done. The hardest part was getting the thing centered! Are there any negatives? A few. All of them are minor, and can be easily and cheaply fixed with a little effort. First, when installing the front wind fairing, take care with the plastic brackets that hold it on to the basket. I put my basket together on a cold day, and when I was tightening up the screws for the brackets, the bracket cracked. Fortunately, Curt Mfg. sent me replacement parts when I emailed them, but if you have the option, put it together on a warm day, or put the brackets into some hot water for 5-10 minutes to make them a bit more flexible. I did that with the replacement, and it worked great. The u-bolts have a fine-pitched thread; tightening the knobs down to get the basket solid on the bars took a great deal of time and effort. After the bolts were snugged down, you may also be left with an inch or more of the bolt ends remaining, which can snag on things you put inside the basket. If this is the case for you, keep reading! Lastly: Rust. Since the rack is steel, and uses steel bolts and nuts, water can get into the seams of the tubes that slide together and quickly forms rust. Mine rusted fairly quickly after a heavy rain; a bit of water got inside the tubes, and led to rust, because the inside of the tubes aren't powder coated. So in lieu of these issues, I decided to take matters into my own hands. This is also why I gave the product fewer than 5 stars. Fortunately, in the Amazon reviews for the Curt 18117 extension, another user gives a good set of tips on what parts to buy and how to prep things, which I'll reproduce here. These notes are slightly different. You don't have to follow them exactly (with the exception of the nut and bolt sizes); if you want to mod things another way, go for it! 1. First, off any existing rust with a rag or other means, before it becomes a real problem. After cleaning, use some grease or spray oil/penetrant. Apply it to the problem surfaces of the tubes, such as where the tubes slide together, and on the insides of the tubes. I sprayed a generous amount of Liquid Wrench silicone spray inside mine. 2. Fit the tubes together, then use a dollop of black silicone sealant at each joint; smear it around and work it into the seam. Then put another dab on each screw hole on the top and bottom tubes. 3. Replace all fasteners with stainless steel screws and nuts: 15 pcs - M6-1.0 Stainless Steel Nylock Nut - Fastenal #1L2550000A40000 ($0.43 ea) 8 pcs - M6-1.0 Stainless Steel Acorn Nut - Fastenal #11508471 ($0.27 ea) 5 pcs - M6-1.0 x 16mm Stainless Steel SHCS - Fastenal #MS2550016A40000 ($0.48 ea) 3 pcs - M6-1.0 x 40mm Stainless Steel SHCS - Fastenal #MS2550040A40000 ($0.84 ea) 3 pcs - M6-1.0 x 25mm Stainless Steel SHCS - Fastenal #MS2550025A40000 ($0.64 ea) As you can see, these parts will only cost a few extra dollars. They are worth the peace of mind. Note that you will need a different size allen wrench, as the one supplied by Curt will be too small for these screws. 4. Once you have the screws in place, take a break and let it dry for 24 hours. 5. Once the sealant has cured, use more sealant on any other spots which may collect water and rust; you basically want to seal up every hole you can on the rack using the sealant. Let the sealant dry for another 24 hours. 6. After this last round of sealant, you may then want to give the rack another protective coat; use whatever you think is best for your application and aesthetic desires. For myself, I am planning on using black PlastiDip. I purchased 3 cans of the stuff, plus a spray handle. I should be able to apply 2 or 3 coats. After you have the rack completed, you can mount it on your vehicle. I also intend to put pieces of rubber hose over the u-bolts, to give the roof bars a bit of additional protection. Also, I am going to replace the knobs with additional nylock nuts. If you do this, use an extended length 10mm socket to drive the nuts on. The extra length of the socket will allow for the extra bit of the u-bolt to pass (if that is an issue for you like it was for me). Afterwards, you can take a rotary tool and cut off the end of the bolt, leaving about 1/4 to 5/16 of an inch exposed. Then put one of the M6 acorn nuts over the end (you can add a touch of low or medium-strength thread-locker compound to the bolt as well). That should complete the install, and there shouldn't be any further issues with rust. Note that if you intend to add the basket extension (Curt #18117), you will need four additional 16mm screws. I really suggest getting the extension if you have the room for it. You will need about 30 inches between your roof rails for it, otherwise it won't be very stable on your roof. Hopefully my pictures illustrate what I discussed above. I intend to update this review as I complete the project. ## Frequently Bought Together - CURT 18115 Universal 42 x 37-Inch Black Steel Roof Rack Rooftop Cargo Carrier - CURT 18201 65 x 38-Inch Elastic Cargo Net with Hooks for Roof Basket --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/1237200-curt-18115-universal-42-x-37-inch-black-steel-roof](https://www.desertcart.com.ar/products/1237200-curt-18115-universal-42-x-37-inch-black-steel-roof) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-21*
