Most Popular Clamp On for 2021 GMC Acadia

We needed a better way to haul around 3 kayaks and after looking at a number of options, we settled on the Thule Stacker setup. Installation is simple and the stackers provide a sturdy option for hauling multiple kayaks. One of the best features is that they fold down when you don't need to use them. My shopping experience with etrailer was smooth and shipping was prompt.

My wife uses these to carry two small kayaks in the roof of her Subaru. They work great and we very happy with the purchase. She also likes finding her car easier in the parking lots, even with the carriers folded down.

The product seems great but I have not figured out how to get it safely attached to my bars. I have an Agricover Adarac on the bed of my truck and the crossbars are 1-1/2 x 1-1/2 inches square. I thought this would work well since it's for up to 3-1/2 x 1-11/16" crossbars, but it isn't secure on these. I'm going to try and figure out an alternate method for attachment though. Thule Hull-a-port Pro's are the perfect (mounting) solution but don't seem to be made any longer.

Great product and great customer service! Very easy to install, but I highly recommend to watch the installation video first. We used typical black office clips to clip the excess straps down since they came untangled when driving. Also, I recommend to purchase locks for the racks since we are concerned someone may steal them because they are so easy to take on and off.

've previously used the Yakima Kayak Stacker (old style), which worked fine but I always worried the straps would slip off the hook at the top while I was loading boats. They also didn't fold down, so had to be removed after use unless you wanted to look odd and cause a whistle while you drove down the road. They didn't have a universal attachment option, requiring adapters depending on the style and make of your crossbars. More recently I got the Thule "The Stacker", which is a superior solution. You thread the strap through a closed loop at the top, so you don't worry about straps slipping off while you're loading boats. They fold down after use and have a universal style attachment that fits around most styles and makes of crossbars. Good stuff. I really like the straps that come with these, as there is a rubber cover that slips over the metal cam buckle to protect your car's paint while you're tossing the strap over your boats to strap everything in. In order to shuttle our boats for river trips, we needed stackers to fit on both our cars, so it was time for another set. I had never heard of Rhino Rack before, but the lower price than Thile caught my eye, so I read about them and decided to give them a try. The Rhino Rack Nautical Stack used a closed loop at the top, which I liked better than the Yakima or Malone options, and came with the hardware necessary to install them into the C-channel of my Malone aero crossbars, which I wanted to try. I remember that with the Malone stacker, you had to buy the C-channel mount hardware separately. I really like the Rhino Rack Nautical Stack. They are a single post design, unlike the loop style of the Thule "The Stacker". I don't know if this cuts down on vortex drag, but it definitely saves you a couple horizontal inches up where the boats stack. The Rhino Rack Nautical Stack has textured rubber strips on either side of the post, which I believe is intended to cut down on vortex drag, but is also quite helpful in that boats tend to slip much less when you're just leaning them up against the post as you load up before you strap them. That's smart. The Rhino Rack Nautical Stack feels really solid. The mechanism for folding them down and locking them upright is easy to use and feels solid. Installation instructions were good. I tried to install into the C-channels without removing the rubber tubing in my Malone aero crossbars, but couldn't get the little squares to slide into the slots with the rubber tubing in place, so had to cut the tubing, slide the Nautical Stacks into place, then cut down some of the tubing I had removed and replace it in the remaining unfilled crossbar slot. That's not a knock on the Nautical Stack; just a tip in case you're trying to do the same kind of install I did. The one area in which I was less impressed was the tie-down straps that come with this kit. The metal cam buckles have no covering at all, so I'll probably still use my old Yakima and Thule straps instead and use these as backups. But overall, I think these are going to work at least as well, if not better, than the Thule option, and for quite a bit less money.

So much better than the 'C-shape' kayak holders. These things allow you to fit inside a garage, and add up to four kayaks. Very easy to use.

I can't lift my kayak onto my roof rack like I could when I was younger. This looked like a perfect answer to keep me actively using my kayak. It is simple to use, but it does take some strength as you have to lift your kayak onto the loader and must lift the kayak up onto the roof rack as it only loads to just before the top, so keep that in mind. The legs need to be about 6" - 8" longer as mine don't touch the ground at the connectors. I can only reach the ground with them lowered to where they are almost out of the holder. They also touch the Jeep, so I am going to have to carry something to fit between the loader and the Jeep to prevent scratching the door paint. I think if the legs were longer and they fit with both the holder/connectors then I think they might not touch the Jeep. I would have given 5 stars if the legs were long enough. It works with both my moulded J rack and my fold down J rack. It works with both style of kayaks, rounded and straight hulls.

About a year ago, I purchased one set of the Malone Downloader w/Lift Assist (MPG114MD-351XL) and second set of Downloader J-Style Folding Racks (MPG114MD) for use on a 2014 Subaru Outback with standard Subaru roof racks. I had no issue with installation and use of any of the parts using the enclosed instructions and online videos. Everything seems to fit properly and securely; no broken, unusable, or missing parts. Over the past year we've use the racks extensively for our 10.5 ft recreational kayaks on both short local trips and longer highway trips. We augmented the roof racks with T-handle hood and tailgate tie-downs and some locally purchased camlock tie-down cords. Everything working great with 10's of racking/unracking episodes. We've only used the Lift Assist maybe 1 of 10 trips when there's only a single person lifting, so can't provide as much feedback. However, the Lift Assist does work exactly as advertised and we're happy with the results. In addition, the friendly and well-informed folks at etrailer.com were a huge help with answering tech questions. Well done!

Arrived quickly and was very easy to assemble and attach to the roof of my Jeep. Now that I have the initial setup complete with the proper placement of the entire system, attaching and removing the kayaks will be a breeze. Will definitely make hauling our kayaks much easier and safer.

I think the Thule Hulaport kayak racks are the best, most secure way to transport your kayaks. I had these on my Xterra and hauled two kayaks up to Cape Bretton park in Nova Scotia, Canada from Connecticut, USA no problem. We were even able to store gear in the kayaks for the trip. I’m so excited to have them for my Crosstrek. Highly recommend these!

I installed these as soon as I got them and I’ve got to say, there are some extra holes for screws that are a tad misleading and the pieces that secure it to the cross bars don’t seem super secure. For reference, I do have Rhino Rack’s vortex crossbars so this should fit snug. The rubber tops were tough to get into place and I am worried they’ll snap when I go to remove my rack but Rhino Rack has yet to fail me with their products so I bet it’ll work out great!

This is a great product. As a novice kayaker I was nervous. The assembly was easy with clear instructions. My sales professional Crystal K. was a pleasure to work with. She knew the answers to all my questions. From placing the order to the delivery I am very satisfied. I will be using etrailer again. I can't wait to get my kayaks to the water.

I had the moulded downloader and needed the folding in order to fit in the garage. The top feed for the tie straps isn't as good as the moulded J-style rack, the strap came out of one, but the kayak stayed where it needed to be. It is easy to raise and lower the rack, but I am not always sure at what angle I am supposed to set them. With the moulded J-style, they are at the perfect angle for holding a kayak. I wish the clamp that goes under the bars were a better fit for the oval bars, but they do send two different size bolts and the longer ones work.

The Malone DownLoader is very good value for the money. The J-style cradle is nice when you have to muscle a kayak on top of a tall crossover or SUV. You can hook the edge of the cockpit onto the base of the cradle and flip the kayak up onto the metal hoop support. Carrier installation and removal is easy and doesn't require any tools. Materials are good, but not great and that's what prevents this product from getting 5 stars IMO. The foam padding is nice enough and has been durable, but the metal plate that attaches the carrier to the roof rails is plastic coated steel and the plastic cracks over time, and leads to rust on the steel plate beneath. Not a big deal, but it might compromise the plate over time. I also wish that the provided nylon straps were longer, and that the ratchet buckles were covered in rubber to protect the roof of the vehicle and the windshield when you're trying to get them around the hull of the boat. We quickly replaced these with longer aftermarket straps that have rubber covers over the buckles. Those minor points aside, the Malone DownLoader kayak carrier gets the job done easily and safely, and does so at a very affordable price point.

Bought a pair of these to go on 59" rhino rack bars on our Outback Wilderness and am really pleased. I left the bars full width - they are not a head banger on the car - and mounted the Hullavators as far outboard as possible which means the kayaks clear the side of the car and wing mirrors without folding them in. I did have to modify one Hullavator to make the Hobie Lynx fit (36" wide Lynx = 36" max Hullavator width)

The Hullivator was for my wife to give her the option of loading and unloading by herself. It couldn’t be better. She now goes kayaking anytime she wants with little effort and no need for me to help her. Excellent product that’s worth every cent. Was super easy to install too.

Needed a rack to haul my kayaks on my jeep patriot and this price was unbeatable. Works well, though I did not like using the foam blocks. Good first rack for new kayakers.

We needed a carrier solution that folded down easily because of our garage door height. The Malone Pro2 Kayak Carrier has performed flawlessly over the past year. The kayaks remain stable and never shift even at freeway speeds. The foam blocks fit our crossbar well and offered a rattle free ride, which is nice. The one drawback to this system is how difficult it can be to actually route the straps. Without a ladder, it can be nearly impossible to get the strap over the kayak and hooked into the carrier properly. After you find a system that works for you, it becomes easier but I still think that the stationary carriers are more user friendly in that regard.

First experience with purchasing from etrailer. Absolutely felt that my order was personalized which is a nice touch. The Rhino Rack S512 folding JStyle Kayak holders arrived boxed impeccably with no damage whatsoever and the price was great! Fantastic first time experience. Looking forward to using them. Thank you.

Received crossbars when promised. Installation was straightforward. Was missing a couple parts. Informed company and they responded quickly with replacement parts. Very pleased.

Product was as advertised, however it was missing four bolts that I had to get at a hardware store, but other than that it was fine. Service from etrailer team was outstanding.

I've been using the product for two summers now and it is perfect for what I'm using it for. My canoe is an Old Town Discovery 133, it's very wide and I initially had trouble fitting it in the brackets with how relatively narrow my Rav4 is, but the instructions that came with them mentioned I could just flip them around. That worked perfectly. I only use the brackets and the tie down straps from the kit to tie the boat to the crossbars, and then use the painter lines I put on the bow and stern of the boat to tie those to the car. That rides on the highway very easily with no shifting. With two people, the load/unload time is around 10 minutes as long as one person knows what they are doing. This kit had exactly what I was looking for, seems built to last, and if I ever need another kit to help tie a canoe to a car then I know I can trust this product to get the job done safely and reliably.

I acquired a second kayak and needed a system to fit the factory racks on my 2011 Toyota RAV4. Etrailer.com has always had information on what fits and has always had the item needed for the job. I attached the Yakima BigStack to the top with ease, and, with one other person to hold the kayaks while I secured, tied two of them down for a long road trip to Northern Minnesota. The system worked just fine. The only caveat was in the configuration of multiple boats in the instructions. The diagram has two boats on the same side of the posts, however, I found it more secure to put one on either side ( other reviews of this product on different Internet sites have found similar results.) The boats made it through the trip with no shifting.

Worked great on our Subaru Crosstrek with factory crossbars. Loading very easy, and it was very secure, for our 2 kayaks. The Yakima Big Sticks are easy to install/setup and take off. Very happy with our investment,

These work great and I was able to install them on the OEM rack for my truck. The only downside is that the threads for the clamp hang down a little too close to the roof for comfort.

The Rhino-Rack 2 Kayak Carrier I ordered from etrailer was easily reviewed and ordered from their website and ALL communication relative to order confirmation and extreme detail included in their tracking was nothing short of phenomenal! The items were packaged with care and arrived intact. These fit our basic Lexus crossbars and is the perfect product for carrying our two (2) kayaks. My hat goes off to the great folks at etrailer -- It doesn't get any better than this!!!

Brought home a new kayak yesterday using this J cradle for the first time. Easy to set up and load. Two complaints: not impressed with the strap buckles - had to tie knots to secure. And the 3-inch bolts weren’t long enough to easily attach the cradle to my Rhino Rack crossbars, so I had to replace them. Also got my finger pinched pretty good adjusting the cradle knobs - my fault for not being more careful, but just saying …

Great product for the price - The cradles were very easy to mount (and lay flat once folded). The videos were helpful in showing how to set the straps in the most efficient way. I test-drove my car today with my fishing kayak on top on a 80-mile round trip (a mix of freeway, country road and dirt tracks). The kayak was perfectly still, no particular wind noise and I was able to muscle to kayak up the roof and take it down on my own (it's a 52 lbs boat). I really recommend that product and I'm glad I went for J-Style cradles!

The keys are an issue (wish they were metal), but everything else is great! I go sunrise kayaking only and hate putting straps on with cold hands at 3:30 in the morning. I have a Nissan Pathfinder and was able to put this on with another set of Malone J-hooks so that I can have a second kayak when I go with someone. Once the fear subsides of it possibly falling off, you realize how quick and easy this thing is to use. It takes me 1 minute instead of 9-18 minutes to get my kayak up and secure. I have tested it at 75mph without any jiggling or issues. I sat on this in my shopping cart forever and finally pulled the trigger. If you kayak at least 10 times a year or are going at high speeds for extended periods of time in warm weather, totally worth it. If not, well, there are cheaper options out there.

Rec'd earlier this week, so today i will install. The item was obviously a return. The logos are nearly scratched off in places, all the items were loosely thrown in the box, and the 10mm wrench and hex key were missing. i think everything else is there. The keys should be a bright color instead of black, some spray paint will fix that. Anyhoo, i am a little disappointed.

Well made, decent price, free and fast delivery. My only complaint is about how awkward it is to get the straps up and over the kayak. But that is true of most carriers of this design.

Good quality materials and easy to install - and uninstall. Two changes would give this product 5 stars: Some type of strap holder at the top of the back rack would make it easier to strap down the kayaks and some type of security lock so someone doesn't borrow your new racks while you are out kayaking. One unique thing to remember for the 2017 Toyota RAV4: the back OEM cross bar is about 3" shorter than the front cross bar - this takes some adjustments for the placement of the racks to fit 2 kayaks and still open the rear hatch.

Wry disappointed in such an expensive rack and kayak carrier. It is extremely difficult to reach the carrier to place two kayaks. We are very uncomfortable transporting the kayaks for longer and highway travel. I would not recommend these to others. We likely will purchase something other in the future. I’d rather put the kayak in a car or pickup truck that they would fit in.

We bought this Kayak rack for my mom to put on her 2016 Jeep Grand Cherokee so her and my dad could haul their kayaks easier. The mounting hardware was a little tricky at first but once we figured it out, it wasn't bad at all. It holds the kayaks in place nicely. Had no issues with them getting loose or moving around. Seems to be built well and they're very happy with it so far.

I am happy with my purchase of the Malone SeaWing with the load assist feature. I use it a lot and it is holding up well. I have square crossbars, and the wing base can be flipped over during assembly to fit square bars perfectly. The load assist really does make it easy to get my 14 and 16 foot kayaks on the car by myself. Another reviewer stated that the load assist feature put black streaks on his thermoformed kayak, and I had the same experience. I fixed that by wrapping heavy duty, double sided Velcro around the areas of contact, and that has worked fine. They are still in place one year later. Four stars because Malone should have covered the load assist sliders in a non-marking material.

The lift assist would not work with a skin on frame kayak. Repeated use would damage the skin. You can see in the pic that the load assist pushes in on the skin, and would not slide all the way into the storage position without lots of pressure on the kayak. Etrailer would not take retuttome inern since I installed the rack, but there was no way to know without trying. So bottom line - don't try to use this on a skin on frame kayak. And don't count on etrailer for returns when they sell a product that doesn't work as advertised.

Wow is all I can say. I put the Malone cross bars on and then this went up in less than an hour. For an older very petite woman, It went up very easy. Yes, be aware shorties: you need a step stool to be able to get the rack up. I have a folding one that will go in my car. Yep so glad I did this. Thank you Paul B for the help in getting exactly what I needed.

Super easy to install, quality built, rock solid paring with crossbars. Zero doubt about safety. Could not ask for a better product. Worth every penny. And they fit perfectly with the Malone crossbars for my 2019 Equinox. Customer Service via chat helped me find the one and only pair that would fit those crossbars. So glad I found etrailer.

I'm writing this review after one year of ownership. I bought two sets of these J-hooks alongside a Malone Airflow 2 roof rack for our 2009 Subaru Forester. I use them to haul a 10ft and 12ft kayak simultaneously. They've done an excellent job and have held up on both short 20-minute drives to local lakes as well as on 10-hour road trips. I'm very satisfied with the combination of the rack and these carries. My only complaint is that you also need to buy the "Aero Style Crossbar T-Slot Fit Kit for Malone Kayak Carriers" pack separately for each set of J-hooks. This part allows you to more securely fasten the hooks to your roof rack. I wouldn't have been comfortable taking kayaks on a road trip using the J-Pro2s without this extra ability to secure them down. I wish the two items came together instead of having to buy them separately. That said, they do the job exceptionally well, so it's not a dealbreaker in my eyes.
