Yes, if you:

  • Park your car in a garage and would rather just fold down the rack instead of taking it off every time

No, if you:

  • Have a roof rack with square bars and don't want to get an adapter to make this fit
  • Leave the rack on your roof while you’re out paddling and worry about it getting snatched

This J-style kayak carrier allows you to transport 1 kayak safely and securely on your roof rack. The space-saving cradle system mounts to most crossbar styles and folds down for storage. Expandable to carry 2 kayaks. Includes tie-down straps.


We purchased two sets of the Rhino Rack J Style Kayak Carrier since we have two kayaks. They work great and were easy to install. We were particularly impressed with the quality of the tie down straps. We bought them a year ago and used them quite a bit since then with no problems.


These racks are so great! The option to fold them down means I can leave them on the car for a few days between kayak trips. They’re very sturdy and we love that they come with the tie down straps, but I wish the hood/trunk anchors were included. Just another order I guess!


I bought these folding-J racks to accommodate two kayaks on my ‘15 Honda Accord. I mount the sit-on upside down on the Rhino Rack roof rack and the touring sit-in on the folding J-racks. With it having folding capability, I’m able to set at proper angle to accommodate both yaks. When traveling home with the new sit-in, I had to pull over on the side of highway to re-tighten the straps since a strong side wind caused it to move. I over tightened because that caused indentation on the bottom of the yak from the cross bars. That was remedied by putting in the sun and they pulled out, per seller’s advice. Yeah, freaked me out a bit being my first yak! I use bonnet straps on the ends now, too. Lesson learned. The folding J-rack prevents any possibility of indentation on the bottom of the sit-in yak. These folding J-racks are well made and I recommend them.


Excellent product only issue is that it is very heavy. I’m using it on Yakima bars with a skybox. Yakima says load limit just over 110lbs on my Toyota Camry. So that doesn’t leave much room for cargo after loading camp stuff after. A double sea kayak or two singles.


Sturdy cradle and easy to install. Difficult to keep tie down strap looped over top of "U" bar while trying to get it over the kayak, keeps slipping down. We made a channel out of foam to keep the strap in place and now it is easy.

These mounts are great! I bought two of them to mount on the Rhino-Rack RS 2500 Roof Rack for Naked Roofs - Vortex Aero Crossbars (RRRS118B) along with one set of Anchor Straps (RRRBAS-2). I really like that the angle is adjustable with markers to be consistent. It makes mounting your paddle on the upright bars before placing the kayak a piece of cake. I dont normally leave them on if not in use because it wouldn't take much to steal them and the added drag isn't necessary. I considered only getting one and buying the extension piece (RRS512X). However, I was concerned about where I would put the second paddle and having the ability to mount 2 kayaks at angles less than vertical seemed like a bonus. Considering the small price difference it was worth it to me to get two. The straps that come with are more than sufficient for any car and probably most trucks. The blue ones are a bit long for my application. I had an issue keeping the excess length contained on the freeway, probably going to cut them. All together, these mounts are very sturdy and give a great deal of confidence even with a crosswind on the freeway. Note on the photos: I have a hitch on my car with chain loops so I only needed the anchors for the front.


Product is as it says it is. Fast, free shipping from too! Haven't had chance yet to take the kayaks on a trip yet but don't expect any problem as these are meant for wide and heavy kayaks. Also before i forget, did answer my question before purchase online...basically confirming they'd hold my wide fishing kayaks and its max weight limit of 99lbs.

I've attached pictures to show my setup...sweet looking with two pair of these J-Carriers, my Yakima rack and roll 78 trailer plus the Thule Medium Sonic Carrier in between the J-Carriers. Looks nice!


Purchased these alongside a Rhino Rack roof rack system and love them. The paddle holders are great, and I enjoy how these fold up and down and can be calibrated to the width of the vehicle. These feel very sturdy. I recommend Rhino Rack!


Carrying kayaks with these J racks (I bought 2 carrier sets). They fit on well and were sturdy once they were attached. The adjustable / folding style is great also.


Using these as an additional support for the kayak/ motorcycle trailer!
Well built and should work out well!


Does what I needed it to do: carry my kayaks on my car! Website is great for installation information, too.

I liked it very easy to install. I appreciate the attention and I will definitely recommend my friends. Thank you very much


I've mounted both the Rhino-Rack RS 2500 Roof Rack and these S512 J-style Folding Kayak Carriers that I purchased from etrailer. Everything was easy to install, fits well, looks and works great! I am extremely happy with the products, the deliveries and the customer service rep was friendly and helpful when I had a question about the fit of the kayak carriers. I own a 2009 Honda Ridgeline and the carrier rack looks great with very little wind noise while driving. I'm taking the kayak out for a trip tomorrow morning.


As usual...etrailer shipped out order immediately...we received it in mint condition...and it is mounted to the roof rack on our Jeep. My wife and I recently purchased some sea kayaks...and the Rhino Rack is an awesome carrier. The ability to drop the rack flat when not hauling boats...and the ability to add on additional components to carry more boats is a winning design. The kit comes with a very well made set of straps to secure your craft securely. The rack even secures your paddles if you have one piece...or just don't want to take up room inside the vehicle to store them. Well thought out appears to be very well built. Additional kits are available to adapt to specialty crossbars if that is what you need.

We are still loving the Rhino-Rack J-Style...recently purchased a Rhino-Rack Universal Load Assist Side Loading. It makes loading 17ft Sea Kayaks on our Jeeps roof rack a piece of cake.

This is an excellent product. Easy installation, fits wide load bars. Folding mechanism works easily and is very secure. Tie-down straps provided are top quality.

One year later, I still love the product. It has gotten plenty of use and it has held up very well.
Brian - 06/21/2021


The Rhino Rack is excellent. Solid and sturdy and comes with quality ropes and tie downs and clips that won't ruin your car during tie down. A great buy that will last and will keep the driver without worries.


I researched a ton to figure out which racks would be the best for our two kayaks and came upon these Rhino Racks. Much better value than the top brand (you know which one). And these are from a company that stands behind their product. There's also cheaper no-name ones on auction sites, but do you really want to trust your expensive yaks to a no-name company? I've had these for a year now and they really hold up well and secure my kayaks. Plus that added oar holder is super nice. I've even gotten compliments on them. Would buy again. Recommended!


The rhino kayak carrier is super easy to install. It is made very well. It is sturdy and love the paddle holder.


Very easy to install on my Rhino rack cross bars. Easy to adjust cradle angle. Kayaks fit nicely. Also purchased extension bar for second kayak.


Thank you. The Rhino is assembled and in place and carrying my beautiful brand new kayak. I am very satisfied with this purchase and was able to easily follow the instructions.


Pros of this rack are it can handle 99 pound boats, has a variety of angles you can set it at, and it has a paddle holder. Straps it came with are very high quality. 4 total straps, which was great.

My only complaint is with no slot for the lashes to sit in, they do move and slide down before you tighten them. I have a higher SUV so this is annoying, but I fixed it with two pieces of foam and some gorilla tape so the tie down stays put. On a car or lower SUV it wouldn't be an issue.


These are the best. They fold when not in use. They carry my 13 ft Wilderness Kayak like a baby. I am happy.


Easy to install. Used it the day it arrived. I love how easily it adjusts and folds down. It looks sturdy and durable. The straps are heavy duty and easy to use. I especially like how the strap ratchets are coated in rubber to reduce scratching or denting the kayak and car.


Fits very well and easy to install.


It’s very sturdy and easy to use. However, I’m concerned as it could be stolen easily.

This item # Y04073
Yakima JayLow Kayak Carrier w/ Tie-Downs - J-Style or Post Style - Folding - 1 or 2 Kayaks
fits elliptical crossbars and you can purchase the locks separately at item # Y07202
Yakima Same Key System (SKS) Lock Cores (QTY 2)
but one thing to keep in mind is that you will need a minimum crossbar spread of 24 inches.
