The Lockrack watersport carrier with adjustable base lets you transport 1 kayak or canoe or 2 stand-up paddle boards on your roof rack crossbars without the need for load straps. The rubber-coated arms can be adjusted to the width of your boat or boards and ratchet into place for a secure hold. Once they are set, the arms lock into place and can only be removed with the included keys, ensuring your gear is safe and secure. Because a single person can quickly and easily load the boat or boards onto the carrier, and since load straps aren't necessary, you'll spend less time loading and unloading your gear and more time out on the water.

Quick, Strapless Loading with Ratcheting Arms

Loading a kayak, canoe, or SUPs onto the carrier is easy for one person to do. With the inner arms already installed and the base set to the width of your boat or boards, simply stack your gear on the carrier's base, making sure they're pressed against the arms. Then just insert the outer arms into the carrier and ratchet them down so they're sitting snuggly against your gear. Once fully locked around your gear, the ratcheting arms' curved design creates a lateral and downward force, ensuring your boat or boards are secure and won't slide around. And because of this design, you don't have to use load straps to secure the boards to your roof.

To ensure your boat or boards aren't damaged during transport, the ratcheting arms are covered with a rubberized sleeve. This rubber-coating flexes against the sides of your gear to protect them from scuffs and scratches, while still providing a secure hold.

For longer gear and longer trips, we recommend using bow/stern tie-down straps (sold separately). Because the carrier holds your gear in the center, the bow and stern can be subjected to damage caused by high winds. The bow/stern tie-downs provide additional support to help protect against this type of damage.


When not transporting your gear, the carrier's arms can be secured flat against your crossbars. In this position, the carrier adds less than 2" of overhead height to your roof rack crossbars. This means you won't have to remove them when pulling into your garage.

Integrated Locking System

Four locking points secure the ratcheting arms and your gear to the carrier. When you ratchet the arms down, they lock in place and can only be removed with the included keys, giving you peace of mind when you're away from your vehicle and gear. For added convenience, the keys hook onto your key ring.

Easy Installation with Universal Mounting Hardware


The rack installs quickly and easily with universal mounting clamps. Simply set the rack on top of your crossbars, attach the bottom portion of the clamp, and tighten the clamps down with the included tool.

To install the rack directly into the top channels of your crossbars, attach the T-bolts instead of the mounting clamps. Then just slide the rack into your crossbar's channels and secure it using the included socket wrench. To access the carrier's mounting hardware, simply remove the rubber strip on top of the base.

Video Transcript for Lockrack Adjustable Watersport Carrier Review

Colin: Hey everyone. It's Colin here at etrailer. Today we're going to take a look at a pretty cool set-up from Lock Rack. This is their adjustable watersport carrier. This carrier is going to be able to load up to one kayak, one canoe, or up to a pair of stand-up paddle boards.And right off the bat, the thing that I just really like about this set-up is that we have no straps to secure it. We don't got to run any straps around the hull of our kayak, and we don't have to worry about bow and stern straps, either.

We're able to just throw it up on our lock rack, get our hooks installed, and then we're ready to go.With my old J-style carrier, you can see I had my anchor mounted in my hood, and I have another one in the back. Just to secure my bow and my stern. That's not even to mention the straps that I had to run around the hull of my kayak.And after a long day of paddling, that's just honestly the last thing I wanted to do, was get all my straps out, untangle them if I didn't have them organized, and then get everything secured.Now, one down side of this rack may be that, if you're trying to get multiple boats or other accessories on your roof, it does take up a good amount of real estate on your roof rack. But if you've only got one kayak to haul, then that's not going to be a problem.Now first, you probably are a bit skeptical of how secure this is really going to be for your kayak. But as you can see, I'm really trying to shake this kayak around and move it.

And the entire vehicle is moving as well. So it's going to be just as secure, if not more than, those J-style or saddle carriers that require straps.Now whether it's on the bottom of a carrier, or even on the arms, we're going to have a nice, thick, rubber construction to both of them. That's just going to help protect your kayak from any type of scratches or abrasions, and it's also going to make sure it's got a good grip on your boat. It's going to help it not move at all, or scoot back and forth while you're traveling.Now, when it comes to unloading your boat when you get to the water, that's going to be nice and easy. Something that this carrier has that's not very common amongst boat carriers is that we have a lock with it.

So if you want to leave it unattended for a little bit of time, whether you need to run into the store, or the gas station. You can run in there knowing that your kayak is going to be safe when you get back.When we want to unlock it, we just take their key system, which is going to be a little bit funky. You just got to line it up with the lock and we'll turn it to the right. You can see our hook comes right out. We have to hold it in that position in order to pull the arm all the way out.When securing it, all you got to do is just push.

You can hear those clicks. That is the locking system making sure it is locked into place.With the carrier empty, we can take a closer look at it. Right away you see the arms over there are actually on their side. That's another bonus of this rack. We don't have to worry about stowing those in the vehicle, or even in the house when we get home. We can pull them all the way out, and you see on the side there's another hole on there. We can slide it into the carrier on its side, and it'll lock into place.Again, that theft deterrent is going to make sure that no one takes it without that key. And it's also going to help when preventing wind noise and drag, because you don't have that added height onto your carrier.Now you can see the center bar right here. That's how we're going to be able to adjust our rack. We have it at the widest setting right now. And that's going to be more than capable of securing your standard kayaks, canoes, or paddle boards. The reason we have it at its widest setting is because we do carry a wide variety of boats, so we want to be able to make sure we get those secured.If you do have a narrower boat, you can bring these in on that bar if you want a more secure fit for it.Now we do have a universal mount on our lock rack system. You can see we have it on our aero style bars right now. But this is also going to work well with round bars, square bars, and most factory roof racks.Now if you are interested in the T-track option, it is available. You just need to take the universal feet off and then you'll have that T-track option.Another benefit of having the arms on their side like we do right now is that we're only adding about 2 1/2 inches to the top of our cross bar. Which can come in handy in any low-clearance situations.When in use, the lock rack is going to add about 17 inches to the height of your roof rack, which is something to keep in mind for any low-clearance situations, like if you we're trying to pull into your garage.Now, as you can see, we also have two of our stand-up paddle boards loaded. They're very secure. You can see they're going to be ready for travel. Now, one thing I do want to point out is that the bottom one does have a little bit of play in it right here, you can see. But as long as that top one is secure, you're not going to have to worry about the bottom one moving at all.Another option you have when it comes to these carriers that can carry multiple boats is going to be the Thule Compass. Now, one advantage that the compass has is that it can actually carry two kayaks. However, you do have to make sure you strap down both kayaks. With the lock rack, we can only carry one kayak but we don't have to put up with any straps.Now we'll go ahead and show you how to get it installed. We have the front rack installed. The rear one is going to assemble and install the exact same way. First let's go over real quick the piece I talked about earlier. This is how you're going to be able to adjust the width of your rack, depending on the size of your watersport craft.Now, what we're going to do is line up the hole with the slot right there that's inside our carrier. I'm going to go on the outermost hole, so we're just going to line this first hole up inside there like so. Then we'll do the same on the other side.Might get a little bit stuck. There. Now it's lined up. And what we're going to do is install our two brackets onto the carrier. How we do that. We need to take off the rubber piece right there, remove the lock nut and spacer from the square bolt. Now we'll insert that through the bottom, and it's going to sit flush inside there.We'll reapply the rubber spacer. Just make sure you push on it, make sure it's stuck. Put the spacer back on. We'll feed it under and feed it up through from the bottom of the carrier. It comes up right there. Now we'll put a lock nut on, and then repeat this for the other side.Now we're not going to tighten down the lock nuts yet, so you can see that the brackets still have a lot of play. We're going to tighten those down when we get it installed on our roof. Now, with that being said, we'll take our bottom brackets and the hardware and get this installed on our rear crossbar.Now we're just going to set it on top of our crossbar. You want to make sure you have these turned to sit right on top. We'll just slide it all the way across. You want to make sure you get it lined up with the front one. Now we'll grab our other hardware real quick. Now what we're going to do to make sure we get it lined up correctly is that, I have the other one set up to where this bottom bracket is touching the foot of my roof rack. So that's just going to make sure that it's lined up almost perfectly.We're going to take a nut right here. We're going to put it inside the slot right there. I'm going to put my finger on it to hold it up there, and then turn it upside down. I'm going to drop a bolt in right there.We got to get that threaded on, so I need to push up a little bit and turn the bolt. Get it threaded on that nut. There we go. You see it pulled down. It's threaded. We'll do the same on the other side as well. Now we can repeat that for the remaining three.Now with our included tool, we're going to go around and tighten up all the bolts, and then we'll move on and tighten up all the lock nuts that are on top of our rack. And we do have an included 10-mm socket. We can just use that to tighten down the lock nuts.It doesn't have to be over-tightened. Just get it pretty snug. Now from there, we need to replace the rubber pads that go on the channels. Easiest way to do that is, we're going to stick one side into the channel right there, and pull it, and stuff it on the other side. We'll do that for both sides.Now, per our instructions, we are going to load up our boat upside down. If you feel that your boat is going to be better right-side up, it's going to be more secure that way, you can go ahead and do that. We're going to first get our boat centered on the rack. And then get our arms installed.Once we get it on from the side, we can just push it over. Now we installed our driver-side arms. All I did was, I pushed them in until they we're locked in place and just making contact with the kayak. Now I'm just going to get our other ones installed. Again, just push forward until it's making contact. Now give it one good push to lock it in place.Now as always, you do want to double-check and make sure that it's sturdy, and that's going to be good for the ride.As you saw, I didn't have to run any type of straps, so after a long day of paddling, it is going to be nice just to throw it up there, get our arms installed, and then hit the road.Thank you all for watching. That's going to do it for our look at the Lock Rack adjustable watersport carrier.

  • Using Lockrack Watersport Carrier on 2019 Subaru Outback Limited with 2016 Hobie Mirage Outback
    The Lockrack Watersport Carrier # 339-LRUNISETX will work on your 2019 Subaru Outback. I checked with the manufacturer and they confirmed that it will work on the factory crossbars with your 2019 Subaru Outback. This is an awesome rack and it won't have any issues carrying your Hobie Mirage Outback, but since it's rather long, you may want to consider using something similar to # MPG309 and # MPG308 to secure both ends of the kayak for some added security when traveling long distances.

  • How to Determine if Lockrack Adjustable Watersport Carrier is Compatible with 2019 Hobie Outback
    The Lockrack Adjustable Watersport Carrier # 339-LRUNISETX is design to carry a watercraft with the gunwales down. If you choose to load it on the hull or an additional carrier then that is your choice. I really don't think you'd be able to get another carrier to fit like you are thinking though. We don't have a fit guide for which watercraft fit with this carrier but I can give you some dimensions that you can use to determine if your 2019 Hobie Outback is compatible or not. This...

  • Is There a Max Width for Lockrack Adjustable Watersport Carrier # 339-LRUNISETX
    It's hard to give a max width range for boards used on the Lockrack Adjustable Watersport Carrier # 339-LRUNISETX since the arms of the carrier angle in and if you carry multiple boards you'll have more room on the bottom than on top. When this rack is fully extended out though it measures 47-1/2 inches which allows it to easily be wide enough to fit paddle boards.

    Both the Lockrack Adjustable Watersport Carrier # 339-LRUNISETX and Thule Hullavator Pro Kayak Carrier # TH898 will transport kayaks but the Lockrack does not attach to a Hullavator, they are different carriers. Instead, the Lockrack # 339-LRUNISETX attaches to a roof rack via clamps or a rack's T-bolts with its universal mounting hardware.

  • How to Carry a Canoe While 5th Wheel Towing with a 2016 Ram 2500 4-Door
    To carry a canoe with your 2016 Ram 2500 while also towing a 5th wheel trailer you need a front mount hitch, a roof rack, and a carrier or padding to protect your canoe. If you have the front tow hooks I recommend the Draw-Tite Front Mount Trailer Hitch # 65063 because it doesn't require any drilling or fascia trimming for the installation. If you don't have the front tow hooks then I recommend the EcoHitch # 306-X7900 instead which essentially is the same thing but it comes with the...

  • Comparing 339-LRUNISETX vs 339LRUNISETA Lockrack Watersport Carriers
    The biggest difference is that the Lockrack Watersport Carrier # 339LRUNISETA has a single pad that you use to mount your kayak, canoe, or SUP on while the Lockrack Adjustable Watersport Carrier # 339-LRUNISETX has 2 sets of pads that your kayak, canoe, or SUP rests on. The advantage of using the adjustable option is that if your roof rack does not use round bars you can actually ignore the middle black piece and adjust the pads freely from each other on your roof rack. This means that...

    For your 2017 Chevy Equinox I recommend using the Thule UpRide # TH599000 for your bikes because of how easy it is to use and you don't have to remove your front wheel to transport your bike. To carry your canoe I highly recommend the Lockrack Adjustable Watersport Carrier # 339-LRUNISETX for a few reasons. The first is that it can accommodate pretty much any boat style out there and the second reason is that this carrier has integrated locks that help grip your canoe and eliminate the...

This carrier clamps around your crossbars but if you have T-Slots you can use the Adapter # THXADAPT12 which can provide some security if you have locking crossbars.
