Video Transcript for Malone Foam Block Style Kayak Carrier Review

Hi, everyone, this is Angeline here at etrailer, and today we are looking at the Malone foam blocks for kayaks here at etrailer. This comes in two different ways, so you can get the deluxe kayak carrier, which comes with two foam blocks as well as tie-down straps, all that you need to tie down your kayak to your vehicle, or you can just get the foam block on its own. This comes in the size 18 inches as well as 24 inches. Malone has foam blocks in different shapes and sizes, depending on your needs. What we have here are the ones with indents towards the middle, because they are perfect for your kayaks, but if you're also trying to bring a stand-up paddleboard, we have some that are straight across, or short and squat if you have your larger boats or larger canoes. You can check them all out here at

These have the weight capacity of 50 pounds per boat. What I have here are the 18 inch long foam blocks. You can see how they support our kayak on this roof. They work with crossbars, and they fit most style crossbars, arrow, elliptical, and even your round crossbars, but you can also put them on your naked roof. Underneath, you have this non-skid rubber layer, and it's a good layer there, it's nice and thick, thicker than some of your other blocks, but what I'm most impressed of is its grip.

So, here on our door, you can see how it really grips onto the door. It has the same effect on your naked roof, which will really help and you don't have to worry about it slipping or skidding off of your roof. When you do mount it to your crossbars, you are gonna have to open up this opening just to wrap it around the crossbars. You may be worried about if you pull it too wide, if you might break it. Now, don't worry about it.

'Cause as you can see, I have it where it's angled all the way open, but it swings or springs back into place, and that's how strong that foam is. I'm actually pretty impressed by this construction. This is a very heavy-duty foam. You can see how I'm trying to make indents or trying to squeeze it, and it's really strong and sturdy. You can also see how this style has that indent towards the middle, and that's to allow for a better fit on your kayak.

If you have your stand-up paddleboards, they have a version of this that is straight across. So just pick the block that fits your boat. Once you do finally get it on your crossbar, it has a very narrow opening underneath, which means it's really gonna clamp on or hold on to that crossbar. You do have a little bit of a wobble there, but that's okay because once your kayak or your boat is on there, that's gonna hold it down and keep it secured. Let's take a look at some measurements. So, the width of the block is 4 3/4 inches wide. The height in total is about 3 3/4 inches. Now, this depends on your actual crossbars on your vehicle, or if you're using this on a naked roof, but on our factory crossbars, from the top of the crossbar to the top of the block, it's 2 1/2 inches. From the bottom of the crossbar to the bottom of the block, it's about half an inch. The blocks can be used on your naked roof or they can attach to your crossbars. So, let's take a look at the install process onto your crossbars. There's different ways to do this, depending on how much work you want to put into it. What I like to do is just start on the ends and just pull apart those ends to wrap around the crossbar, and then I just try to feed it through. And see, here, on our factory crossbars, which are actually on the smaller side compared to your aftermarket crossbars, they are pretty difficult to put on, which shows how snug they are to the crossbars themselves. I like it. It's just the first initial setup that can be a little tricky. Your kit comes with straps, so we're gonna start with the two black ones. These are the nine foot long black straps. And you're gonna insert them into your foam blocks. While we're here, let's talk about where you should put those foam blocks. If you have crossbars, of course put them on your crossbars. If you have this on a naked roof, try to imaging cutting your kayak into thirds, and then place them at each of the third points for the best weight distribution. Now, once you have the black straps installed, these will connect your blocks to your kayak, so secure them both together. Once those parts are secured, you then secure the kayak to the vehicle itself. If you're installing this on a naked roof, you can attach the blocks to the kayak first with them on the ground and then put them on the roof. But since I'm doing it with the crossbars, I've found that the easiest way to do it was to install the blocks first onto the crossbars, and then attach the kayak, but it's really up to you which works best, as long as they're both secured. The full kit comes with two green straps as well, and these are gonna be used to secure your kayak to the vehicle. So I already installed the first one, and we'll install the second one together. What you're gonna need to do is get the, the end that does not have a buckle, and you're just gonna have to throw that as far across the kayak as you can and then catch it on the other side. You're then gonna thread the other end through that buckle, and then try to get it as tight as you can on both ends. What I like to do is I like to hang one side down, then I tighten the other, and then the other, until they're both as evenly tightened down as I can get it, and try to get as best of a fit as you can get. If you do have a naked roof or a type with just normal doors, this is a great way to strap down your kayak. Here on our minivan, we do have the sliding door, so you can also take advantage of the crossbars already on your vehicle and just use the straps to strap it down to your crossbar. Either way will secure your kayak and your blocks to your vehicle. The deluxe carrier comes with bow and stern tie-down ropes that come with S-hooks, in order to secure them to your vehicle front and back end. Please make sure to install these to your kayak before you go off onto the road. But, with those installed, that's it, and that's how you install a kayak to your Malone foam blocks. My final thoughts about this foam block is I'm really impressed by the sturdy construction of the foam. It's really nice and durable. Now, it was pretty difficult to put onto our crossbars, and it took a little bit of muscle, but once it's on, it's on. I'm also impressed by the grippy underside, because I think it will really work well with your naked roof, as long as you strap it down properly, so please, try to pick the deluxe kayak carrier that comes with that tie-down kit, because that will help secure your kayak to your vehicle as you transport it. But all in all, I think this is a great start to your kayaking adventures. The foam blocks will hold up, and they will transport your kayak safely. And then when you're ready to commit to the larger or more traditional kayak carrier, you can find them here at etrailer. And that was a look here at our Malone foam blocks for kayaks here at

Average Customer Rating:  4.7 out of 5 stars   (27 Customer Reviews)

Replacement foam block for Malone kayak and SUP carrier (MPG171) makes it easy to transport a kayak or SUP on most roof rack crossbars and naked roofs. Foam blocks a safe surface between your vehicle and your boat. Straps and tie-downs not included.


This is not universal I struggled to get the blocks to fit my Thule Track rack. I would not recommend for a Thule rack.

Thank you for your review. The opening for the bar measures 1 inch in height by a little over 3 inches in length. I recommend to measure the roof rack bars before trying these.

Made these work on my Thule and then Velcro strapped them down and they work great.

We purchased these foam blocks (2) to carry our large Perception Tribe double kayak on our Honda CRV. They are perfect! Because our kayak is so wide and has a rather flat bottom, we needed long blocks Without a large U-shape curve to them. The 24” length and the slight V-shape indent are perfect to provide the support and stability we need on our roof rack crossbars. The shorter blocks we had tried previously allowed the kayak to rock too much. The blocks have a nice large opening for the crossbar. The foam material is quite stiff, so it does take some effort to get the block onto the crossbar, but once there, it is very stable. We just received them and have only used them once. We are anxious to see how well they hold up over time, being put on and taken off frequently.


As a single older woman, I found the foam pads difficult to put on my roof rack, but managed with the aid of a broom handle. Once on, and maneuvering my new kayak up on to them, I am very pleased with the end result! The pads provide the cushion and protection I had wanted for both the boat and my Subaru roof rack. Thank you.


They took FOREVER to get to me in the summer of 2021 because of COVID supply chain problems in China (2+ months), but since I've got them, they've done exactly what I've needed them to do. They're awesome!


Great blocks for my Savage River Falcon. 24" width helps as the normal 16" are nearly too narrow. Shipping from etrailer was very fast.


High quality foam kayak blocks. Will be storing our Hobie kayaks on them for the winter. Love that they are 24 inches and very reasonably priced.


Excellent product! Built to last!


Great product, fast shipping!


This product worked very well for me. The material is more dense than I expected which is good. It gives enough to support my kayak but not enough to allow the hull to be damaged in any way by the underlying support.

I still use it and it works fine.

A little tight to put on my rack but snug and perfect to lay the cockpit of my upside down kayak on.


Very happy with these blocks. THey fit snug on my trailer bar. One of my fishing kayaks does not have the typical V shaped bow and this block is the only one that I have found that supported it. Great purchase!


great product.


Product was delivered in a timely manner.
It was a pleasure doing business with ... :-)


Worked great for supporting my kayak.


Product looks great & arrived in very secure packaging.
The folks at etrailer were super responsive to my inquiry & product delivered sooner than expected.



Awesome product, it works perfectly for me!!


Exactly what I needed
