Video Transcript for Thule Roof Mounted Carriers 3-Wing Low M6 Hand Knob Replacement Review

Hi everyone. It's Evangeline here at Etrailer. And today we'll be taking a look at our replacement part, which is the Thule M6 low hand knob for your Thule roof mounted carriers here at Etrailer. So this is a direct replacement knob for your Thule roof mounted carriers. And like what we have here is we have a kayak carrier, which is the Thule stacker, and you can see how we're using a knob for both the carrier itself, as well as the clamps used to clamp down the carrier. So if one of them gets lost, damaged, or is broken, this is what you would get to replace them.

This fits right onto your M6 carriage bolt, kind of like what we have right here. So if you don't have an M6 carriage bolt, this will not thread onto it and make sure that's what you're using to clamp down your roof mounted carriers. All you need to do is just pin it around the bolt. And that's pretty much all there is to installing this replacement knob. Now the thing about this wing nut is that the thread is kind of deep on the inside.

There is some space that you have to clear before it threads onto your bolt. So just to make sure that if you're using this to replace something lost, and you're not sure which bolt you need, or which replacement part you need, make sure you have enough thread on that bolt for this to fit onto. So from my experience of working with Thule roof mounted carriers is I definitely recommend picking up a couple of these as you get your accessory, just because it is really easy to lose these nuts because of once you do release them, I've dropped them several times onto our floor or on the roof of a vehicle. So just because of that, this is a great piece to have around as a replacement part for if you do lose, break or damage, your current knob that is on your roof mounted accessory. Again, this is designed for Thule roof mounted accessories.

This may or may not fit whatever other accessory you have, but as long as it has an M6 pattern on that fault, it probably will fit. And that was a look at our Thule replacement hand knob for your Thule roof mounted carriers. Again, this is the M6 low hand knob and you can find them here at Etrailer..

Just what I ordered, now I can use my Thule Hula-port kayak carriers again. Perfect fit. Only if they came with a leash so I don't loose them again.
Thank you,


Fits perfectly on my Thule kayak rack, and arrived quickly. comes to the rescue again!


Quick easy replacement parts for Thule racks. Wish the plastic didn’t degrade so fast.


I was amazed to easily find exactly what I needed to use my ski attachment with my bike rack! Thanks!


Perfect replacement parts to repair the deflector on my Thule carrier rack.


Easy site to navigate and product was shipped as promised on time, I would highly recommend


It’s great I can so easily get replacement parts for my Thule roof top saddles.


Worked as expected. Perfect fit for the Thule surf rack


Exactly what we need.


Perfect replacement


The product was exactly the replacement knobs for my Thule rack. Delivery was as promised and fair price. I will continue to use etrailer for product replacements.


Fixed a broken part on my kayak rack. Somewhat difficult to find. Pricey but an exact fit. I ordered spares. Delivered very quickly.


Exactly as described and OEM


Reasonable price and quick delivery.


Perfect sized replacement part


The knob looks and fits exactly as the original lost one that secures my Thule stacker. Thanks for giving me a great description. That made it easy to assure I had the correct part. No fussing with a wrong part. Checkout was easy too. etrailer has the most informative and helpful site I have ever seen, and I shop a LOT. -CP in Washington.


As usual, lighting fast order processing and shipping (and Great pricing). Always a pleasure to do business with.

This carrier is great. I have my power cords, camp chairs , and sunshades up there. Not a leak, even through this terribly wet summer we had.

The product is exactly what I had asked for. Delivery time was reasonable and the service excellent.


Initially sent the wrong part, mistakenly sending the M8 instead of the M6. Once contacted they sent the proper part and didn't require me to return the original piece, which I appreciated. My only complaint was that the original shipping was very delayed due to low staffing, then there was the product error and as a result we were unable to use our kayak racks and were forced to rent kayaks because ours were sitting unused in the garage due to the delayed shipping and wrong products. So, these couple of inconveniences ended up being rather costly for us. That said, did do the right thing by us, it just took a while.


This is an exact OM replacement part that was easy to find on Although it is a part that needs to be replaced every few years it is hard to locate even on the Thule site. Price and shipping were good and the parts (I ordered extras) arrived as promised. I will definitely recommend this company and will return for rack or trailer parts.
