This adapter kit allows you to mount a LockRack watersport carrier to your roof rack crossbars without an accessory channel. Includes 4 adapters and mounting hardware.

Specs:
I started my purchase by asking a question because the shown measurements didn't seem like the mount would fit my 2020 Toyota Highlander crossbar, but I got a response that the website measurements were wrong so I ordered a pack of 4. I definitely didn't use the mount as intended, but it mounted perfectly. I can see that these mounts could be used for a lot of different things for your roof.
Easy to install and the feet worked great for attaching ski racks to my Subaru Crosstrek.
Product allowed me to use my factory OEM roof rack with an awning on a crossover Jeep, my set up leaves a lot to be desired in the practicality of the space between the zipper and the roof rails but it works and my car doesnt look silly

As long as it works and looks like you want it to, that's what's important, Nick :)
The clamps let me put my Thule 78” square bars over my RAV4 factory crossbars, so that I can use it for two canoes or one canoe and a space case! Wonderful. It is removable and if I drill extra holes on the Thule bar it can fit any width of factory crossbars on other cars. The clamps are wonderfully designed. They take an 8mm or 1/4” Allen hex
Works like a champ on my 2017 Subaru Outback Limited 3.6R
required drilling a few holes, but seems to be working ok. Not ideal for converting the Yakima Haul Riser from the round to the oblong shaped bars
After scouring the internet webs I found these to help with a rack conversion and they are perfect and holding up great.
These adapters are the perfect size to fit on my Subaru Outback crossbars in order to keep my canoe from sliding side-to-side when blasting down the highway.
But what I really loved about receiving this package today is that it is packed SO perfectly and efficiently, tucked into their ziplock holding bag!!
You guys are great.
I needed an aero bar adapter to mount a Thule Kayak rack to my Hyundai Palisade.
Even though these aren’t advertised for Thule they fit perfectly and are rock solid!
Lightening Fast shipment! Received within days of ordering. Excellent communication, confirmation and updates on purchase and shipping.
I have used these to attach something homemade to the roof rack. I used silicone to retain the nuts in their recesses on the underside of the clamps as these nuts were not retained as the clamps are made. This made it easy to remove and reattach the clamps quickly.
The clamps themselves seem durable and strong.
The worked as expected and fit perfectly on to the racks. The nuts for the bolt fit into the bracket which made for easy assembly.
Product arrived quickly and is mostly as advertised. I was looking for something to attach to the Toyota factory bars on a RAV4, and I think these should work fine.
First, they feel a little flimsy for my intended adaptation, mounting bikes. Second, they bolt center distance is 3.75", not 2.5" as is stated in the "expert" opinion.
These were exactly what I needed for T-bolt mounting solution and fit perfectly on my 5th gen 4Runner cross bars that do not have a T-bolt channel.
Simple design that works well. Solid, low-profile. I used these to install Thule ski racks on GX/ 4Runner roof cross bars.
These were a lot better adapters than what it originally came with and they were cheaper. I used these in the Thule ski rack.
Great quality product. Help when adding my vehicle awning.
Excellent thank you!
They fit and seem sturdy
They work for my application, but I did have to use longer bolts.
Fits perfect I have a Vevor ski holder and they don’t sell spare parts so I’m very happy but will never buy a Vevor product again
They are exactly what I've been looking for for my Subaru Outback. Feel very durable and the hardware appears to be stainless steel, so rust shouldn't be an issue.
Very late and no follow up from the CSRs
screws and bolts strip. giant waste of money

Hi Michael, it stinks that this did not work for you. The bolts with this adapter are meant to be tightened down with an allen wrench. Let me take care of this for you.
High quality products. Just what I needed for my factory cross bars.

This mount has been going strong for over a year now. I have subsequently had to replace the yellow smiley ball, but the mount and additional hardware used to mount the ball has worked flawlessly.
