Video Transcript for Feature Breakdown: Thule Xadapt3 Xsporter Load Bar Adapter for the Hullaport
Today we're taking a look at the Thule Xadapt3 Load Bar Adapter Kit. Now this kit allows you to mount a Hullaport Kayak Carrier onto the Thule Exporter height adjustable load bar. So those load bars are a little bit thicker than standard aero blade or aero boars and so that's why this kit comes with the longer bolts. It's also designed to fit the Thule Cascades Ski Cargo Box. The adapter kit comes with eight bolts and the bolt size is M6 X 80 mm.That's going to do it for today's look at the Thule Xadapt3 Load Bar Adapter Kit.

As other reviewers have noted, allows you to mount your older Hull a Port Pro on a thicker, more aero crossbar (in my case 1.25”). I have two sets of Hull a Ports and was able to use just one set of the longer bolts on one side and the standard ones on the other.

The product is exactly as expected. The longer bolts enable me to mount my Thule kayak racks on a mini trailer. etrailer is great service and support. Product shipped quickly. Only 3 stars because it’s expensive for 8 bolts. Thule’s fault, not etrailer’s

Just what I needed...extra length bolts to fit my Thule Wing Bar Evo.

What can I say. Needed same sort of bolt only longer so it would accommodate a new & improved roof rack bar. Cleverly designed so you couldn’t just go to the local hardware store and…. Or specialty fastener store for that matter. Bottom line it secured my ‘J’s’ to the bar. Thinking of ordering another set. Any ‘deals’ for a return customer?

The screws were of right length and thread. Unfortunately...and it is not depicted in video...Square lock under the bolt head was of the wrong size.
original is a 7mm square, new bolt is a 5mm square. screw will rotate when tightening in the Thule.

Switched from square bars on my old cars to the evo bars- these are perfect to adapt my old hull-a-port pro kayak racks to fit the evo bars.

I purchased the THXADAPT3 to be able to install my Thule 834 hull a port kayak rack onto the 1.5" square bar of my Adarac Custom Truck Bed Ladder Rack - Steel with Aluminum Crossbars.
I believe it will work but I wish the bolts were a bit longer. See images.
I have been satisfied with etrailer's support and service.
Thanks

These bolts solved the issue when there was limited thread engagement on original bolts assembling hullaport kayak carriers on aeroblade bars. I've made many trips to the water without needing to worry a nut might vibrate off. Fits nicely, performs well. Would have been hard to find elsewhere.

Exactly what I needed for my Thule Hull-A-Port Pro Kayak carrier. These bolts allowed me to assemble the kayak J-Hook carriers onto the crossbars of my kayak trailer. Perfect fit.

I ordered Thule adapter bolts and was surprised at how quickly they arrived. I had intended to purchase them directly from Thule but their minimum shipping cost was [...] and their website indicated that the item "should" ship within 5 days.
I found the bolts at atrailer.com, shipping was [...] and they shipped the next day. A very positive experience!

These bolts should be included in the Thule Kayak carrier kit, since the kit claims to fit factory roof racks with 2" diameter cross-bars. They won't fit unless you have these longer bolts.

Called and spoke to Sam G at etrailer. He assessed my situation and needs, recommended the right product. I received my order quickly and had excellent communication from Sam G. I would definitely come back to eTrailer to order my roof rack or trailer needs.
Thanks Sam G!

I needed longer bolts to mount my Thule Summit on my VW Touareg. The OEM bars are very thick and the standard bolts are too short. These 80mm extended length bolts are the perfect solution.

These lag bolts work great just long enough for them to fit my Thule Kayak carrier.

Emailer provided amazing customer service for a product that cost much less than the competition. They emailed me to confirm the order when i placed it, again when it was shipped, and then today to verify that the order was delivered. Delivery was fast and well-wrapped. This was a great purchase experience.

- Long Bolt Kit for the Thule Hull-A-Port to Allow it to Install on Thicker CrossbarsSounds like the # THXADAPT3 is exactly what you need. This comes with 8 M6 bolts that are 80 mm long that are designed to let a Thule Hull-A-Port Kayak Carrier # TH834 install on taller crossbars like it sounds like you have.

view full answer... - Glide On Style of Kayak Carrier Recommendation for 2006 Nissan Xterra with Factory CrossbarsI checked with Thule and for your 2006 Nissan Xterra with factory crossbars they list their Thule DockGlide Kayak Carrier with Tie-Downs - Saddle Style Carrier part # TH896 as a confirmed fit. This is a glide-on style of kayak carrier that would fit and work well for you. Check out the review video I attached for more info as well.
view full answer... - Recommended Kayak Carrier for Adarac Ladder Rack on 2016 Ford F-150For your Adarac Custom Truck Bed Ladder Rack, like the Steel # A70490, that you have installed on your Ford F-150, I recommend using the Thule Hull-A-Port Kayak Carrier # TH834. The Adarac crossbars on the systems we have available for your truck feature dimensions of 1-1/2 inches tall and 1-1/2 inches wide, which will work well with the Thule Carrier as long as you add the Xadapt3 # THXADAPT3. This kit just includes longer bolts to help with proper mounting on these larger crossbars. If...
view full answer... - Adapter to Attach Thule Hullaport to Truxedo Elevate Ladder RackSince the Truxedo Elevate ladder rack # TX84NV that you have has top channels the adapter you'd need for the Hullaport XT # TH848 is the Xadapt part # THXADAPT3 which allows you to utilize the load bar's top channel for attachment.
view full answer... - Do You Have Parts that Will Allow Me to Fit My Older Thule Hull-A-Port on My WingBar Evo Crossbars?I have a solution for you. I confirmed with my contact at Thule that the older style of Thule Hull-A-Port 835PRO was originally designed to fit Thule square crossbars. However, Thule confirmed that the the Xadapt 3 Xsporter Load Bar Adapter # THXADAPT3 will fit your older-style Hull-A-Port and give you long enough bolts to fit the carrier onto your WingBar Evo crossbars.
view full answer... - Which J-Style Kayak Carrier Will Fit on Adarac Ladder Rack BarsI have a solution for you, but the Adarac Custom Truck Bed Ladder Rack # A46FR for your 2015 Chevy Silverado 1500 short bed has slightly different shaped crossbars; however, we've dealt with this before and I have a great solution. The Adarac crossbars on the systems typically have dimensions of 1-1/2 inches tall and 1-1/2 inches wide, so you'll just need to use an adapter or different bolts to accommodate the bar size in most cases. I recommend starting with the Thule Hull-A-Port Kayak...
view full answer... - Does Thule Compass Carrier Fit around Thule Wingbar Evo bars?The Thule Compass Kayak and SUP Carrier # TH890000 is a great fit for your 2020 Honda Fit. It has a wide mouth to make it easier for loading kayaks. It also has nice adjustability like J-style for one kayak or post-style for two kayaks. I attached a screenshot where Thule gives instructions for installing it on your Thule Wingbar EVO crossbars. You need to use the 80mm bolts included with this carrier to install it onto your bars. For your older kayak carrier like the Thule Hull-A-Port...

- Will the Thule Hull-A-Port # TH848 Fit 1-1/2 Inch Square Crossbars?I have a solution for you. Unfortunately, the Thule Hull-A-Port XT will not be able to fit onto a square 1-1/2 inch crossbar. However, it will work if you purchase the Thule Xadapt3 # THXADAPT3. The longer bolt sizes that come with the Xadapt3 will allow you to attach the Hull-A-Port to your 1-1/2 square bars.

The Replacement Bolt for Thule Sidearm part # 915-068-054 that you referenced is just a replacement bolt so it will be the same length as the bolts you have now and will not work. The Xadapt3 has longer bolts which will then allow you to attach your Sidearm to your new crossbars. You will need one kit for...

view full answer... - How Tall is the Thule Xsporter Ladder Rack and Will I Have Enough Cab Clearance to Haul my KayaksThe Thule Xsporter Pro Adjustable Height Truck Bed Ladder Rack # TH500XT is adjustable up to 27 inches. This is an overall height adjustable measurement. I measured one that we had on hand, and this measurement is from the top of the base assembly (that attaches the rack to the bed rails of your truck) to the bottom of the load bars. Additionally, the load bar is 1-5/8 inches wide, so the total measurement from the bed rail to the top of the load bar would be 28-5/8 inches. I have included...

- Can the Thule Hull-A-Port Be Used on an Adarac Truck Bed Rack on a GMC CanyonYes. You can use the Thule Hull-A-Port Kayak Carrier w/Tie-Downs - J-Style # TH834 on an Adarac truck rack when you use the Thule Xadapt3 Xsporter Load Bar Adapter for the Hullaport # THXADAPT3.

I confirmed with my contact at Thule that this is the correct kit for your application.
view full answer... - Are There Thule M6 Carriage Bolts Available That Are Longer Than 75 mmWe do have M6 carriage bolts that are 80 mm long, check out the Thule Xadapt3, part # THXADAPT3, which comes with eight, 80 mm, M6 carriage bolts. The wingnut that you referenced, Thule Replacement Wingnut, part # TH04877, will work with the 80 mm carriage bolts # THXADAPT3, and the 75 mm bolts, part # TH915-0675-11, and # TH10403.

She did say that the other option you have is the # THXADAPT11 that would allow you to use the tracks of your Xsporter rack instead of going around the bars. Is it possible that the square shoulders of the carriage bolts of the # THXADAPT3 aren't seating properly into the mounting bracket of your Hullaport and that is why you aren't getting...

view full answer... - Can Thule Stacker Kayak Carrier Fit Thule TracRac Ladder RackYou can use the Thule Stacker # TH830 on the bars of your TracRac but you'll need to also use the adapter part # THXADAPT3 so that the rack will install in the top channels of the load bars.
view full answer... - Mounting a Thule Hullaport kayak carrier to Chevy Colorado Gearon Cross railsTo adapt your Thule Hull-A-Port, part # TH853PRO , to bigger bars, you'll need part # THXADAPT3. This includes 8 longer carriage bolts that will replace your existing bolts.

If you prefer to carry your kayaks at an angle, you need a j-cradle rack. The Thule Hull-A-Port Kayak Carrier w/Tie-Downs - J-Style - Fixed - Side Loading, part # TH834, will fit your TracONE ladder rack. You will also need the Thule Xadapt3 Xsporter Load Bar Adapter for the Hullaport,...
view full answer... - Kayak Carrier Recommendation for Thule Xsporter Ladder RackYou would want the Hull-A-Port part # TH834 and the adapter # THXADAPT3 to allow it to fit the Xsporter bars. This is the best kayak carrier solution we have for the Xsporter. Those bars are harder to fit racks to since they are so thick.
view full answer... - Will Thule DockGlide Kayak Carrier Fit Kargo Master Congo Cage on 2015 Jeep Wrangler UnlimitedAt 2 inches those crossbars will be just a little too large for the Thule DockGlide # TH896 to fit with the hardware that is included. You would also need the longer bolts, # THXADAPT3, which are 80mm or 3-1/8 inches long. Using the longer hardware will allow you to use the DockGlide without having to use different crossbars on the Congo Cage.
view full answer... - Availability of Carriage Bolts For Thule Cascade Ski Cargo BoxI spoke with my contact at Thule and they said the carriage bolts you will need for the Thule Cascade ski cargo box is the Thule Xadapt3 Load Bar Adapter, part # THXADAPT3. This kit will include eight bolts and the size of the bolts are M6 x 80mm, which are 3.15 inches in length. The Thule M6 x 75mm Carriage Bolt, part # TH10403, you have referenced will not be the correct bolt for your Thule Cascade ski cargo box.
view full answer... - Bolts Included with Thule Hull-A-Port Kayak Carrier Barely Fit Toyota RAV4 CrossbarsIt sounds like the Thule crossbars on your Toyota RAV4 are just a bit too tall for the included 65 mm bolts to securely tighten the Hull-A-Port # TH834 J-style cradles onto the roof. I do recommend going with the longer M6 x 80mm bolts # THXADAPT3 for your application to ensure a safe and secure fit. I spoke with my contact at Thule and he stated that the bolts should go all the way through to the other side on the end cap/knob for a proper installation.

I am glad we had the right bolts to be able to use your Hull a Port with the larger bars MRogers. Do you have a specific body of water you like to go out on? A few of us from work took the kayaks out on a stream paddle about a month ago, so relaxing and peaceful =)
