Good old duct tape... i would get some silicone caulking and run beads along the cracks in the box to seal the water out. not sure what colour that is but the caulking comes in many colours as well as clear.


please take a moment to rate this solution.. thanks

Strut on Thule Atlantis 1600XT popped off. How do I re-attach it?

Put your carrier on a pair of saw horses and clamp down firmly then open the lid as it now stable and clamp your strut with a wide jaw wood clamp. Apply just enough pressut to start the ball into the socket and finish with your hands. Steve Parks

The locks work fine when there's no gear loaded, but when i put my boards onto the rack the locks won't turn. any suggestions?

sounds like a pressure issue ( binding problem ) --- when you go to lock the locks ( with the skis and/or snowboard on rack ) try and push down hard on the rack while you turn the locks,, this might get the pressure off enough to allow the lock cams to pass. if this does not work then the next thing to do is to file down and modify the lock cams so they turn easier without binding. if you do not have the tools to do this modification then you can always go down to your local locksmith shop ( with the skis/snowboard on the rack ) and have them do the modifications -- the shop will only charge you around 10 to 15 dollars for this service.
I hope this helps,

The top won't open. First one side began to stick on the left front ball latch and now the right side won't open at all. Is there a simple solution? Should I sand down the ball on the left side? Can i buy...

When mine did the same thing, I just sprayed each mechanism with some spray lubricant to free it up, worked great. Same in the latches. WD-40 to the rescue.

Line crack of roof.

I have a solution for cracking of these Thules.
The stores that sell these, carry a patching kit. It's a 3x8" piece of the same material with adhesive on one side. You can take a heat gun and soften the patch and place it over the crack and shape to fit before it cools. I've had 2 Thules on the roof of my excursion with stress cracks at the anchor points. This stuff really does the job and it's really inexpensive.
I have them on both boxes at all stress points... It has solved this issue.

Fxing cracked carriers


As you know when a solid piece of material is damages, the structural integrity of the item is damaged, and it doesn't help that ABS is a very unfogiving material. I see Cartop Carriers all over my city with scuffs on them because the things are simply easy to forget that they are even up there!

In my research on your issue I found a material that should fix your cracked carrier and ensure that you will have many more years of enjoyment with it.

To answer your question, Fiberglass is not the proper material to use on ABS. Fiberglass is essentially a "Band-Aid" on ABS because the bond will only last a couple of years.

For this job you will need to use a compound called "Re-Plast" manufactured by the automotive parts company Wurth.

The benefit of Re-Plast is that it hardens into a plastic that bonds well with ABS, and it bonds FAST! So work quickly.

The Re-Plast will give your carrier a "scar" but should patch up your crack and increase your structural integrity. The good thing about Re=-Plast is that if you want to, you can paint over it to match your carrier's coat, to conceal the "scar" even better!

You can order Re-Plast directly from Wurth on their website link that is found below.

If this does not solve your issue, or if you have any more questions, please leave a comment on this thread and I will be more than happy to assist you further!

Happy New Year!

Feedback is appreciated!

Cracked thule box is what Thule recommends you use to seal your crack :) -- it is an ABS patch kit and is waterproof as it is used for permanent canoe and kayak repairs. it is NASA designed.

I am using it on my Atlantis 1800.
