Expensive little box

  • Familiarity: I've put it through the wringer

I have had this box for about seven years. I agree that the assembly process was less than fun but not a deal breaker. The main appeal of the box for me was the size. I just wanted additional cargo space and this fit the bill. As far as quality goes, I would agree with most reviewers that it is pretty flimsy for the price tag! One of the ball and socket joints on one of the hinges on my cadet separated so the box lid no longer holds itself open on the back half of the box. Not a huge inconvenience but it never should have happened. Also I had to drill additional holes on the underside of my box in order for it to fit the luggage rack spacing on my bars. This apparently voids the warranty. Thank goodness, I have never had to get any service from Thule. Would I buy this product again, nope! Would I recommend it to a friend, nope. Has it served its purpose sure so I guess it just depends on what you need.

I love it.

  • Familiarity: I've used it several times

It was a little difficult to put together but the box is great. It hold a surprising amount of stuff in it and I didn't notice any strange noises when driving on the freeway. I also like that is fits well with my smaller car.

Its Crap

    $15.00 worth of parts, about a buck spent on engineering, and zero on quality control. Thi s unit consits of two pieces of thin plastic, two hinges, four u-clamps, and two locks that froze in the locked position after just one year. For something without very many parts, it was very hard to put together. Sure, you can put your golf clubs in it, so long as the golf course you're going to is a par 3 and all you need is a 3-iron, 7-iron and putter! It can all be yours for JUST $260!!

    Yes--assuming you have a rack on top. If you have a factory rack, though, you need to double check Thule's website ( to ensure the brackets will be wide enough to fit over your crossbars. The brackets that come with this box are designed to fit round, square and most factory crossbars, but check the website just to be sure.

    Will this fit on a LExus GX470? Also what kind of accessory do I need to mount this. Thks.

    Go to, then use the Rack your Car feature. Or call customer service, they can figure it out for you.

    Thule's fitment guide is hard to get answers on. You'll probably have to e-mail them for a good answer. Use this address to ask, and they will answer by e-mail.

    Will this work with a 1997 Land Rover Discovery series 1 factory roof rack system?

    As long as you have somewhat standard crossbars, you won't have any problem.

    How much does this cargo box weigh? My factory installed roof-rack bars say that they support up to 100 lbs. Do I need to order different bars, or is the box itself pretty lightweight?
