With this racks easy on/easy off approach it is hard to beat. Add to that the ability to swing the arms down when not in use and rack up to 4 kayaks with one low price... you have yourself a winner!
It seems the only way to transport 4 kayaks on your car, or the cheeper way to transport 2 kayaks.
I had a problem when I tried to mount kayak by myself: I had to use one hand to hold kayak upright, while with the other hand I tried to tie it in - not an easy job and not a safe one.
I returned it and got Thule Hull-a-Port instead. More money, but so-o-o easy to use. Love it.
For the second kayak I got THULE SlipStream. It is big and expensive, but it allows my wife to mount her kayak by herself.
Easy to put the boat against the stacker. Easy to tie on..
Drove from detroit to chicago with NO issues at all.
Takes abut 10 minutes per boat, for a beginner
Enjoy...
Another great product from Thule! These install quickly and are durable. I carry to boats with ease. The stackers come with lashing and ratchet straps that are very durable. They fold down easily on the rack, or they can be taken off in a matter of minutes.
Now we feel safe and secure traveling with boats!
is a great unit i have been able to haul 3 kayaks on top of our Grand Cherokee a 14.5, a 14, and a 12 foot kayak. haven't been able to haul four though, had to put one more kayak in our camper, but other then that they work great, and would recommend the stacker to anyone.
The old model seemed much more sturdy. The knob that you twist to lock the stackers in position must be stripped on one of my stackers, because when I put the stackers in an upright position and attempt to lock them, the stackers will still fold down. A friend of mine has a crack in the plastic tip of the stacker from the force of tightening down straps. The new model stackers are still functional, and I still prefer Thule over yakima (all attachments slide on round bars). I believe the older model is the 510 or 520(?). If you can find the older model new, I would certainly recommend them over the 830. Other factors: The 830 looks better. The old model rusts. We'll see if the 830 rusts!
I'm using the stacker with the Thule canoe attachments (small L-shaped pieces that attach to the crossbar), and it works well holding the kayak. I'm not sure how well it would work without these. Probably fine, but it's definitely easier with the canoe pieces.
