## Description

Fits 2008-2017 Buick Enclave

Review: Easy to install, works well and looks nice. - Took about an hour to install, mostly because I did it alone and had to keep walking around the car to tighten bolts and such. An extra hand would definitely speed things up. I found a couple of Youtube videos that showed how it installs. I recommend watching one of those videos just so you know what to expect. Overall it's a solid product and it all went together easily. Pay close attention to the instructions. You may think they are not detailed enough but there are. One bar is shorter than the other and the brackets are side specific. Each one is marked LH or RH for left-hand or right-hand. LH is drivers side and that is called out in the instructions.
Review: Good price and was very promptly delivered - Came complete and delivered in very short time. Good price and was very promptly delivered. Comes with Torx T25 head wrench.Fairly easy to mount once you figure out how to do it. Instructions do not indicate how to remove "rear end siderail covers". To do so, just grasp firmly at end closest to siderail and pull straight up. They are tight but will come off since since each is mounted on pressure clips that become visible once you remove the cover. Did not need to use anything to pry them. Although not a GM produced piece, there is a "you tube" video that provides "How to" mount directions which help to understand the not too clear instructions. Suggest you split hardware for each side and for each crossrail (front crossrail is the longer one) ahead of time since you have a left and right side for each crossrail . There are 8 "tap plates" ( two for each of the four sliders) . They are inserted on slider's slots (see instruction's step 2); two of the slots are somewhat narrow and you may have to tap plate into slot . Make sure the hole on the plate is aligned with slider holes so at time of mounting crossrail's support ends to slider with screw, it "catches" and can be tightened. Same for thumb wheel (used for tightening when placing crossrails in desired position once they are mounted) Note that one end of each crossrail is adjustable so the cross rail can reach across width in question and that there is no need to tighten the screws mounting the adjustable ends.

### ⭐⭐⭐⭐ Overall a good product
*by S***R on September 18, 2014*

The product was a genuine GM product and fit our 2012 Buick Enclave very well. I have seen the reviews that suggest that the directions are hard to follow, but I didn't have any problems. I gave it 4 stars instead of 5 because the bolts that I received were extremely difficult to work with. The bolts have a 6 star opening (as opposed to a phillips type opening). Some of the bolts had a tiny prong in the middle of that opening and the tool they provided to crank the bolts didn't fit. I had to drill them out and use a different tool. Once the unit was on the car, it worked great.
