4 Stars Cross bars

Randy from FL wrote (October 06, 2016):

Great product for the price. Had no problem with the install, I did have to change to hex head bolts (6 mm x 1.00). With the allen heads the wrench can't fit because it's too close to the roof, not a big deal when you compare the price of the other crossbars to this one. Clamps hold strong and bars are sturdy. Definitely would recommend this product to a friend.

The crossbars fit great! And are so easy to attach! Actually have not traveled with them yet but do not anticipate any trouble. The price was great, also!

4 Stars Good option for the cost

Got this to fit on a rental car up in Anchorage. For the price, decent quality.

5 Stars Unversal Load Bars

Chris from VA wrote (March 25, 2016):

Long enough to fit across 2014 Odyssey roof rails. Glad that I didn't buy anything shorter, these might have about an inch or two extra at the front position. I haven't noticed much noise, if any, at highway speeds. Not much clearance above roof for tightening screws, so I did replace screws so that I could use a box end wrench. I also used a piece of inner tube to improve fit around roof rails. - Note: I thought that these were originally listed as 54", but it looks like they are listed as 55" now.

I bought the Universal Roof Load Bars for my VW wagon. Great product for the price. Lot cheaper than VW roof load bars. Easy to install. Love it. Wish I have bought it soon.

Recently purchased a set of roof bars for my SUV, the product was well worth the price, received it in a timely manner. installed them immediately, had a bit of an issue due to the design of the bolts but once installed they held my cargo box with no issues. would recommend this product to anyone who is looking to save some cash.

decided to build my own bike rack ... these crossbars plus the Apex Upright Rack saved money compared to the name brand racks, I agree about the Allen wrench issue mentioned by other reviewers.

Ronald from CT wrote (July 09, 2015):

just the right product inexpensive, solid and easy to install , the supplied Allen wrench should have a shorter elbow to enable easy fit , I needed to cut it , although a plier works well for tightening the screws .

Mounted to Chevy HHR. Hardware alittle hard to install bolts would be better with hex head bolts instead of allen bolts because of how close it is to the roof. Going to change to hex head bolts because of this


Dick B. from MA wrote (May 22, 2015):

Price was right, fits secure, easy install, but had to saw off the short end of the allen wrench to fit between the roof and front side rails.
