John from FL wrote (June 10, 2016):

I like how sturdy the cross bars are. After you have installed them the first time you discover something that is lacking in the instructions. The instructions lead you to think that turning the knobs in the counterclockwise direction will spread the inner and outer pads when it only puts a gap between the knob and the uter pad. You then must se physchial force to move the outer pad against the knob. This should be annotated in the instructions. Other than that the test installation was successful and will surely do the job.

5 Stars Awesome bars

Evan from DE wrote (June 05, 2016):

Just put these on my 2008 Jeep Patriot yesterday. Easy to put on. They are a little longer than my rails but that's fine. That's what I wanted. I do like the fact they lock. Also like the fact that they are very light, they seem to be well made and strong. Very nice price also.

5 Stars roof crossbars

Mark from SD wrote (April 13, 2016):

Just received the roof crossbars, they fit perfectly on my 2014 Honda Pilot. They are sturdy construction and easy to install. The only thing I would change is to have locking knobs on all four clamps. They arrived much sooner than I expected,ordered on a Sunday and they were here on Wednesday, standard shipping.

5 Stars Fantastic product!

Happy camper from FL wrote (March 15, 2016):

Great value here! This product looks good, works like it's supposed to, easy on, easy off, and handles up to 150 lbs of cargo! Can't say enough about it and extremely happy with my roof cross bars. Saved hundreds of dollars, other manufacturers are asking $600 for the same thing. Thank you discount ramps!

This crossbar is smart, easy and solid. It's quick to set up and fast to breakdown when needed. Cool and stylish product with sleek look and good hardware. The lock (two keys included) is a nice assurance that the crossbar will stay there until YOU take it off. Fits great on my SUV and perfect for two 12' kayaks. Great for any use where you carry up to 150 lbs. Need a crossbar? Get this product now?

5 Stars Roof Rack works great

Jeff from IN wrote (June 08, 2015):

This is a very sturdy rack and is easily put on and taken off. I use it to transport my 2 kayaks. There is a minor whistling noise travelling with the racks, but I think that is to be expected with any racks. Works great!!!!

5 Stars Met our needs perfectly

Dale from CA wrote (April 03, 2015):

Wanted a product that would fit both our vehicles. Bought the RB-1001-49. The cross bars work on my 2006 and 2011 Honda Pilots. Bar has snug fit on the 2011 but attaches without problems. Also required crossbars that could be easily removed, as they cannot be driven in the garage with the added kayak mounts. Good value and flexibility met all our requirements. Would recommend this product to others.

Just purchased and trying today. Story to be cont. . When we received the product, it was missing straps and instructions. Called customer service and they were sent to us right away.

5 Stars Exceptional product value

Terry from WI wrote (January 19, 2015):

Bought these as a trial, as I didn't want to spend the bigger bucks for a big name. We've traveled 1000 miles with rhem thus far and fell confident we will experience no problems regardless of weather and driving conditions for a lot of miles to come. They attach to our roof rack with ease, lock very efficiently, support 150 pounds, and glide quietly whether under load or sitting by themselves. Highly recommend the product to all.

5 Stars Good quality,

Rafal from VA wrote (December 19, 2014):

Easy to install and tightens down without any problems. Quick to adjust, durable and will not mark the surface of your existing roof rack. 53" fit perfectly on my Buick Terraza. The seller was great to order from.

5 Stars Great Value!

Jim from NH wrote (December 09, 2014):

I purchased the locking aluminum roof bars and found them to be rugged and well built. They are aerodynamic and the built in rubber strip on top helps prevent slippage. They were easy to install on the factory roof bars on my Ford Escape. They work well carrying skis and hauling stuff to the dump.

5 Stars RB-1001-49 Aluminum Roof Cross Bars " Great Product "

John from NY wrote (September 30, 2014):

These bars are super. They are very well made, are easy to install, do not cause any noise when driving and also look great on our car. Anyone needing cross bars that can be taken on and off often eaisly should buy these. The end clamps that slide along the bars make adjustment very easy for any side rail width and the knobs make attaching to side rails a snap. Great Product. Well worth the money.

5 Stars Exactly what I wanted

Dan from WA wrote (September 28, 2014):

I ordered these thru Amazon for my 2013 Suzuki SX4 Crossover. After reading the simple, clear installation instructions, the installation was done in 15 minutes with NO problems, no tools needed! The fit was near perfect for the existing roof rails, adjustments were easy, and the overall installation was strong and solid. BONUS, the ski box and kayak rack from my previous Forester bolted right on! If there's a down side, I can't see it. These are just as good as the "big name" manufacturers', and MUCH less expensive.

5 Stars A great product

Peter from MA wrote (September 23, 2014):

We surveyed many cross bars. When we installed this set, we were very pleased. They are sleek looking, so they don't appear to be something added to the car. They are very sturdy, and should have the strength to bear any load we put on it. The locking mechanism never seems important till you go to your car and the bars are gone....that's happened to us. These cross bars are comparable to the ones that cost many times the price in looks and sturdiness.

5 Stars Look and feel like $300 cross bars!

Rocky from NJ wrote (September 16, 2014):

These bars fit perfect and installed in less than 15 minutes. They really look nice on my 2012 Jeep Liberty Jet. Delivery was fast. The build quality and material leave me no doubt that they will support the 150 pound rating.
