5 Stars Apex RB 1004-49 Cross Bars Perfect

Judy from VA wrote (July 11, 2016):

On July 2 read the reviews on these cross bars and called customer service. Donald's assistance was superior. The cross bars arrived today and my husband had them installed in less than 15 minutes. They appear to be very durable. We are happy with the product and very happy with the customer service.

5 Stars Roof cross bars

Rob from FL wrote (July 07, 2016):

I used these cross bars today and they were very easy to install on the car and they are made very durable. I strapped my cargo on them and they worked very well... I would purchase again if needed.

5 Stars Great Racks

Jim from IA wrote (July 05, 2016):

This roof rack is exactly what I was looking for to carry kayaks side by side. The rack is easy to install and take off by just loosening one side and untightening the locking knobs and by leaving one side set it will go back on in minutes and in the same place. The racks are heavy duty construction and nice anodizing. Would recommend these to others at a good price.

5 Stars Perfect

Dean from WA wrote (May 30, 2016):

Purchased and used to tie our cargo bag on our cross country move. Works great very solid and sound product. It does make some noise if nothing is attached.

5 Stars Nice Rack!!

JroTull from FL wrote (May 03, 2016):

Very good rack for my Nissan Rogue SUV. I needed a rack to hold kayak brackets and this rack does the trick perfectly. Highly recommended. Simple attachment and removal too.

4 Stars Great but noisy at speed

Ben from TX wrote (April 25, 2016):

Does anyone know how to reduce the wind noise at highway speeds? Otherwise they're great bars. They take a little while to install in order to get them centered so it's not practical to take them on and off frequently.

5 Stars Awesome (but take note)

Rick from WA wrote (April 02, 2016):

These might be the best designed roof racks I've ever owned. These are FAR superior to the Thule's and Yakima's that I have used. If you're looking for something light and aerodynamic, these are not for you. If you're looking for a great locking system and something you could haul a house with, these are for you. Mine arrived quickly but with a hole in the box. After unpacking them I realized the keys had exited through said hole at some point during transit. Called customer service and had a new set in less than 5 days (Awesome customer service). They said if they couldn't find a set of keys they would just send another set of racks. Here's the take note part. The locking knob on the end turns to tighten the racks to your vehicle. It appears that as they are being built, lock tight is used to secure the bracket bolts to the thru bolt assembly. This lock tight leaks thru to the thru bolt and effectively locking it in place as well. I had to squirt some liquid wrench on the thru bolt and then turn the knob back and forth a few times, problem solved. Although somewhat of a manufacturing flaw, I was pleased to learn that they cared enough to use lock tight. Bottom line these are heavy duty built like a brick shipyard, ingenious locking device, and VERY reasonably priced for what you get. HIGHLY RECOMMEND a set to anyone looking.

5 Stars Quality product

Installed on my 2005 Tahoe, fit perfectly. works well with kayak carrier.

5 Stars Was Skeptical at First, but Really Great Bars

Bruce from AZ wrote (February 14, 2016):

I was skeptical at first and thought if I didn't like or they didn't fit, I would simply return. But fit great, very solid construction and clamps are solid as well. No part of it was flimsey. very satisfied and will Probably buy some matching accessories such as a basket and kayak racks.

5 Stars Heavy duty. Looks good.

Justin from WI wrote (February 06, 2016):

Only problem is that they make a howling noise at 55-65 mph. Otherwise I am very happy with them. For my 2012 Ford Escape nice and snug

5 Stars . Great product at a great price and is very strong

5 Stars Great Product for Kayak

Eric from IN wrote (July 13, 2015):

This product is outstanding and easy to install. My kayak mounted on top very easily. The lock system is great too so other can't steal the racks. I would recommend this product.

5 Stars Exactly what I needed

Mike from OH wrote (July 12, 2015):

After purchasing a used 2005 Honda Odyssey, I was disappointed to find that it's luggage rack did not have cross bars. Fortunately, I found these crossbars which are very simple to install. I added 2 pairs of J-Bar racks for carrying kayaks. It turns out that having these crossbars is more advantageous than the standard Honda crossbars. #1–they are not expensive like the Honda crossbars. #2—easy to install (as said before) and remove with the J-Bar racks attached. If I had the standard Honda crossbars, I would have had to deal with removing four J-Bars, which are a big pain to install. Thank you so much!

5 Stars Great deal!!

Patrick from CA wrote (July 07, 2015):

I had to have cross bars for a trip. I figured I would find some cheap bars that would do what I needed and thats all.. These bars surprised me beyond belief! The price was the first thing that caught my attention. Next was the 180lb weight capacity. That was more than enough to cover my rack and gear! The ease of use and sturdy construction makes these cross bars a steal. The locking mechanism is easy to use and safe. Everything about this product and purchase from this website was great!

5 Stars great product.

stan from WI wrote (June 30, 2015):

The cross bars from the honda dealership were $210.00 and not in stock.Ordered these on sunday and got them on tuesday,took about 10 minutes to install and feel rock solid.Can't wait to get the 17' wenonah canoe on them for the weekend!

5 Stars Excellent Product, Great Price

Dean Rettew from AZ wrote (June 24, 2015):

I searched for weeks for a universal crossbar solution that would fit my 2013 GMC Acadia. Nearly nothing fits my sidebars. I called a product specialist and they told me this one would work. The quality is much better than I expected. Very well built. The only thing I would add is a protective plastic coating on the bars. They were a little scratched right out the box but I'll get over it. They're so easy to use they almost install themselves. They are even better than advertised and I feel confident they will last a long time without issues. I was really close to spending nearly $200 on OEM bars but these are probably better quality and I can put them on any vehicle with raised side bars. These bars are money well spent.

5 Stars Stronger than I expected

Dan from WI wrote (May 29, 2015):

Easy to order. Just fit my 2010 Ford Explorer which was impossible to fit elsewhere. Price was very good and I received order in 3 days. Company's communication was great.

5 Stars Great product, full of details!

Jeff from FL wrote (May 11, 2015):

Great looking product made with details. I can see they put alot of thought into these bars. They are easy to install, I put them on the first time (tonight) in the dark, in about 5 mins. They are easy to size/adjust and then just lock in place. The are also very solid construction with good looking welds and heavy steel clamps. The instructions are easy to follow with 1 full page dedicated to tie down safety.

5 Stars Roof Cross Bars

JL from NY wrote (April 25, 2015):

These bars were easy to install on my Subaru Forester's roof rails. They are heavy duty metal, but the clamps are all rubber coated to protect the car. The clamps tighten easily without extra tools and it can even be locked. The bars will be perfect for carrying my canoe which is just a bit wider than my car!

5 Stars Great Solution

Larry from OR wrote (January 30, 2015):

I purchased this set of roof bars for my 2015 Subaru Forester. It fills the need for transporting all those oversized building material buys for the home projects. Easy on and off, clear readable instructions, great solid feel and secure fit. I took a short drive with the bars installed and only heard an occasional slight rattle on our well used streets. This is a solid, good looking, economical solution to the high$ factory bars and the name brand offerings. I will recommend it to all my friends.

4 Stars Rave roof rack

Dennis from MA wrote (January 26, 2015):

Works fine on my Subaru Forrester. Initial shipment had a lock problem with one end of one of the cross bars. The manufacturer replaced it immediately.

5 Stars Nice rack system

Jerod from OH wrote (December 15, 2014):

I ordered this for my 2014 Dodge Journey. These are an economical addition for me to haul my kayaks. Shipping was extremely fast even just a week before Christmas. Thanks for the great product.
