Title: A should-have for transporting bikes with a hitch mounted bike rack
Review: So apparently you’re supposed to use one of these with a hitch mounted bike rack. Who knew? I’d been using mine for over a year until I read a review that said I should get one of these.One thing that had always concerned me about that was how much flex there is in the bike rack, especially going over large bumps. I’m happy to say that with this installed, I feel much more comfortable now. That rack doesn’t even move anymore.For those who aren’t familiar with what this is, it’s a simple strap that you loop over your bike rack and run it to your trunk lid to take some of the stress off of the hitch/rack. It’s a simple, cheap, device that just might save you a few hundred bucks in the case of a failing hitch/rack (not to mention damage to the bikes!).Installation was a breeze, although the strap that comes with this is VERY long. I suppose it has to be, since you might be using it on a van or something. For a small passenger car, there is easily three feet of extra strap here. I just wrapped it up and zip-tied it to itself. The (vinyl?) coated buckle was a nice touch. I’ve also used a lot of cargo straps and this one is one of the best I’ve seen, very thick.I can’t really think of a bad thing to write about this. I wish I had known about it earlier, I would have gotten one a year ago.

Title: A must for hitch bike racks
Review: I have had a Thule 3-bike hitch rack in my garage for several years, unused since I traded my SUV for a Civic. A few weeks ago I decided to install a hitch on my car so I could start using this rack again, and the folks who installed the hitch told me I needed this item. It does what it’s supposed to do, which is stabilize the rack. Without this strap, the bikes are really bouncing around. The only problem is that the strap doesn’t come with installation instructions, which led to some unnecessary frustration and concern that I didn’t purchase the correct strap for my rack. But a quick YouTube search (how to use a hitch bike rack support strap) remedied the situation and I was off to the races. I won’t try here to describe the correct installation procedure because a video is truly worth a hundred words in this case, but it really is simple.

Title: Great for added support
Review: This strap works great for our bike rack attached to my Honda CRV. I had previously used our bike rack that attaches to the hitch without the strap and the rack would bounce/move quite a bit. The strap helps to reduce any movement of the rack and provide additional piece of mind that everything is secure. It is really easy to attach and take off once you get used to using the strap.

Title: Nice accessory for piece of mind
Review: I purchased the CURT 18050 61-Inch Bike Rack Support Strap as added piece of mind on a 1,000 mile (one way) trip carrying 5 mountain bikes on our new Allen Sports 5 Bike Hitch Mount Rack. This was used on a 2015 Yukon XL (aka Chevy Suburban). Since the spoiler is plastic on this vehicle, I popped the rear glass and fed the metal strap hook through the top of the glass. I slid the hook in from the left side onto the edge of the sheet metal for the lift gate. I slid the hook to the center of the lift gate so the strap went over the center support for the rear wiper. The strap itself was easy to install. Just make sure you feed it through the teeth the correct way, and lift the bike rack a little as you tighten the strap to properly support the top of your bike rack. We drove over 2,000 miles in this configuration and the strap performed well and didn’t loosen up, even with the slight wobble of the bike rack from the tilt features. Our vehicle set-up is a bit tricky, but I just made sure not to use the rear wiper since the strap was running over the top of the support.

Title: Good accessory but not for our CX-5
Review: A good idea and a required accessory for the Curt 18084 bike rack. We returned it as it clips onto the edge of the hatch. Our hatch like many has a composite spoiler at the roofline. The strap would put force on the spoiler and I didn’t want to risk damaging the car. We returned the unit and are using a strap that wraps around the hatch body. With the strap installed the rack is very stable. Our strap also wraps around the bike’s upper tubes and provides a second means of securing them to the rack.

Title: It work for the missing allen Sport strap
Review: It work for the missing allen Sport strap. So I bought an Allen sport bike rack off of marketplace and it was missing a strap so I ordered this one. It was the same width on the strap part the metal hook Works perfectly fine but it’s not as wide as the one it original hook it came with it but it works perfectly. I would highly recommend it. It seems very strong, adorable, and it made my Allen sports bike rack from my car work perfect for me. Highly recommended.

Review: Works as intended. Used for 4x trips. Not had any issues of it coming loose.Hyundai Elantra with Raleigh 4x bike carrier (loaded with 3x Adult bikes), Curt 11424 class 1 Hitch receiver from U- Haul.- You need to secure the loose end of the strap to prevent it working the Ratchet loose (use attached velcro strap)- to tighten the strap have a helper lift the bike rack by the horizontal bars while you tighten Ratchet.- once all bikes are mounted, lift up bikes and rack by horizontal bar and confirm there is no “play”. Tighten Ratchet as required.- once tight, lifts rack 15°, back to horizontal. Does not require bolt on clamp on Hitch receiver.- bikes and rack stay locked to car on bumps, no bounce 👍

Review: This should be 10$ maximum. It works fine but has nothing special than 1$ of nylon and a 0.50$ clamp. It is an absolute necessity for a hitch mounted rack in my opinion. 4 star for the completely disrespectful price.

Title: Keeps our Thule rocket box from sliding around, better than Thule clamps.
Review: These worked so well, I wish we had gotten them years ago. No sliding of our box in high winds, even with a tornado warning. Easy installation too. We have a Thule box that we have used for well over a decade, and these are the best attachments we’ve found. Reasonably priced, too!

Review: They were a little too small for my THULE Adventurer box, but I was able to just drill new holes and they worked perfectly, even with drilling new holes it took all of ten minutes to install on our 2018 VW Atlas.

Title: They work!
Review: Arrived very quickly. It’s packaged semi haphazardly in a very small box. I have a set of no name brand roof rails and because of their shape was worried about the ability of these to work. But they fit well enough to be able to tighten everything down. The original roof box hardware didn’t work with these rails which is what sparked the initial search. There’s several to choose from but frankly they all look the same and this seemed to be a good value in comparison.
