Video Transcript for Curt Safety Chain with S-Hooks Review

Hi there, safety-conscious haulers. Today, we're gonna be taking a look at Curt's dual S hook safety chain. These are available with either a 2,000 or 5,000 pound capacity, and both are gonna come in about four foot in length. This is an all-in-one safety chain solution for your trailer. So, you're gonna get one chain that has S links on each side. And is designed to take the center of the chain and attach it to a single point here on your trailer.

You can either weld the links on, or you could bolt it in place, or one quick way to get the chain attached to your trailers, to use D links, and that's what we ended up using today was just a couple of D links to attach our chain to it. You can get these quick links here at etrailer. And I do highly recommend those. They really make hooking safety cables to your trailer a whole lot easier. The links on our chain are gonna have a zinc plated coating on them to help protect against rust and corrosion.

So, this way, we don't have to worry about our chains succumbing to oxidation in the near future, which can weaken the links over time. So, if you got that coating on there, it's just gonna extend the life of our components here, making them last many years in service. On the ends, we'll have our S hooks attached on each side of the chain. And this gives us a quick and easy way to attach it to the safety cable attachments at the back of our vehicle. The S hooks should work with just about every shape, size and style of safety chain attachment.

There's a nice large opening here. And it's a small enough hook to where it should fit in even those smaller pesky hitches. But the opening's large enough for those thicker beefier hitches that have a very high rating on them as well. So, this way, you don't have to worry about having a small trailer that you wanna hook to your big truck and your chain's not gonna attach. You should have no problem with those bigger hitches as well.

Now, typically, these chains are designed to be attached to a single point. And when you have it attached to a single point, you would just wanna hook your chains up. But if you're hooking it up with quick links like we are and if you've got one on each side of the chain, you always wanna cross your chains. And that's only an option that you'll have when it can get up like we are here with one on each side. And crossing it will act as a cradle, so in the event of a catastrophic disconnect, it'll hold our trailer up off the pavement. If you just have a single attachment point there, you can't really cross the chain, so you don't get that feature. That's another reason why I do like having quick links. And that completes our look at Curt's dual S hook safety chain..

Ordered safety chains for my boat trailer. No problems, easy order, came on time and were exactly as described. I will use etrailer again in the future.



Working as expected. It has rusted some but that was expected as it’s use is around salt water 4 days a week. I am completely happy


The trailer hitch that I bought from etrailer for my CRV are fine, good quality and I had no problem installing it. The major problem is now that the hitch is mounted there is very little room between the end of the mounting bolt/nut for the hitch and the top of the muffler. The exhaust system is rubber mounted and normally vibrates away on those rubber mounts. With less clearance it now vibrates against the mounting bolt for the trailer hitch and rattles like a machine gun on acceleration etc, and every bump in the road. This is not good, I need a fix.


Besides the Curt safety chain which measured 46 1/2" (not the original 48"), all the other products are good high quality products and match the descriptions.

Everything is great, thanks!


Accurately described. Fast delivery. Best price I could find and the shipping costs were reasonable. Looks and feels like a high quality safety chain. While hooks do not have “keepers” they are large and heavy and I expect to have no problem with them. Very pleased with my purchase.


Excellent quality product, made in USA, delivered quickly along with several other excellent parts by etrailer. Highly recommended safety chain and parts supplier.


Got a newer truck the hitch is slightly different so I needed to lengthen the chains. This was the perfect solution.


As always with, the quality is exceptional, the product delivered is always correct and the delivery is quick. Great company!


Typical great service and customer care I have come to expect from Etrailer.


This trailer chain is exactly the way I hoped it would be! Perfect!
And the price is right too!

  • Link Opening Measurement of Curt Safety Chains # 80031
    I went out to our warehouse to measure the opening in the link for you on the Curt Safety Chain with S-Hooks # C80031. The inner measurement is 0.52 inches at the weld and the links are 0.66 inches on the inside so your 1/2 inch bolt will fit. I measured with a digital caliper so it is precise and have attached a photo to assist.

  • Do Safety Chain Extension Links Have to Exceed Weight of Tow Vehicle
    Safety chain extension links simply need to match the size and capacities of your current safety chains. For example, if your chains were 1/2" diameter with a 16,500 lbs break strength and 3,300 lb working load limit you would want the Threaded Quick Link - 1/2" Diameter # C82932. In regards to just the capacity for chains, the combined ratings of two safety chains should simply exceed the capacity of what you are towing. So for example two of the Curt Safety Chain with S-Hooks - 47" Long...

  • Longer Safety Chain Recommendation for Longer Curt Ball Mount # C45270
    Going with a longer ball mount like the Curt Class III part # C45270 which is 13 inches long will increase the clearance between the tailgate and your trailer jack. In most cases safety chains have enough extra length that it's not an issue but if you need longer safety chains we have the Curt chain part # C80031 which is 47 inches long and has a 5,000 lb capacity. For a weld on loop to install it we have the part # E950.

  • Recommended Safety Chains For A 7,000 Pound Tandem Axle Trailer
    The rating listed for a single chain, like the Curt # C80031 at 5,000 pounds of capacity, will double when two are used. So the # C80031 used as a pair will mean you would have 10,000 pounds of capacity. With that said, I am not a huge fan of the S-Hook design as it can be a pain to get the rubber retainer band piece over the hooks when it's cold out and they can break as well. If you are wanting something that has good capacity and has clevis hooks, which I prefer, check out the Reese...

  • Length of Curt Safety Chain with S-Hooks # C80031
    Thank you for your recent purchase from etrailer. The Curt Safety Chain with S-Hooks # C80031 that you purchased has an overall length of 48-inches (including the two hooks) and an actual chain length of 40-inches as noted on the product page. Since I do not know how much additional length you require I suggest you take a look at TowReady # TR63035 which has an overall length of 72-inches. Or if you need only another inch or two you could add on Curt S-Hook with Wire Keeper # C81820 or...
