Video Transcript for Curt Clevis Hook with Spring Loaded Safety Latch Review

AJ: What's up, everybody It's AJ with Today we're going to be checking out some CURT clevis hooks. These are going to be a great for attaching to the side of your trailer if you're tying down something on a flatbed, or for safety chains on a gooseneck, like we're going to show you here today. The spring-loaded latch helps it stay connected at all times, that way it's not going to pop out there while you're going down the road. Let's take a closer look at it.Look at them all next to each other, you can see the big size difference. We have the 5/8 one, which is our big, heavy duty one.

Now the 5/8, actually, is talking about the clevis pin here at the end and its diameter, so it's going to fit through those bigger chains for our heavier duty applications, like maybe a crane. So if it's lifting a load up like that, you're more likely to go with this big heavy duty chain. It's a little bit of overkill for safety chains like we're going to do today.Speaking of that, this is the one we're going to use today. It comes in at 7/16, because the diameter of the clevis pin fits through our chain we're using today for our safety chains. So it's going to be a good hook to use right here with our safety chain loops, and we'll show you how to install it in a second.

Our other size would be 1/2, and it's a good, in-between our heavy duty and then what we're going to use on the safety chains today. I've already removed the hook from this side, and this is the one we're going to install our new hook on. I just wanted to show you the old one and how the pin's wrapped around the clevis pin here at the end.The Cotter pin, you just kind of bend it around to keep that pin in place. So we took pliers and we just bent those straight to pull this Cotter pin out. Going to our new Cotter pin, that's in there straight for now, but we're going to bend it when we install it.

So we're going to just use some pliers, pull that out, take the clevis pin out, put it in between the hook here, install our clevis pin back in there, and then drop our Cotter pin back in. With it installed, now I will bend the Cotter pin backwards to keep it in place. There you go. So now you can see, you can't pull it right back out.I'm going to come down to our safety chain loops and just put our hook in there. You can see it's not going anywhere.

Let's put some pressure on this latch and see what happens. See me pulling on it, trying to catch the edge of it That's good, because it takes a little bit to push it back to even get it to spring back, and that way, if the safety chain loop does catch or anything, it didn't seem like it was easy pulling it out or pushing it around, so you don't have to worry about that at all. The clevis hook we're keeping today has a weight rating of 40,000 pounds. Now, obviously that's going to change the bigger and the more heavy duty the hooks get, but they are all a grade 80 steel with zinc plating, so you know that they're going to hold up.Clearly there's a bunch of different variables on which hook you we're going to go with and what will work for you, it really depends on what you're going to be hauling and using it for. But with whatever one you go with, I think I really like the latch system on the hooks because I don't have to worry about when I'm going down the road. If the hook was just in there, and sure you can tighten it down, it'll stay in place if you get it nice and tight, but there's always that chance in my head while I'm driving down the road that's like, "Oh, I'm going to hit a bump. It's going to come undone." With these spring-loaded latches, it's not going to happen. It's always going to stay secured around, whenever you have it secured around, like this loop or on the side of a trailer, or just the chain itself, it's going to stay connected. So I really like that part. I think that does it for our look at the CURT clevis hooks. Hope this helped.

Heavy-duty clevis hook provides a strong connection point for a variety of applications. Rugged alloy steel hook has a 1-1/4" opening, a spring-loaded safety latch, a keeper pin, and a weight capacity of 48,000 lbs.


This is the perfect Clevis hook for all the Ram 2500 and Ram 3500 goosneck towiing. As most of you know the standard clevis hook that comes with gooseneck trailers is to small to fit the safety chain "pucks" ram has to offer.
You can switch them out to this Clevis hook and be on your way.
All the best and safe towing my friends.
Thanks Etrailer.


I needed a large heavy-duty set of safety hooks to secure a Military vehicle to a low-boy trailer. We wanted something you could grab hold of with a work glove and not fumble around with a small item that might become unlatched. Your 1/2" hook fills the bill. This is one bid bad boy hook. Thank You All.
Attached is a shot of our truck on her trailer.


Just what we needed and now our hooks are slightly overrated for our trailer, we feel completely safe with these new safety hooks. And delivery was timely as well, no complaints at all with anything! Will use your website again for some other things!


Hooks worked great for gooseneck trailer and factory Ram trailer connections


So far I havent used this product yet due to just recieving it today. By the looks of it, its everything I was looking for.


Great product perfect match to the one that I already had . Thanks !

  • Available Safety Chain Hooks to Connect Chains to a Curt Gooseneck Ball and Hook Set
    I recommend upgrading both the chains and hooks on your trailer, like # 49150. Without knowing the capacity of your current chains, picking a replacement hook with the matching weight capacity will be impossible. Replacing the whole chains set will be the best option. I have attached a link that will take you to our safety chain product page. Once you know what weigh capacity chain and hook you are needing for your horse trailer you can choose one from this page.

  • Snap Hook Recommendation that is Compatible with the Reese Elite Pop In Ball Kit for Ford # RP30137
    I was able to determine that the Curt Clevis Hook Part # C81980 that has a 1/2 inch diameter hook will work on the safety chain loops of the Reese Elite Series Pop-In Ball Kit # RP30137. I pulled the two products from our warehouse and test fit them and they are compatible. I attached a video that shows them being tested together.

  • What Size Hook Will Fit Curt Safety Chain Loops # C60691
    I spoke to my contact at Curt an he said a 1/2 inch diameter clevis hook would be perfect for use with the Curt Safety Chain Loops # C60691, so a 3/8" diameter clevis hook will fit just fine. If you don't already have them, I recommend the Curt Clevis Hook with Spring Loaded Safety Latch # C81980. It's 1/2"diameter, features an 1-1/4" opening and has a capacity of 48,000 lbs.

  • Will Curt Clevis Hook Attach to Curt Class V Hitch?
    The Curt 81960 clevis hooks you referenced have a 1" opening, and the safety chain loops of Curt hitch # C15802 are approximately 1-1/8" wide so you would be able to use them, but the hooks would not quite close. For Curt clevis hooks with a larger opening there is the # C81970 which has a 1-1/3" opening, as well as the # C81980, which has an opening of 1-1/4". I've added links to video reviews of these hooks for you to take a look at as well.

  • Safety Chains and Hooks for Curt Ball and Safety Chain Loop Kit
    To fit your Curt Ball and Safety Chain Loop Kit # C60618, you need hooks that can fit over the roughly 1" wide top and 3/4" sides. You could use the Curt Clevis Hook # C81980 which has a 1-1/4" opening. This hook has a lot more weight capacity than you need but should fit just fine. I've added a link to a video review for you to take a look at.

  • Troubleshooting Safety Chains that Cant Connect to Class V Trailer Hitch Chain Loops
    Without knowing the diameter or your holes and the thickness of your chain loops, I can only give you some accessory options like S-Hook with Wire Keeper # C81830, S-hooks like # 6495-716-33, and clevis hooks like # RM-910031. The best option is the clevis hook like # C81980 if the chain loops are too big for your quick links. I've linked the page to all your options for these parts to assist.
