Video Transcript for Review of Durabilt Trailer Safety Chains - DU55QR

Hello, everybody. This is Jeff at etrailer. Today we're gonna take a look at the Durabilt safety chain connectors for 5/8" size chains. Has an 18,100 pound working load limit. And as you can see, it is for a quantity of two links. Now these coupling links are gonna consist of two U-shaped metal pieces, which are connected with this pin and this retaining collar, so it allows them to move and rotate freely.

Basically, when you go to install these, what you'll do is start your pin through there, get the holes to line up, and when your pin goes through, you'll take your collar and put that right in the middle here, and you'll have to tap it in with a hammer to where it gets to the middle and then you keep tapping it far enough and it'll lock it in place and it'll allow these to rotate freely just like that. Now, these links are gonna let you attach safety chains to your hitch quickly and easily. They create a more accessible attachment point than the OEM connection loops that are on your hitch. Actually, the new Ford trucks have loops that are too small to accept standard size safety chains. So by attaching these to your OEM loops, that's gonna allow you to attach your safety chains to your vehicle.

Again, the application is for 5/8" thick chain or slip hooks with 5/8" throat opening. And the way you can tell is if you look on here, it is stamped with 5/8 of an inch to let you know. They do also sell these in other sizes. They sell them in a 5/16 size, which has a 4,500 pound working load limit. They sell it in a 3/8" size, which has a 7,100 pound working load limit.

And they also do a 1/2" size, which has a 12,000 pound working load limit. Those items are all sold separately on our website. And as we mentioned, the hammer lock design, that's how it's installed as I showed you. You'll take your pin, drop your retaining collar right in the middle there, run your pin through the holes. When it gets to the center, tap that with a hammer till it goes all the way through and it'll lock it in place.

To remove it, all you have to do is take a hammer with a punch and then punch that pin out so you can remove it. The material on these is a tempered, grade 80 steel construction. As you can see, it's a nice corrosion-resistant, red powder coat finish on it. Again, working load limit, safe working low limit is 18,100 pounds per link. Now also, if you do have any other additional questions regarding this part or any other item that we carry, please feel free to reach out to us so that we can help you get all of your questions answered for you. But that's gonna do it for a look at the Durabilt safety chain connectors for 5/8" size chain.

If you have a General Motors heavy duty truck bumper poles 18,000 pounds you will need these to hook your chains up. Install went very easy with a 5 pound sledgehammer. There’s a reason why these are rated for 18,000 pounds they are definitely heavy duty. The only way you’re gonna get them off is with an acetylene torch.

Been using them for over a year now. Have only found one issue they are too large for smaller trailer chain hooks. Fixed this problem by getting 2 hooks that will fit over the eyes. Placed a smaller on the connector of the hooks. Leave them in my truck to use on any smaller trailer. Would still recommend too anyone wanting to tow heavy.

Order arrived quickly. Went on easier than expected for some of the other reviews. Just a little grease on the end of the pin and a 4 pound sledge drove it in without a problem. 2016 Chevy 3500 HD.

It is working great. Best solution out there.

by:
They don’t fit on my Ford F250 as well as others on your videos. Also the pin and lock that I use still hits them and I have to work around it where the video said that wouldn’t be a problem.
by:
This is perfect!! No more fighting my trailer chains!!!
by:
Very easy to install…. I think I did it faster than the guys on your video. This is so much better and safer than the hooks that I was using before…. Thank you very much.

Thanks for your feedback Gregory. Was there a specific part of the install that was difficult? Sharing here can help others make an informed decision regarding an upgrade like this.

by:
They are well made, went together nice and tight so they will not come apart easily. Can't wait to try them with my Camper and Trailers.
by:
Amazing! Heavy duty!! Easy to install and can't wait to tow with it!
by:
Should have gotten these 3 years ago! GMC has a terrible design on their trailer hitch receiver where you attach the safety chains So hard to get chains hooked to it. These are awesome and a great solution! They fit perfectly and are super easy to install. Just need a big hammer to set the pin in place. I have multiple trailers from a boat trailer, flat bed car trailer and utility trailers. Safety chains on all of them now hook right up!
by:
Just what I was looking for.

i placed my order and with in 10 minutes i received an email that the connectors i purchased where out of stock. i then called and talked with Diane and she was able to hook me up with the next size up.

Exactly the item we needed. Delivered in a timely fashion and etrailer consulted me about another item I had ordered. Turns out, we didn’t need the item and the cancellation was simple.
