Video Transcript for In-Depth Review of the Durabilt Safety Chain Connectors for 5/16" Chain

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this Durabilt safety chain connector set. Now, this is going to provide two of these oversized links that will allow you to attach your 5/16 inch thick safety chains, or your slip hooks with a 5/16 inch throat opening so that you can get your chains quickly and easily attached to your hitch. And this is going to create a more accessible attachment point than the connection loops on your hitch. Now, this is a 3/8 inch diameter, tempered, grade 80 steel construction. So, it is gonna be very durable, gives us a safe working load limit of 4,500 pounds.

It's gonna be very easy to get these assembled. So, you'll just loop 'em around your hitch's safety chain loop on the one end and then we'll pass the pen through on the one side, get that lined up there like so and you'll hammer that pin in to get it through and then you'll have that other link there so that you can attach your chains so that it will be very easy for you, especially if your safety chain holes are too small for your chains. And this will give you a much easier attachment to make sure that your chains are gonna have a nice, solid attachment and be much easier to get connected and disconnected. These do have this corrosion resistant red powder coat to them. So they are gonna hold up well for you and overall just gonna be much easier way of getting your safety chains attached and making sure that they are going to have a nice, solid connection for you.

That completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

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.

by:
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:
Product appears well made, but was too small to properly fit my Ford F250 Super Duty hitch.

Byron we appreciate the feedback. As long as the part hasn't been installed and used, we can do an exchange or refund. If you're interested in finding the right size, let me know.

by:
The Durabilt Safety Chain Connectirs are exactly what I required to extend my trailer safety chains. Etrailer customer service is always to me and their staff is very knowledgeable. I will continue to be a customer with this company.

Thanks for the kind words, Bruce! Glad we had what you needed as well! ^___^ What kind of trailer are you pulling?

by:
Alot harder to put together than what the videos showed. Found it easier to install pin off the truck first, pop it back out and then install on the truck. Also placed a small amount of WD-40 on the pin to help it slide in easier.
by:
Very difficult to hammer pin for DIY install. Especially with no jack or tools to wedge hammer locks
by:
I haven’t installed it yet but a quick check and it fits my 2022 F150 (normal stock towing) and large tow hooks.
by:
Installation note: Even greasing the pin, it is a pain in the ass to drive the pin into position...:)
But once they are in place, it is a piece of cake to connect your 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.
by:
way too hard to install.

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:
Hard to assemble but very nice. When in doubt use a bigger hammer!!
by:
Could use a bit better finish, lots of surface rust after less than a year of use, but great product otherwise.
by:
Amazing! Heavy duty!! Easy to install and can't wait to tow with it!
by:
Great product, easy installation. Less then 5 mins .

Product is great . So much easier to hook chains up.

by:
etrailer instructional video was helpful in allowing a simple installation. The safety chain links are well built and a great design.
by:
Went on quickly key is to grease the pin and use a 4x4 block from your receiver height to the ground to hammer against with a large hammer. Good quality.
by:
It was a bit of a challenge putting the pin through the two halves, but I eventually found a way to get it done. Red matches the truck! Much easier to attach the trailer safety chains
by:
Ordering with etrailer was simple. Fast delivery, quality product, excellent communications with the seller, and the help videos will simplify installation. The safety chain connectors were a bit pricey, but they are top quality. You get what you pay for. I highly recommend. Etrailer never disappoints.
