Video Transcript for How to Install: Durabilt Safety Chain Connectors for 1/2" Chain on your 2018 Ford F-250 Super Duty

Hi everyone. Aiden here with etrailer. Today we're gonna be taking a look at, and showing you how to install, these hammer lock coupling links from Durabilt on our 2018 Ford F250 Super Duty. So what these are gonna do is go through the safety chain loops on your truck here, and give you a good place to hook in your safety chains, whether you've got these oversized ones, or maybe some smaller, more standard sizes. That gives you a nice, easy place to connect because the safety chain loops on our F250 here aren't very easy to hook up to. You can see the smaller one, there's not really a great way to get it on there.

Maybe right there is probably okay. And with the larger, more oversized hook I can hook it on. But getting it off, I've gotta get it at just the right angle to unhook it. It's just not easy. It's not really easy to do.

And you might have some fitment issues with these larger hooks where they just don't fit at all. So having this extension over here makes that hook up a lot quicker and easier, and maybe you have less clearance issues. You can get these in multiple sizes. These ones are gonna be the half inch ones. It's made of a grade 80 steel with a red powder coat to protect from rust and corrosion.

And these are gonna be a pretty hefty install. It's got a 12,000 pound safe working load limit, and the way you install it is actually feeding one end through, lining up this other side, dropping the pin through, and physically hammering it through this center portion and out the other side. Definitely more involved on the install process, but the end result is something that is not coming off. Comparing that to something like a quick link that you can just loop around and thread close. Now this would be way easier to put on, but someone could come by and take it off, and overall it's not as big of an opening as our Durabilt option.

So again, for those larger safety chain hooks this might be a better way to go. That install process can be tricky but we'll walk you through that right now. So starting off, putting the two pieces together around the safety chain loop, and putting the pin through the first half, just like that, so it'll hold itself, putting our center ring through the center, and just pushing this until it'll hold itself in place. Now with this, you can just start hammering away and try to drive it through, but we definitely had some issues getting this in place, because there's not a great place for the link to actually bind up against the hitch. So what we're gonna do is actually apply a little bit of spray on the end of the pin here to help lubricate it and drive it through, and use a floor jack to try to bind this up against the hitch and hold it and place a bit better. So we've got it wedged up in place right now where it's pretty stable. I'm gonna start hammering, depending on our success level, I might switch it around and try to bind it a different way. It really just comes down to however you can get it to hold still and stay in place while you're hammering. There we go. We can lower down our floor jack, make sure everything's going through the other side okay, and we're good. And overall, it didn't take us too long to get it installed. It was really just some trial and error with finding the right place to bind this up so it would hold itself still. Some other trucks that we've done these installs on, there's more room to kind of wedge it against itself in a way, but with this specific truck, we had to use the floor jack. It worked out pretty well. Now we've got a great attachment point for our safety chains on a 2018 Ford F250 Super Duty. Thanks for watching..

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:
I haven’t installed it yet but a quick check and it fits my 2022 F150 (normal stock towing) and large tow hooks.
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:
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.

Awe, thanks for saying all that, Anthony! I'm glad that we can give you the quality you deserve.

by:
Just what I needed on my Ford F250 hitch.
by:
Right item for chain extensions on a truck with a 6 inch drop hitch, and I can relax because it's rated for the trailer weight.
by:
Good product delivered in a timely fashion.

Great product

by:
This product is absolutely worthless on the consumer level. I attempted to use a floor jack to give the unit some resistance while hammering (as suggested in the video), but the locking pin did not budge. The only positive of the whole experience was that I discovered my truck was missing the floor jack, which I've now purchased.
etrailer should not sell this product to anyone other than a full mechanics shop.
by:
Solid and fairly easy to install. So much more convenient than trying to hook onto the factory hitch.
by:
Ordering from E trailer is a no brainier.The Durabilt chain connectors are a great product.The problem I have and the reason for 4 stars is the color,a sort of blood red and every trailer hitch I've seen is black.They didn't look good on my hitch.I took them to the powder coater as soon as I got them to sandblast and re-powder coat black,you can't paint powder coat and expect it to hold up over time.
by:
Installed easier than expected with 4lb sledge and holding it close to the head. Quick clamp no good to install the lock pins. Added a few layers of Gorilla tape to protect the front and back of the red locks during install. Color is very close but not exactly the same as my "Ruby Red" 2017 SD. Paint will scratch off with use, but not very easily. Seems well made as I want. 4 stars instead of 5 because there were no instructions or info to let you know if the mm or so of play the pin has once installed is normal. Once the pin is in place securely, it may wiggle back and forth and it's fine. But there's no info on it for dummies like me I guess. That's a minor issue and I'm happy with my purchase so far.
by:
Works...but expensive
by:
Excellent product to improve safety chain hookup.
by:
Finally a proper way to attach safety chains!
by:
Garbage. Even following the directions in the video a very difficult install. I’m 2 hours in and only 1 side has been installed. There must be better products on the market.
by:
Great product. Make sure you lubricate the pin, it makes installation much easier.
