Rob: Hey everybody. Rob here at etrailer.com. Today we're going to be taking a look at the Bulldog collar-lok adjustable channel mount coupler. Here's what our coupler's going to look like once we have it installed. There's a few different reasons why you might want to replace your coupler that's existing on your trailer, for us, we actually picked up our trailer used and it had a lunette ring and that's not what we have on our truck, so we wanted to match everything up using a ball mount so that we can hook up to our truck without changing too many things.Another reason why you might want to replace the coupler, is if you have a traditional style coupler like here, those use a wedge to go right up against the ball. As I lift up the handle, you can kind of see it moving on there.
Over time those can wear out, and it's really not as good of a connection point because the collar-lok is going to have a lot more pressure that's going to be going on the ball and not allow it to wear out right here.But the collar-lok is going to work a little bit different, instead of having that lever on top, the collar is going to slide back like we have here, and this side of the opening here is going to move out. Whenever we attach our ball and hook up to our truck the collar can slide back just a bit, allowing that side piece to come in, and now the collar will slide back over providing constant pressure so it's not going to allow the ball to move around that way. That way there's going to be continuous contact with the ball, not to mention there's a lot more contact because it's entire side piece is going to be pressing against the ball.Not to mention the collar style is going to give us a visual that we know that it's locked in place, because the collar is going to be all the way forward. With the traditional style latch couplers, the latch can come very loose, start wiggling around, and you're really second guessing if it locked in there or not.Now our coupler is going to be rated up to 15,000 pounds. It's also going to use a two and five 16th inch ball, and that's going to be pretty common on most construction, livestock, and utility trailers and it's really, really good for those just like we have here.Now this is designed to fit a three inch channel that's going to be on your trailer, and then it's going to be separate, but it does come with all the hardware necessary to get it installed.
The spacing between the mounting holes is going to be two inches, so you want to double check your channel on your trailer.Whenever you do install, you just want to make sure that you torque all your hardware down to the specifications in the instructions. What's really nice is that the coupler could actually be painted to match your trailer, or a bright color, so it stands out in case you have it parked in the lot and you don't want to run your leg into it.We went ahead and pulled our truck up to our trailer, just want to make sure that that collar is open, and that section sticking out. We'll set our coupler right over the ball, and then we can start lowering it down. Once the jack's off the ground and you know the couplers all the way on the ball, just want to pull that collar back slightly so it's not putting so much pressure on this side piece. We can slide it in, and we'll walk that collar over.
We can take the safety pin and make sure we go all the way through the coupler and come right out the bottom. We can latch it down. That'll prevent the collar from sliding back and the ball opening up.Now that we're finished hooking up our trailer, we're ready to hit the road, and that'll finish up your look at the Bulldog collar-lok adjustable channel mount coupler.

Don’t buy this!!! It literally does not work. You can’t open the coupling because it was built incorrectly. There isn’t enough room to slide the coupling back. Of course I didn’t realize this until I had mounted it on my trailer. etrailer customer service is about to get an earful!
Great site. This is the second time that I have purchased items from etrailer. Your web page is easy to use and I like the product videos. The trailer couplerI bought was very good and fit properly.
Works great
I changed out the conventional ball hitch on a dump trailer to a bulldog style hitch. There were issues ensuring the original hitch was on the ball correctly. The Bulldog hitch will eliminate that potential problem. Installation was easy. Took about 10 minutes to get the old hitch off and the new one on. The only improvement that I would suggest is to have the lever to retract the collar as the lighter Bulldog hitches do. This one simply has a sliding collar that must be forced back by hand. I always use my foot on the hitches with the lever. But this is a Bulldog issue and not an etrailer issue. etrailer service was outstanding.
We have several of these 2 5/16 inch hitches, this is by far the best we have. Each component is heavy duty and well-made.

Still bullet proof. Only one we use.
I installed it this afternoon. It was a direct fit no issues.
Disappointed to see made in China on it. I had hoped to I would bulldog was a American made product.
No the less it will be usable, I hope I don't run into use issues down the road.
The new Bulldog hitch fit my old trailer perfectly. Very sturdy coupler. Works so much better than the old OE hitch.

one year later and the Bulldog is as strong as ever no problems..
Received the Bulldog coupler faster than What I Expected. Product is as described, with the exception of the small chain that holds the locking pin, it is about 2" too short, I had to remove it from the under latch to get the pin out. Now I can install it on my equipment trailer to haul a small excavator, without all the hassle of the old coupler that would not unlatch without a fight. THANK YOU!
The bulldog Collar Lok is excellent for our rental concrete trailers, as it assures the attendant that is hooking up the trailer the hitch is locked in place. This product is also study and handles the demanding conditions of our job-sites.
This is going to be a great replacement hitch for my utility trailer. I pull a 14,000 pound tractor and attachments on this trailer. The original Bulldog hitch that I am replacing, that came on the trailer, was easily damaged. This hitch solves this problem. Thanks
Prefer this style for it's simplicity, no doubt if the ball is properly latched.
It's already on my 14,000 lb 14 foot dump trailer. It's a perfect fit and nice to have a hitch as sturdy as the rest of the trailer. The original coupler didn't hold up.

Outstanding hitch. The service from etrailer is excellent, this package arrive speedy fast and is exactly as described.
The collar is way to hard to slide back and lock open. Since this item is a 15000 lb rated tongue weight coupler the base that has the 4 bolt holes should be beefed up some instead of a hollow core.
Lots better hook-up then what came with my new trailer. My wife can hook up by herself. Thanks
Just a great coupler. No other coupler but bulldog should ever be bought by anyone ever. Fits perfect!
The hitch parts worked out really well. Just what we needed.
Thank you.
Bulldog quality and very timely shipping…arrived exactly when promised!
