Rigid Mount Design

This rigid-mount coupler fits tightly within the channel bracket (sold separately) for a secure and rattle-free connection. Four mounting bolts with nuts are included for installation.


Hexagonal Grooves

Hexagonal grooves are cast into the inside of the coupler's channel to hold the nuts in place for you as you tighten the bolts down when mounting the coupler in your trailer's channel bracket. This not only makes installation faster and easier, but it also allows for a tighter fit that eliminates movement and noise. It also reduces any jolting that occurs during acceleration and braking.


Collar-Lok Connection

Collar Lok

The ball-and-socket joint of the coupler keeps the hitch ball captive by providing a continuously tight fit. Within the socket, the ball retains full range of motion so that it can rotate in any direction to keep your trailer from binding up.


To hook up your trailer, simply lower the coupler over the hitch ball and close the hinged latch around the ball. Then slide the Collar-Lok over the latch. When the collar is in place, it not only protects the hinge joint, but it also gives you visual assurance that the latch is securely closed. As a final step, slide in the coupler pin. This pin is chained to the coupler so you won't lose it. Because the pin hole is angled instead of being straight up and down, inserting and securing the pin is easy.


Spring-Loaded Hinge

Simply reverse the steps to unhook your trailer from your tow vehicle. Slide the pin out and push the Collar-Lok back.The spring-loaded hinge will pop open for a quick release. A built-in stop tab will keep the jaw from flinging out too far as the coupler opens. The stop tab is a unique addition that prevents the hinge from overextending.


The latch has a force-transfer feature to add stability as the ball is forced against it on bumpy roads. This keeps the hinge joint and latch from breaking or torquing to extend the life of the coupler.


Downward Bias

The downward bias of the coupler improves the angle at the articulation point and allows for a better connection with the hitch ball. The result is better support for heavy loading and a nice, streamline look.

Video Transcript for Review of Bulldog Adjustable Trailer Coupler - Coupler Only - BD028584

Today we're taking a look at a Bulldog collar lock coupler. This coupler has a weight capacity of 7,000 pounds. It's designed for a 2" hitch ball. It's a heavy duty coupler that lets you hook up your trailer to your tow vehicle. So it provides a connection point for a hitch ball. This is ideal for utility, livestock, cargo and construction trailers.It has a ball and socket joint that closes tight around the ball, so that allows for a multi-directional movement to keep your trailer from binding.

It has a spring loaded hinge with a stop tab, so that quickly releases without overextending.Now the collar lock design is very easy to use. We have this pin and clip here. That prevents it from being slid back and disengaging from a connection. We wanna remove that. That's held on there with a chain lanyard so we don't have to worry about misplacing that or losing it.Then what I'm gonna do is, I'm gonna slide this collar back.

And as I do that, this portion's gonna kick out. Which opens the socket to accept or release from a hitch ball. That kicks out just like that. Now our socket's opened and we can drop this over our 2" hitch ball. Then to move it to a secured position, all we have to do ...

I like to pull the collar back down, push in, then allow the collar to slide back over that area. That just provides a really nice, firm hold. Then we can replace the pin and clip so that way it doesn't accidentally slide back and disconnect from the connection point.The collar lock gives the nice visual indication that the coupler is securely closed. Again, it has the pin style fastener that holds the collar in place around the base of the hinge ball socket.It's a rigid channel mount design with the anti-rattle feature built in. If you look closely, you'll notice these indents right here.

They are designed to hold the hex nuts in place so you can easily tighten the bolts for a firm connection. This offers really nice contact with the hitch ball, also a nice clean, straight line look.It's an adjustable channel mount. So this let's you change the coupler's height depending on your application. It comes with four grade five mounting bolts, with lock nuts included. Your channel bracket is sold separately.We're looking at a heavy duty steel construction. It has a powder coat finish on it to resist rust and corrosion. It's SAE standard compliant. It's designed for a 3" wide channel bracket. We can tell that by taking the measurement outside edge to outside edge right here. Measures just shy of 3", so this would fit into a 3" wide channel. Then it would attach using the included hardware.Again, it fits a 2" hitch ball, weight capacity is 7,000 pounds. And the overall length from very back to very front's around 10".That's gonna do it for today's look at the Bulldog collar lock coupler.

Like that it is a heavy duty hitch, like the way it locks and attaches to the ball. Don't like that is doesn't have a handle/lever on the collar to push it on or pull it off. 481680

Review from a similar Collar-Lok in Adjustable Trailer Coupler


This is exactly what I was looking for. This is a very good heavy coupler. It is replacing a 5K surge brake toledo bulldog coupler on a trailer I have beefed up with 600# of steel to the 10K level. To save $$$ and maintenance issues I am going to electric brakes after I decide on current axles or not. Very speedy shipping: I did not expect to see it untill 16 July 12. I have ordered from you several times and you have always exceeded my service expectations and your prices are very competitive. 47860

Review from a similar Collar-Lok in Adjustable Trailer Coupler


Best coupler ever - well worth the slightly higher cost. Very easy to operate and slightly more tolerant of misalignment with the ball when hitching up. I keep a plastic deadblow hammer handy to operate it. Way more secure attachment then the cheap Mau coupler that came with trailer which came uncoupled by itself. 310645

Review from a similar Collar-Lok in Adjustable Trailer Coupler


Easiest hook up there is. The first time I bought one of these connectors I was in Texas. They are easy to find out there. Well I have a problem with my tow vehicle. It has a spare tire hanging right on top of my receiver ball. The connector that came with the trailer required about 6+" of space between the ball and the tire, which I did not have, I could lengthen the ball out which I definately wanted to avoid. This connector was the answer to my situation. I went up north last weekend to visit my son and when I got back this connector was setting on my front porch, this was about 4:30 PM. Before I went to bed it was installed on my trailer, after I cut the existing one off ofcourse. This connector connects up like a dream, it's self centering, has no adjustments, so you do not have to worry if it is too tight or too loose and may come apart. I modified the toung on my last trailer also and used this same connector, it's neat, sweet and compleat. I may be in the market for a load leveler kit. 337

Review from a similar Collar-Lok in Adjustable Trailer Coupler


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. 469915

Review from a similar Collar-Lok in Adjustable Trailer Coupler


Excellent Coupler with low price. I replaced the older Bulldog hitch with this one. The channels made it easy to weld it onto 3" channel iron. I prefer the low profile style, instead of the high profile model. I also purchased a lock from etrailer.com that goes through the hitch, replacing the normal clip that it comes with ( pn 28012). They also shipped me a 2" receiver hitch lock ( pn 7683) for my truck, and they keyed the two locks to the same key. 191173

Works great. Welded it on and was ready to go. Have ordered from etrailer before, and just like every time before my parts arrived very promptly and have never had any complaints with service. Will definitely be using etrailer again. 265563

Replacement for worn out receiver on old trailer. Wish Bulldog were made in the USA, not Mexico. But, the others are made in China, which is even worse. 92372


Comments
No problems. Remember to keep a hand on the lever when squeezing shut and let the slide close gradually so you dont pinch your other hand. I keep mine lubed with bicycle chain lube with Teflon. Also, i always grease the ball. Yes, that is messy but the metal-to-metal squealing is prevented and your coupler will last forever.
