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 Bulldog Collar-Lok in Adjustable Trailer Coupler


I bought this old really cheap to rebuild. One of the parts that had to be replaced was the hitch, I towed it home with my fingers crossed. I googled trailer hitch, trailer and etrailer was one of the sites that was suggested. I had to find a hitch that fit the 3 1/2" pipe that was the tongue, voila there it was to my amazement. I ordered it right then, 4 days later it was delivered yesterday. Today I mounted it, it was an easy installation and I am really pleased with the hitch and install. My fears of losing a trailer are now history, tomorrow it gets tested with 1 1/2 yards of gravel for the slab for my new. shop 663229

The coupler was received filthy dirty, with huge runs in the paint, rust spots, and chips down to bare metal. A young child could have done a better job painting it. In addition, the holes for the trailer jack are poorly punched. 339423

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

The couplers (3) are of excellent quality. Ordering was very simple by telephone. All questions were answered. Shipping was immediate and the product arrived in an unmolested box which surprised me due to the weight. I expected the box to be dented and the corners smashed. Tracking of shipments was important to me. Couplers will be installed on a rather unique vehicle. Each of the three cars of this miniture train will receive the new couplers. 109607

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

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

Review from a similar Bulldog 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

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.

Products are as advertised. Metal and castings are good quality. Units handled prep and welding nicely. Only two minor points of annoyance. One of the spring retainers arrived broken at the clip end. A spot of delicate mig welding re-assembled it. The paint on all four units was thick enough to inhibit both the lock pin holes and the ball cup pivot actions. A bit of rat tail file work and some oil rectified both. 666248

It take a bit of getting used to, but you can certainly tell this is a best in class hitch. I pulled my 2006 crew cab longbed 7500 lbs. truck across the country on my PJ car hauler... Once at new home I used trailer\hitch to haul 4klbs. - 5klbs. of fence material - no worries... 659720

We ordered this on 5/27 and installed it on a burial vault trailer. Two weeks later, the pin holding the collar together fell out while in transit. 659505


Comments

Was the snapper pin secured correctly? The only way I could see this happening is if the bail wasnt secured over the snapper pin and it wasnt closed.

I recently sold a dump trailer that had a Bulldog 2 inch hitch on it. The new dump trailer I purchased is smaller but has a Chinese 2 5/16" hitch for some reason. I really like the Bulldog style and since everything else I have is 2", I purchased this to replace the one that came on it. As a self employed mechanic I have recommended my customer's use etrailer for supplies I use for them. They and I have always had a pleasant experience. Thank you! 656327

Hitch clamp is great quality material but sometimes hard to open. This is because the sleeve does not have support lever to pull back. I have a similar hitch that has a lever which pulls the sleeve when it needs to be opened. That makes it much easier. 617422

Review from a similar Bulldog Collar-Lok in Adjustable Trailer Coupler


I looked everywhere for a round coupler for my Tube-Neck trailer, then I found etrailer! I used it to replace the original, which was a thin steel coupler, that had been "pounded-out" until it was round!? This coupler is 20 times stronger. I had it welded on at the local welding shop. I took it on a 800 mile Hunting trip to southern Arizona last November. Not once was I the least bit concerned about the trailer, knowing that this strong coupler was now keeping everything connected. I gave it 4-stars, because the wire connector between the locking lever and the sliding collar, can easily be bent, and then can come free from the locking lever. Instead, it should be a solid steel piece, that is more firmly attached. 615520

Beefy hitch, lot of area to weld to. These are old school design, been around for years. My welding shop said go Bulldog or stay on the porch. Using it to add 7" to my TH trailer toung so I can mount generator box and have turning clearance. Lock the collar down and no need to worry about it. All our oil field company's use them.
