Ratings & Reviews
I have other brands of coupler lock, and they have basically a hitch ball that fits into the coupler. This one has more of a post that fits into the coupler which is why it does not fit securely in the coupler.
I will be returning this lock.
I ordered two of these locks keyed for both of my new trailers E TRAILER. ROCKS
We use these for our company trailers. As well as some personal stuff. And we have several. I like that fact that you can select your key number. It's nice for a business to have all locks keyed the same. Much less confusion with the guys in the field.
Just what I was looking for! Perfect fit on our 27 ft 2021 Jayco travel trailer with 4.5 inch wide coupler.
The lock seems extremely robustly made. My trailer has a wide flange around the coupler and the stepped design of the bail fits perfectly. The circular keyway is secure and the casting is smooth. The teeth on both sides of the bail provide more secure latching than my one-sided prior lock. The main lock piece is smooth on the bottom preventing someone from hooking under the lock and just towing the trailer away. My prior lock had a lip that allowed the trailer to be moved with a tow hook.
My only complaint is that it came with two very sharp, very pointy metal pins sticking out of the bail, maybe to secure it in the package. I had to get a pair of pliers to remove these before they ripped my hands up.
I really like this product, I do wish it would get a little bit tighter not allowing so much wiggle room at the top above the coupler level. But, it seems to be solid and serves the intended purpose.
Great product & great service. We ordered this lock for our 2018 Jayco Jay Feather travel trailer. After buying and returning similar locks at our local camper and automotive stores that did not fit, we turned to the internet and found etrailer.com. The website made it easy to shop. It showed the dimensions for this lock. We knew it would fit when we received it. We are extremely satisfied with the service and product we received. Thanks, etrailer!
I just purchased several items from etrailer. See photo for trailer lock and a new set of chains. I keep my trailer on the street and thought I had better start securing a little better. This hitch lock installed easily enough. I purchased three of them keyed alike for three different trailers, work trailer, camping trailer, and utility trailer. Super easy. This is my third purchase from etrailer over the years, and the customer support is out of this world. Actual people who call and email to follow up. etrailer sets the standard for what customer support should be.
Perfect fit for my older 1990's 26ft sailboat trailer - Solid lock - Easy to use - Nice addition to the "Tow Ready - Butterfly Lock" I also purchased from etrailer.com for the latch - Peace of mind is everything - 5 Stars on both locks
Awesome product.
Excellent product, fits the coupler on my Airstream trailer perfectly, very heavy strong secure lock.
I like how it is built and how nicely it fits on the coupler
Works great. This is my second one. Keyed alike for both of my trailers.
Fits my trailer and ordered one with same key as the one on my other trailer which is very handy. I suppose, with enough effort, this lock could be defeated but it presents a good reason to just move on to an unprotected trailer.
I bought several of these, keyed alike and have found them useful. The keyed alike feature is a winner. One key on every set of vehicle keys and I can access any of the rigs at will. The product itself can be a bit tricky to align, and on a steel hitch it will take some of the paint off eventually. Better than getting stolen I'd say. I've used it on 2 inch, 2&5/16 50mm and 1&7/8 couplers. The best fit is on the hitch I show a picture of, though in this case the lock is probably worth more than the trailer. . .
I have ordered 4 of these locks with all the same key number. They stay working great for years.
Exactly what I was looking for to secure my horse trailer! Extremely sturdy. Easy on and off with the key of course! Super fast shipping. Great price.
The ball lock I purchased from etrailer.com is the perfect tool for the job. It has several locking positions for different height tongue assemblies and one which was perfect for mine. The lock is smaller than the one I replaced, rendering it much less obtrusive. The chrome coloring also helps it blend better with the hitch, so if you use it while camping your trailer has a “friendlier” appearance to fellow campers. I really like the fact it came with 4 keys and case hardening makes it even safer and lighter than my old lock. Best of all, however, was the superb customer service I received from etrailer.com. Before, during, and yes, even after I received my lock they followed up to make sure I was happy. 5 star service. Would definitely recommend them to my trailering friends.
good product. Been using these for years. We have 12 bumper pull style trailers and use these tongue locks when they are on job sites. It's nice from e trailer because we can get the locks keyed the same. It was miserable having a bunch of different keys.
I've had it on the whole time so I can't say it will come off but has worked fine since I received it.
This coupler is very heavy duty and hopefully will deter any thieves.
Friendly people to deal with works hard to get you what you need good parts fast shipping
I just received this lock and have used it only once on a small, folding-type trailer. But, from everything that I can see, it looks to be very well made. The key/lock assembly appears to work well and I can’t imagine that it would be easy to defeat.
We have a larger, heavier trailer that we have yet to use it on. If my experience changes, I will update my review.
