Awesome product.
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
I like how it is built and how nicely it fits on the coupler
Excellent product, fits the coupler on my Airstream trailer perfectly, very heavy strong secure lock.
Works great. This is my second one. Keyed alike for both of my trailers.
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.
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.
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.
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.
Feels solid - should work well.
Bought several items in the past and they always deliver fast and accurate!
Looks really nice and secure. Will see hoe long it lasts.
I still have my trailer so I'm guessing the lock works.
I have not installed the lock on the trailer yet! My trailer is available! From what I can see the lock looks very strong and easy to use! I'm sure looking forward to using the lock! It should provide excellent security!
