Adjustable Coupler Lock Stainless Steel Trailer Hitch 2847DAT | Keyed trailer hitch helps secure RVs, trailers & towing gear, fits coupler latch widths up to 2-3/4 inch, 6 locking positions

Waiting to test it out during my next trip. i like that it’s made of stainless steel, so it feels sturdy and reliable. easy to adjust and fits well on my trailer coupler. it’s a simple add-on but gives me more confidence when i leave my trailer parked.

We were renting a uHaul for a week trip and I wanted to secure the trailer so I could disconnect and leave while we were out and about. This was a low cost, great solution. Gave me peace of mind that it would deter theft and was easy to use. Only potential issue is you can tell it is low cost, the keys are kinda like the daughters first diary level quality (not robust) and I'm not sure I'd trust it to stay outdoors in the elements long term as it'd probably rust. Overall: This is great for occasional use but I'd personally upgrade to something better if I was using it on my own trailer long term.

This coupler lock serves the purpose. We've used one for years and just bought several more for a different trailers. I like that it has a little top that covers the key hole, so it protects it. After several years, it does get aggravating as the key won't turn smoothly in it anymore. With the price, you can afford to replace it after a few years. It's well made and easy to use.

Works great. Used when park trailer overnight and leave attached to vehicle.

If you're looking for a compatible hitch lock that will go on your 1up USA bike rack that will install on a Tesla Model Y with the factory tow package, this is it!! Quality is great and fits perfectly in the tight space. It's somewhat easy to use once you get a hang of it, you pretty much lock it in each one of the dashed positions Like I said it's the perfect companion for the 1UP bike rack with a 2-in hitch!!

Works no issues

Securing our rented uHaul trailer for our week-long trip was a top priority for me. I needed something reliable that would allow me to disconnect without worries while we explored our destinations. The trailer lock I found was not only affordable but also incredibly effective. It provided me with the peace of mind I needed, knowing that our belongings were safe from potential theft. Additionally, its user-friendly design made it a breeze to use, adding convenience to our travel experience. Highly recommend this product for anyone looking for a simple yet efficient solution to safeguard their trailer during trips.

They work for Bulldog Hitch but only been using a month and the locking & unlocking is challenging. Have to work with it and wiggle it around to get it to lock or unlock.

Muy práctico y resistente a la interperie, este candado lo adquirí para reponer uno va idéntico que use durante más de 10 años el cual nunca se trabó y siempre funcionó bien el cual se me me extravió y me peso, probé otros dos modelos distintos de otras marcas pero este es para mi el más práctico y seguro de uso

I was looking for a lock that can lock my trailer, I asked a question if the lock is 6mm, after waiting for one week, no one answered, so I have to take a leap & buy it, unfortunately its 7mm plus, had to return it. I had added two pictures, with 2x measurements from different places, both have different readings, my calliper is lab calibrated by a calibration company, so its 100% correct. The whole specification includes every thing, but the most crucial part was missing, picture attached for those who are looking for such info, it would have been appreciated, if seller had responded to the question.

Small form factor and does what I need it to do. Feels securely attached. I left it locked on my SUV hitch for a couple of days to see if it would fall off - it didn't. Will paint it black so it blends in with the hitch on my SUV. The lock is fluid and operates well. I used this to secure a Superman hitch cover.

Super pratique

Am Anfang skeptisch, aber super leicht. Sicher. Persönlich würde ich es weiterempfehlen.
