Master Lock Adjustable Coupler Lock Stainless Steel Trailer Hitch 2847DAT

Used to lock my square drop camper trailer. Works as should.

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.

This item is not to stop a thief but it should keep the coupler from opening unexpectedly. There are many heavy duty locks that will stop theft but the shaft on this has a small diameter so it fits into the coupler holes. I used a saw and a file to shorten and smooth the shaft so that I don't hurt myself on the protruding end or bend it which would make it hard to remove.

I bought this coupler lock for my small utility trailer that i use for hauling design gear to client shoots. It slips over the latch easily and I like the 6 positions since my old latch is a bit chewed up from years of use. The stainless finish looks good and hasn’t rusted yet after a few rainy weekends in the driveway. I can lock and unlock it one-handed while holding a camera case in tge other, which is exactly what i needed. My only gripe, the keys feel a little thin and cheap, so I’m babying them and keeping a spare on my desk in the studio.

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.

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

Great

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.
