Today on our trailers, we're going to take a look at the Master Lock adjustable trailer coupler lock, part number 2847DAT. Let's go ahead and see what it looks like on our trailer. Here we have our stainless steel lock rod and tumbler. As you can see, the tumbler is in a nice rubber-coated housing. We open the cap on it and we can open up the key and tumbler inside. What's really nice about it having a cap is it's going to help keep out that dirt, dust, debris, and especially moisture and will prevent corrosion over time. Provided with the lock is also two keys. We can take the key, rotate the tumbler, and remove the lock rod.
As you can see, the lock rod has multiple locking points for different sizes and styles of trailer coupler latches. For this one, we can go ahead and take the lock rod, feed it through the latch, pushing it up tight against the latch, and then take the key and tumbler, slide it on, rotate it, remove the key, put our cap back on. Now our tumbler is locked to the rod, and the latch on our coupler is locked. If it was already on our vehicle and locked to the trailer ball, it couldn't be removed, adding security to our trailer from theft. Now, to remove our lock, we simply take our key into the tumbler, rotating it so we can slide the lock rod out, and we're ready to unlock our trailer and load it up on our vehicle. There you have it for the install, operation, and review of the Master Lock adjustable trailer coupler lock, part number 2847DAT. .

It bends because its thin at each locking point
Sierra K - 12/16/2021Love this product. The stainless steel is a key feature (no pun intended)
Jimmy W - 06/17/2021Johnathon was my sales rep that I dealt with when I had questions. He was great and he kept track of my order and when the trailer hitch was not available from the manufacturer until late March, he helped me choose another one and sent it to me with the freight free of charge. It took only two days to arrive and I am very happy with the hitch and wiring harness. Highly recommend.
Ordered product for my Tab Travel Trailer and it turned out I ordered the wrong item They gladly refunded the mistake and sent my the right one. I had called and they guided me to the correct product. Very happy...vann
vann a - 03/16/2018The lock worked very well. It fit perfectly into the existing hitch pin hole. The variable length on the lock shaft allowed me to snug up the lock to the hitch mechanism which I think will make it more difficult for any thief to cut or remove the lock. The key operation was simple and easy. I use the lock pin when my trailer is attached to my vehicle and also when it is not attached so as to serve as a secondary trailer coupler lock and not allow the coupler to be opened for thieves to insert their ball hitch and steal the trailer and boat. Great product.
Great product. Fits my 2010 Wrangler perfectly. etrailer was the best to deal with. Very personable and quick shipping. Great company.
I placed the order on a Saturday and it was filled on Sunday, the next day!! I received the order today - Wednesday via UPS. I wish everyone took the same responsibility to provide the utmost in customer service as E-trailer has. When I need any further trailer parts they will be my first and only location I will order from!! Ron
Easy ordering process! Fast shipping! Product as described. Installed easily and seems to be a quality product . Feels very solid. Installed on my gearspace 34 cargo carrier. Great price!
I purchased a pin type trailer coupler lock and a ball type coupler lock. Both work well and were easy to install. Of the many products available from etrailer, it was easy to find what I needed. It was shipped the same day as ordered and arrived quickly. As a first time customer, I am very pleased with the results. I will shop at etrailer.com for future needs and wants. As a matter of fact, I had a product question quickly answered by etrailer experts and ordered the suggested item today. I give etrailer 5 1/2 stars!
I don't rate this product very high since the Master Lock assembly is poorly built. I believe it would not take a thief long to break the lock and just pull the pin out. The lock is even hard to operate with the key. Not recommended I am using this product with the coupler lock I purchased. I am thinking if its worth the hassle to send it back.
I believe it will be functional as it is advertised, but I does not appear to be as well build as most Master Lock products have purchase before. I does fit my trailer hitch that is was ordered for.
Great product at a low price
Jimmy - 01/28/2021Still working smoothly after a year of use, on both trailers...
Excellent lock for the trailer. Great service from the company and quick shipping.
Had to drill out the whole in the trailer latch to make this product fit It is exactly what I wanted. Now my trailer is safe from theft and uncoupling.
Does exactly what I bought it for. The pin is long enough to go through the hitch and ensures that it doesn't wiggle loose. This gives me peace of mind, and is more secure than a bolt with a nut on it.
This is the second of three security devices we bought last year. It's been everywhere with us from the local beach to northern Vermont. Sturdy and reliable.
Lost the lock portion of the one I had before. Always go straight to trailer.com for anything I need! Great service, got the item in a week.
Perfect to replace a lock on Let's Go Aero Gearwagon
Was a bit skeptical at first on how buff this would be but after seeing it in person very solid. Fits my 1 inch lock perfect.
Hitch lock works great. I wish it could have been keyed the same as my receiver lock pin...but that wasn't an option.
Although it will only keep the honest folks honest, it gives me a little more piece of mind having this securing the tongue latch on my trailer.
Great fast service!! Knowledgeable staff! Will keep buying from ETrailer.com
High quality
