Demo-master-lock-locks-2847dat Today were doing a review of the Master Lock Adjustable Trailer Lock part number 2837 DAT. This lock comes with all stainless steel parts to prevent rust and corrosion. The pin has a built in notches to walk around the barrel lock. The pin diameter is a quarter inch. It will fit the 5/8 standard couplers and from one inch to 2-5/16 ball couplers. The lock works like this; simple take our pin, run it through our coupler latch and we will take the barrel lock and slide it on.
Well lock it into position, remove one of our two keys and put our cover over the barrel lock. And there you have it for the Stainless Steel Master Lock Adjustable Trailer Coupler lock part number 2847 DAT.

Very pleased tough and looks almost impossible to remove without key.
I purchased this lock for a way to keep people honest while my trailer was attached to my truck . Knowing the lock is cheap and Master Lock brand, disappointingly the lock itself traps moisture inside even with the cap closed and facing downwards - a bit of silicone around the cap would help. Because of the moisture, it’s has corroded a bit inside making the key almost impossible to insert. I’ve had to soak the lock with WD40 to help the key go in. It still mostly works but I wouldn’t recommend it. The problem is there’s not many cheap alternatives to lock the latch while your trailer is attached to your vehicle. Skip this and find another option.
Great little item does the job. If I had one issue. The key gets stiff to turn I'm not sure if it's going to jam at some point which is a shame because I really like it.
Product is just as described and very reasonable in price. Shipping was also very quick. Thanks!
Called to order another lock because I liked the one so much I had gotten earlier in the week. Customer Service was awesome. Information was gathered by the rep. that helped me with my decision. I'll come back again for all of my trailer needs.
Great lock
Better than nothing . Should slow down the bad guys if they want to try & steal the trailer . They better be faster than the 9MM !
Excellent deterrent for thieves. Works on a multitude of trailers.
Works well for what it is, keeps tongue engaged and provides minor deterrence to thieves, adjustable rungs allow for many widths and configurations to secure tongue lock. I use one on all my trailers which are all a bit different. This one is adaptable.
stainless and easy to use
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
great lock
I usually store my Anderson hitch drawbar in the coupler. I had a Bulldog installed on my Airstream (well worth the $500 it cost). I use this lock when among friends to prevent them from dropping the Anderson on a foot if they are curious about the Bulldog. This lock would not deter a thief.
Went the extra mile to find what I need ed!
The 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.
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!
As usual when dealing with etrailer, everything came in as advertised! Great people to deal with!
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.
Johnathon 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.
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 lock
Love this product. The stainless steel is a key feature (no pun intended)

Still kicking
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.
