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. .

Excellent lock for the trailer. Great service from the company and quick shipping. 777184
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. 774825
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. 752775
