## Description

Master Lock Trailer Lock, Stainless Steel Adjustable Coupler Latch Lock, 2847DAT.

Review: Convenient Trailer Lock for Stress-Free Travels - 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.
Review: Reliable Locks That Require Proper Maintenance - I've been using these locks for years, and they truly perform well as long as you remember to keep them lubricated. In my experience, regular lubrication is key, especially if you encounter harsh winter conditions with salted roads. I usually purchase these locks in a set along with the coupler insert lock. However, I must admit that I sometimes forget to remove the bar lock from the trailer frame or tool box, leading to occasional replacements. Despite this minor inconvenience, I highly recommend these locks for their durability and effectiveness. Just remember to give them some care with a good spray oil 3-4 times a year to keep them in top condition.

### ⭐⭐⭐⭐ Serves the purpose
*by P***M on April 10, 2025*

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.
