Review: Handy trailer lock for peace of mind - 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.
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.
