Great Color, No Rust, Theft Deterent
Great fit and finish that blends in well with our tow hitches. No signs of rust or fading from being outside all the time. The rubber cap can go missing fairly easy if you're not careful. These types of locks aren't unbreakable, but it does help deter theft, because rather than removing a pin without any tools and taking your hitch, a thief would at least have to commit to breaking the pin. A step many wouldn't bother doing especially in a public space. Cheap, easy to use peace of mind.

Sleek and Secure Trailer Lock
Solid construction; offers both heavy duty security, while remaining slim and less bulky. Easy to lock and unlock. Blends into the rest of my trailer hitch so that it calls less attention to the area. Waterproof cap seems easy to secure, so expect less rust over time.

Good purchase
Great product! The weight is nice, the color, and paint are quality. Comes with 2 keys. The cap over the key hole seems a bit flimsy but i will report back to inform how long it holds up.

Lock that hitch cover now.
Tidy build, cap protecting key slot is a nice touch. Was quite easy to install and lock my hitch cover. Very secure and quiet, no rattling noted. Like they add a small silicon ring to hold the keys together and then add a key ring on top.

Fits - 2021 RAM TRX
This fits the 2021 RAM TRX perfectly. Lock seems to work, secure, definitely need 2 hands to open it, very tight fit. I lubed it up with silicone spray inside and out after a test fit, so hopefully it will be protected from corrosion and salt. Per most of these style hitch locks, the rubber cap seems loose. Black on black is a nice color match for it to blend in visually. We'll see how it lasts, hopefully over 2 years.

Too short for My Prado. I had to grind the ends smaller to get the length.

Arrived in clear sealed bag, without keys. One of the zip ties was replaced with a twist tie. Edit: Replacement was shipped and it arrived complete. A great locking pin for our hitch. Works well. Dust cap keeps the keyway clean.
