Review on 🔒 AutoEC 5/8 Inch Trailer Hitch Locking Pin, Durable Harden Steel Tow Receiver Hitch Lock with Safety Clips & Anti-Rattle O-Rings, Compatible with Class III IV V Hitches, 2 Inch & 2.5 Inch Receivers, 2 Pack (Black) by Jason Olguin

So without the packaging it looks like a good device. It looks like it's well built. I have a 2 1/2" receiver on my pickup and it fits without the rings. With this one (opposite end of the lock) you can't push it deep enough for the pin to go in its hole. So weather protection? Like all of these "Lock" picks, the lock becomes a problem over time, weather, and humidity. I live in a four-season state and my streets are salted during the snow season. High humidity in spring and summer. Let's see if the lock withstands the weather otherwise seems a good unit I will let you know if there are any problems
