M**Z
Built for a standard Bulldog coupler, did not fit mine as intended
Well built piece. Heavy and solid materials. Oddly enough the lock is aluminum bodied with a steel cylinder and pin.I measured my coupler and purchased according to the listing instructions.Come to find out the upper half would not install onto my coupler. It turns out my coupler was too “thick” to fit between the locks’ bottom plate and the mid plate on the upper half.Oddly enough, it will install “backwards” on my coupler, but is not as secure as it would be if installed “correctly”. It still works, but not as ideal as it could be.
