Hey Anthony!
I really like the Trimax Dual Purpose Coupler Lock and U-Lock for 1-7/8", 2", and 2-5/16" Couplers # TMX67FR because it can fit a variety of coupler styles and sies, plus it has the matte-looking finish on it which makes it look more intimidating than other coupler locks with this same style.
While we all know that looks aren't everything, if the trailer next to yours has a weaker looking lock then odds are a would-be thief is going after that trailer first.
