.I’m sure this is a common sense question but I can’t seem to find anything online. How do a lock the trailer coupler to the receiver hitch ball on an 88 bass cat Pantera trailer? There is a hole that says lock on it but it does seem to keep you from releasing the coupler. I’ve usually used a standard coupler and just put a bolt or lock through the top latch piece. Can anyone point me in the direction for the correct lock to keep the coupler from malfunctioning when hauling.
