Trailer Couplers and Locks
When looking for a trailer coupler you need to know what trailer tongue you have in order to get the right one. Do you have a straight tongue, A-frame, round tongue or gooseneck coupler?
Your trailer coupler is either going to be bolted or welded at the end. After you determined the coupler, next you need to look for is the GTW (Gross Trailer Weight). A trailers coupler must be equal to or greater than the gross trailer weight.
Coupler capacities range from 2,000lbs to 30,000lbs, depending on style. You should always protect your investment by purchasing coupler locking mechanism.
