Couplers add security to your towing setup. They’re mechanisms that attach the tongue of the trailer to the vehicle’s hitch ball. This is to ensure a secure connection between the two for safe towing. There are a few different types of coupler locks, including bulldog, A-frame, and straight tongue couplers. Bulldog couplers are heavy-duty and usually designed for bulkier trailers. A-frame couplers are most commonly used on utility trailers. Straight-tongue couplers are designated mostly for lighter trailers, such as boat trailers. They all come with a latch or lock system to securely fasten them to the hitch ball. This trailer hitch accessory prevents disconnection and ensures safe towing, allowing for carefree travel.
