Dexter 2 Ball Coupler Lock Plate, Part Number 074-339-00, Trailer Coupler Locking Plate

The Dexter 2 Ball Coupler Lock Plate, part number 074-339-00, is a replacement locking plate for Dexter 2 ball trailer couplers. This plate is the component inside the coupler body that engages the trailer ball and secures the coupler in the locked position, keeping the trailer connected to the tow vehicle during transport. As a genuine Dexter part, it is manufactured to match the fit and function of the original plate it replaces, making it a straightforward swap when a coupler's lock plate is worn, bent, or no longer securing properly.

This lock plate is sized specifically for 2 ball couplers, so it should be matched to a coupler built for that ball size rather than used on a 2-5/16 inch or 1-7/8 inch coupler. Replacing a worn lock plate restores proper clamping engagement on the trailer ball, which is important for keeping the coupler latched securely while towing.
