CURT Straight Tongue Coupler with Posi-Lock

Part Number: 25128



Selecting the right trailer hitch, ball mount and trailer ball to manage the weight of your trailer is not the only important aspect of towing; you also need a trailer that can stand up to the road ahead. That means equipping it with a coupler that is built to go the distance.

CURT straight-tongue couplers, featuring the Posi-Lock latch, are the most common type of trailer coupler. With a mounting channel designed to fit onto a straight trailer tongue, the Posi-Lock coupler is easy to install. It is made from hardy steel construction and has a durable zinc finish to protect from corrosion, wear and tear. The lockable latch mechanism is easy to operate and adjusts by tightening or loosening a simple bolt.

Spring and nut posi-lock mechanism allows for easy adjustment. Features holes to accept a safety pin or coupler lock. Constructed from die-cut, punched out steel. Protected by a durable zinc-plated finish.
