Are you in the market for a reliable towing coupler? Look no further than the Posi-Lock Straight-Tongue Coupler! This heavy-duty coupler is perfect for those who need a sturdy and secure connection for their trailers with parts easily available for repair.

Why Choose the Posi-Lock Straight-Tongue Coupler?

The Posi-Lock Straight-Tongue Coupler boasts a gross towing weight capacity of 5,000 lbs, making it ideal for heavy-duty towing. Its steel construction ensures it's corrosion-resistant, tear-resistant, and wear-resistant, so you can trust it to last. Plus, the zinc plating adds an extra layer of protection against the elements.

Installation and Compatibility

Installing the Posi-Lock Straight-Tongue Coupler is a breeze. It bolts onto trailer tongues and attaches securely to trailer hitch balls with a locking latch mechanism. However, keep in mind that it's only compatible with 2-inch ball and pin hole diameters, so double-check your trailer's specifications before purchasing.
