The CURT QuickPin trailer coupler is a revolutionary coupler design, doing away with the traditional latch mechanism for simple, stress-free trailer hookup. Most couplers use a complicated hinging latch that's prone to wear out and become corroded, leading to difficulties and frustration. Instead of a latch, QuickPin uses a simple hitch pin to create a safe, reliable, hassle-free towing connection. It's as easy as dropping the trailer tongue onto the hitch ball, inserting the QuickPin hitch pin, and that's it! No more wrestling with a rusty latch, and no adjustment or tightening needed. This trailer hitch coupler is fully tested according to SAE J684 specifications. It is rated for 3,500 pounds and fits any standard 2-inch diameter trailer ball. The coupler channel can be mounted on a 2-1/2-inch wide trailer tongue beam, featuring standard mounting holes to fit most existing bolt patterns (mounting hardware not included). It is also finished in a durable black powder coating for lasting rust resistance. NOTE: This coupler comes with a 1/2-inch pin that must be used when connecting the trailer. It may not be replaced with a different 1/2-inch pin.
