CURT 25470 QuickPin No-Latch Trailer Coupler for 2-Inch Hitch Ball, 2-in Channel, 3,500 lbs

  • ONE-PIN COUPLING. QuickPin is an innovative trailer coupler engineered to provide fast, hassle-free coupling with just one pin. It hooks up to your ball hitch simply by inserting the included 1/2-inch pin (included pin must be used, no replacements).
  • NO LATCH. QuickPin is far easier to use than traditional trailer tongue couplers because it doesn't use a latch. No more jamming, frustration or complicated hinging components prone to wear out.
  • NO ADJUSTING. QuickPin also doesn't require adjustments or tightening like traditional latch-style trailer couplers. Just drop the trailer tongue onto the hitch ball, insert the provided pin, and that's it.
  • SECURE CONNECTION. This trailer hitch coupler can be mounted onto virtually any 2-inch wide trailer tongue beam, and it accepts a standard 2-inch diameter trailer ball (trailer mounting hardware not included).
  • THOROUGHLY TESTED. Tested to SAE J684 specs and rated for 3,500 pounds gross trailer weight, this trailer coupler ensures a safe, reliable towing connection.
