# CURT 23501 Trailer Hitch Lock, 1/2-Inch Pin for 1-1/4-Inch Receivers

Receivers: The CURT 23501 trailer hitch lock is a keyed barbell-style pin designed for a 1-1/4-inch receiver with a 1/2-inch pin hole. Its quarter-turn operation, dust cap and two included keys suit owners looking to secure a compatible ball mount or hitch accessory, though customer feedback raises fit concerns worth checking against the receiver and mount dimensions.

## Less suited to

## Customer feedback

That concern matters because the listing's nominal fit depends on a 1/2-inch hole and suitable clearance.
