Constructed from high-strength steel and finished in black powder coat, the CURT 23518 combines simple operation with weather protection: a 1\/4-turn keyed lock mechanism and a watertight dust cap guard internal components from corrosion and debris. Note that the usable pin length is 2.85\" and it is not compatible with double-walled receiver tubes.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the CURT 23518 prevent trailer or ball mount theft?\u003c\/h3\u003e\n\u003cp\u003eThis hitch lock replaces a conventional hitch pin by locking into the receiver’s fastener hole, making removal of the ball mount difficult without the correct key.
