## Overview

The CURT 23518 Black Trailer Hitch Lock features a robust 5/8-inch diameter pin designed to fit 2-inch receiver tubes, providing theft deterrence with its high-strength steel barbell design. Its simple 1/4-turn locking mechanism ensures quick and secure operation, while the included watertight dust cap and powder-coated finish protect against corrosion. With two keys included, this lock offers reliable, weather-resistant security for your trailer setup.

## Description

Make your tow vehicle and trailer more secure by keeping them locked up tight with a CURT hitch lock. Like a hitch pin and clip, a hitch lock is designed to insert into the fastener hole in the side of a receiver tube in order to hold a ball mount or hitch-mounted accessory in place. While a CURT hitch pin does offer sufficient strength for keeping your ball mount firmly attached, a CURT hitch lock goes one step further. CURT hitch locks allow you to lock your ball mount into your trailer hitch, deterring theft and preventing anyone from detaching your trailer at the ball mount and towing away your property without your permission. This CURT hitch lock features a barbell design and comes with a 5/8" pin diameter to fit a 2" receiver tube size (usable pin length is 2.850"; will not work with double-walled receiver tubes). CURT barbell hitch locks are comprised of a pin with two end caps and a round locking mechanism. They are key-operated and activate with a simple 1/4-turn. They also come with a watertight dust cap to keep out the elements and prevent corrosion. For the ultimate in towing security, a hitch lock and coupler lock used together will provide security at both the vehicle-side and trailer-side of your towing setup. For your boat, ATV or camper, keep your toys more secure with CURT hitch locks.

Review: Great Color, No Rust, Theft Deterent - Great fit and finish that blends in well with our tow hitches. No signs of rust or fading from being outside all the time. The rubber cap can go missing fairly easy if you're not careful. These types of locks aren't unbreakable, but it does help deter theft, because rather than removing a pin without any tools and taking your hitch, a thief would at least have to commit to breaking the pin. A step many wouldn't bother doing especially in a public space. Cheap, easy to use peace of mind.
Review: Great. - Great.
