## Overview

The CURT 23518 Black Trailer Hitch Lock features a robust 5/8-inch diameter pin designed to fit standard 2-inch receiver tubes. Crafted from high-strength steel with a durable powder coat finish, it offers superior theft deterrence and corrosion resistance. Its barbell-style design uses a simple 1/4-turn key lock mechanism for quick, secure operation, and includes a watertight dust cap to protect internal components. Two keys come standard, making it a reliable, versatile security upgrade for your towing 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: Perfect replacement pin for a detachable towbar. - Purchased this as a replacement for the chrome pin on a new VW Amarok. Secure, unnoticable and no doubt just as strong as the original for just north of £20. Its finished in black all around and should last way beyond the life of the vehicle. Perfect.
Review: Great product. - I purchased this product to replace the stock silver pin/R clip design that came with my factory fitted receiver tow bar. I needed something with greater security, as I have a hitch lock for the trailer, but nothing to stop anyone from removing the tow ball from the bar. The added bonus is it's much neater and cleaner looking.

### ⭐⭐⭐⭐⭐ Great product.

### ⭐⭐⭐⭐ Decent quality and works
*by N***L on 21 July 2025*

Works as intended but wish it would lock on without the key , as it’s a bit fiddly with key , bent down trying to put on and lock, if it snapped on and locked and use the key to unlock this would be perfect
