CZC AUTO Trailer Lock Quarter-Inch Diameter, 3-3/8-Inch Span — Latch-Type Coupler Lock with Keys

Overview

Designed for everyday towing scenarios, the CZC AUTO Trailer Lock provides a compact safeguard for latch-type couplers. The lock features a quarter-inch diameter pin and supports up to a 3-3/8 inch span, making it compatible with many standard trailer hitches. This isn’t a guaranteed theft deterrent, but it offers a tangible deterrent when you need to park, dock, or tow.

Built for real-world use, the dogbone-style hitch lock combines ease of use with solid materials. The 360-degree rotating head turns smoothly, and a quarter-turn can secure the coupler while you verify the lock. When you’re ready to unlock, turning the key releases the pin with a quick pop for fast connection or removal.

Durable design

The body is crafted from carbon steel for strength and twist resistance. A black electrophoretic coating helps resist rust in everyday conditions. Inside, a zinc alloy tubular core and a solid key add security and compatibility with the locking mechanism.

Weather-ready protection

The lock is equipped with a watertight rubber cap that shields the core from rain, snow, ice, and dirt. The cap remains in place between uses, helping maintain smooth operation in challenging conditions.

Two keys and practical use

Two keys are included so you can keep a spare in a safe location. The design supports quick locking and unlocking, which can save time during busy travel days. The cap design also helps seal out the elements during transport and storage.

How to use

• Align the pin with the coupler, rotate the head counterclockwise about a quarter turn to secure.
• Gently pull on the lock head to confirm it is engaged before towing or parking.

Notes and warranty

• Verify the dimension and pin length before purchasing for best compatibility.
• Includes a 30-day money-back guarantee and a 12-month warranty. For any issue, contact us and you’ll receive a response within 24 hours.
