DESCRIPTION

[UPGRADED ALL-WEATHER PROTECTION] We’ve enhanced our classic design with an integrated rubber lock cylinder cap. This watertight seal prevents rain, snow, and road grit from entering the keyhole, ensuring smooth, jam-free operation even in the harshest winter or coastal environments.

[PRECISION 1/4" LATCH FITMENT] Engineered for a perfect fit on standard trailer couplers. With a 1/4-inch diameter pin and a 3/4-inch effective span, this lock secures your coupler latch handle to prevent accidental unhitching or unauthorized removal during transit and storage.

[DUAL-LAYER CORROSION DEFENSE] Built to survive the elements. The lock body features a premium black painted finish, while the pin is shielded with durable zinc plating. This dual-defense system is specifically designed to resist rust from salt air, humidity, and road de-icers.

[HEAVY-DUTY ZINC ALLOY STRENGTH] Don’t be fooled by its compact size. Forged from high-strength zinc alloy, the RETRUE coupler lock provides robust resistance against prying and cutting, acting as a critical deterrent for boat trailers, RVs, and utility haulers.

[DUAL KEYS & QUICK OPERATION] Each RETRUE latch lock includes 2 high-durability keys for your convenience. Keep one on your truck's keychain and the other as a backup in your glove box, ensuring you’re always prepared for the road.

Technical Specifications

Industrial Strength for the Marine & Towing Professional
When you’re hauling a boat or an RV, the smallest component can be the most critical. An unlocked or unsecured latch is a liability. The RETRUE 1/4" Coupler Pin Lock provides the industrial-strength security needed to keep your trailer safely connected to your truck, whether you’re at a busy boat ramp or a highway rest stop.

Designed for Coastal & Salt-Belt Drivers
Standard hitch locks often seize up due to internal corrosion. We’ve specifically engineered the RETRUE Upgraded Model to solve this. By combining a zinc-plated pin with a protective rubber cap, we’ve created a lock that won't seize in freezing temperatures or rust in salt-heavy coastal air. It’s the essential gear for any Jet Ski, boat, or small equipment trailer.

Quick, Simple, and Effective Theft Deterrence
The RETRUE Latch Lock is designed for effortless daily use. Its low-profile design acts as a powerful visual and physical deterrent, signaling to "quick-grab" thieves that your rig is a hard target. It eliminates vibration-induced unlatching on the highway, ensuring your trailer stays hitched until you choose to unlock it.
