Turnart Trailer Hitch Lock — Adjustable Heavy-Duty Coupler Lock (Yellow) Fits 1-7/8", 2" & 2-5/16"

Turnart Trailer Lock is an adjustable, heavy‑duty coupler lock that secures 1‑7/8", 2", and 2‑5/16" trailer tongues with bright, weather‑resistant protection.

If you haul trailers, a reliable hitch lock prevents unauthorized towing and adds visible theft deterrence. This Turnart model combines a ratchet‑style adjustment, robust steel components, and a corrosion‑resistant finish so it fits multiple coupler sizes and stands up to outdoor storage. It ships with three keys and a watertight dust cap to keep internal parts working smoothly through changing weather.

How does this lock fit different trailer coupler sizes?

The Turnart hitch lock uses an 11‑position ratchet adjustment that accommodates the most common coupler diameters without needing separate inserts. With the mechanism set, the lock secures the coupler latch and prevents the ball from seating. This design makes it fast to install and reduces the chance of selecting the wrong lock for your trailer.

• Adjustable ratchet with 11 locking positions for precise fit
• Compatible with 1‑7/8", 2", and 2‑5/16" couplers
• One lock fits multiple trailers — ideal for fleets or changing rigs

How tough is the construction against cutting and weather?

Turnart builds the lock from high‑strength steel and an aluminum body to balance durability and weight. The exterior receives a powder coat finish that resists corrosion and abrasion, while the included dust cap seals internal components against moisture and grit. Together these features make the lock suitable for long‑term outdoor use without frequent maintenance.

• High‑strength steel components for cut and shear resistance
• Aluminum body reduces weight while maintaining structural support
• Powder coat finish and watertight dust cap for weather protection

What visibility and convenience features does it offer?

The bright yellow finish serves as a clear visual deterrent, signaling that the trailer is secured and discouraging opportunistic thieves. The package includes three keyed duplicates so you can distribute spares to co‑workers or keep a backup at home. Installation and removal are straightforward without extra tools, saving time when hitching and unhitching.

• High‑visibility yellow reduces theft risk by drawing attention
• Three keys included for convenience and backup access
• Tool‑free installation with quick ratchet adjustment
