METOWARE Lunette Eye Lock for 2-1/2"–3" Trailer Rings — Heavy-Duty Steel, Weather-Resistant Yellow Coating

METOWARE Lunette Eye Lock is a heavy-duty steel tow ring lock designed to fit standard 2-1/2" to 3" lunette trailer rings and deter theft while resisting rust and weather.

If you haul equipment, boats, or trailers with a lunette eye and pintle hitch, securing the tow connection is one of the most effective ways to prevent unauthorized towing. The METOWARE Lunette Eye Lock combines a robust steel body, weather-resistant yellow coating, and a simple install/remove design so you can lock your trailer quickly and dependably. It accepts most 1/2" padlocks (padlock not included) and measures approximately 5" x 5" to cover the ring opening fully.

How does this lock stop someone from towing my trailer?

The lock physically blocks the lunette ring opening so a hitch cannot couple to the trailer. Its heavy-duty steel construction resists bending and prying attempts, and the acceptance of a 1/2" padlock lets you complete a secure closure that requires tools or force to defeat.

• Fits standard 2-1/2" to 3" lunette trailer rings snugly.
• Solid steel body built to resist breakage and prying.
• Accepts a 1/2" padlock to complete the theft-deterrent system.
• Compact 5" x 5" footprint covers ring opening effectively.

Will it stand up to weather and corrosion?

Yes — the lock’s yellow coating reduces corrosion and helps prevent rust from daily exposure. That protective finish plus the heavy steel core extends useful life even when the lock stays mounted outdoors on trailers, boats, or RVs.

• Yellow corrosion-resistant coating for outdoor durability.
• Heavy-duty steel construction underneath the finish.
• Suitable for exposed installations on boats and RV trailers.

Is it easy to install and compatible with my trailer?

Installation is straightforward: the lock slides into the lunette eye and secures with your padlock. It’s purpose-built for lunette rings and works with the common 2-1/2"–3" size range used on many equipment, utility, and military-style trailers.

• Simple slide-in design — no tools required for normal use.
• Designed specifically for lunette ring hitches, not couplers.
• Compact dimensions (about 5" x 5") for universal coverage of the ring opening.

What padlock should I use with the METOWARE Lunette Lock?

Choose a robust, weatherproof 1/2" shackle padlock rated for outdoor use to maximize security. A laminated or stainless steel padlock with a closed shackle profile will resist cutting and corrosion better than a basic indoor lock.

• Use a 1/2" shackle padlock (not included) for proper fitment.
• Pick a weatherproof, cut-resistant padlock for best protection.
• Consider keyed-alike or high-security padlocks depending on your fleet needs.

Who is this for? The METOWARE Lunette Eye Lock is aimed at trailer owners, equipment renters, boaters, and fleet managers who use lunette ring and pintle hitch setups and want a compact, heavy-duty deterrent against theft. If you need a straightforward, durable solution that fits standard 2-1/2"–3" lunette rings and accepts a 1/2" padlock, this lock provides practical protection without complex installation.
