RETRUE Trailer Hitch Coupler Lock, Widened Universal Fit (2-5/16in), Heavy-Duty A36 Steel, Gray

If you tow trailers, boats, or utility gear, a coupler lock that actually fits irregular or larger hitches is essential. This widened U-shaped design from RETRUE uses thicker A36 steel and aluminum-alloy components to resist cutting, prying, and corrosion while offering adjustable locking positions so one lock works across common coupler diameters.

How does this lock adapt to different coupler sizes?

The RETRUE lock includes an expanded U-shaped shackle and eleven distinct locking positions so you can set the depth to match your coupler diameter. That makes it compatible with 1-7/8", 2", and especially 2-5/16" couplers where standard locks often fail.

• Widened U-shape fits irregular or oversized hitch heads.
• 11 adjustable locking slots for precise fitment.
• Works across common coupler standards without adapters.

What protects the lock from cutting, prying and weather?

The lock body combines A36 steel with aluminum alloy materials to balance strength and corrosion resistance. Rustproof finishes plus a rubber dust cap on the cylinder keep moisture and grit out, extending service life in outdoor conditions.

• Thicker steel shackle resists bolt cutters and leverage attacks.
• Aluminum-alloy components reduce corrosion risk.
• Rubber cap prevents water and debris from entering the cylinder.

Is the locking mechanism secure and easy to use?

RETRUE upgraded the cylinder to a heavier-duty design with reinforced keys to improve pick resistance and durability. Operation is straightforward: align the shackle to one of the eleven slots, insert the key, and lock—no special tools required.

• Thicker keys designed for longevity and reliability.
• Enhanced cylinder reduces vulnerability to picking.
• User-friendly single-key locking and release action.

What support and warranty come with the lock?

Every RETRUE coupler lock includes a 120-day satisfaction warranty and access to 24/7 customer support for questions or assistance. If fitment or performance concerns arise, the vendor encourages contacting support directly for quick resolution.

• 120-day warranty for peace of mind.
• Round-the-clock customer support via the Ask a Question option.
• QC-checked before shipping to ensure functionality out of the box.

Who this is for: The RETRUE Universal Trailer Hitch Coupler Lock is aimed at trailer owners, boaters, landscapers, and fleet operators who need a robust, weather-resistant lock that accommodates larger or nonstandard coupler heads. If you need a single, hard-wearing lock to secure multiple trailers or to protect a high-value load, this widened-design coupler lock is a practical choice.
