Antivanl Trailer Hitch Lock — Aluminium Ball & Tongue Lock for 2" to 2-5/16" Couplers, Hardened Steel Rod

If you leave a trailer, camper, or utility cart unattended, securing the coupler is one of the most effective ways to prevent theft. The Antivanl Trailer Hitch Lock combines a lightweight aircraft-grade aluminium body with a hardened steel locking rod and a three-position pin layout, creating a visible, sturdy barrier that keeps casual thieves and opportunistic lifts at bay.

How does this hitch lock stop thieves from taking my trailer?

By covering the ball coupler and locking into place, the Antivanl unit prevents a tow vehicle from sitting on the hitch and towing the trailer away. Its solid construction resists common tampering methods and the exposed, unmistakable appearance acts as a deterrent before thieves try force.

• Wraps over the coupler to block hitch attachment
• Hardened steel rod resists cutting and leverage
• Aircraft aluminium body reduces rust risk while staying strong
• Highly visible design discourages opportunistic theft

Will this lock fit my trailer’s coupler?

The Antivanl lock is made to cover standard round couplers and accommodates both 2" and 2-5/16" ball sizes. Its three-pin placement layout offers flexibility to match the typical hole positions on many coupler brands, making it compatible with a wide variety of trailers.

• Fits over 2" and 2-5/16" ball couplers
• Three pin positions adapt to different coupler hole patterns
• Compatible with most common coupler types and brands
• Single-pack solution for one trailer or spare use

How easy is it to install and remove day-to-day?

Installation requires no special tools: insert the convex section into the coupler, slide the locking rod through the matched pin hole, then secure it with the lock. Removal is simply the reverse—quick enough for routine hooking and unhitching but secure enough to prevent casual tampering.

• Tool-free installation — quick clip-and-slide method
• Locking rod slides to selected pin position for a snug fit
• Removable with the supplied lock key for authorized users
• Low-friction aluminium body keeps operation smooth

What materials and durability features should I expect?

The lock uses aircraft-grade aluminium for the outer housing and a hardened steel rod where strength matters most. That combination keeps overall weight down while resisting corrosion and mechanical attack, so the lock remains functional over seasons of use with minimal upkeep.

• Lightweight, corrosion-resistant aircraft aluminium body
• Hardened steel locking rod for shear and cut resistance
• Weather-friendly finish to minimize rust and wear
• Engineered for long-term service and dependable security
