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

Turnart Trailer Lock is an adjustable, heavy-duty hitch lock that secures 1-7/8", 2", and 2-5/16" couplers with high-visibility yellow protection.

When protecting a trailer at home, in storage, or on the road, a simple, durable coupler lock reduces risk and deters opportunistic theft. This Turnart hitch lock combines an adjustable ratchet mechanism, robust metal construction, and a bright powder-coated finish so it fits multiple coupler sizes and resists the elements while remaining easy to use.

How does the adjustable fit work for different coupler sizes?

The Turnart coupler lock uses a ratcheting adjustment with 11 locking positions so you can set a snug hold for 1-7/8", 2", or 2-5/16" trailer tongues. Adjustability removes the need for multiple locks and delivers a reliable fit across common trailer standards.

• Ratchet-style adjustment with 11 discrete positions for tight fit.
• Compatible with 1-7/8", 2", and 2-5/16" couplers—no adapters required.
• Single unit replaces several size-specific locks for convenience.

What materials and finishes protect the lock from cutting and weather?

The lock pairs a high-strength steel mechanism with an aluminum housing for a balance of toughness and weight. A powder-coated bright yellow finish improves visibility and adds long-term corrosion resistance, while an included watertight dust cap shields internal components from moisture and debris.

• High-strength steel core resists cutting and shearing attempts.
• Aluminum body reduces weight without sacrificing durability.
• Powder-coat finish and watertight dust cap protect against rust and weathering.

How easy is it to use day-to-day and what keys/accessories are supplied?

Operation is straightforward: set the ratchet to the correct position, lock it in place, and carry one of three supplied keys for access. Three keys let you keep spares for partners, friends, or emergency storage, avoiding lockouts while keeping the lock secure.

• Simple ratchet locking for quick installation and removal.
• Three keys included—primary plus two spares for shared access.
• Bright color provides a visual theft deterrent and easy spotting.

Will this lock fit my trailer and reduce tampering risk?

If your trailer tongue is one of the supported sizes, this lock provides a clear physical and visual barrier that discourages casual tampering and wheel-away theft methods. It does not replace other security layers (e.g., wheel locks or stored-location precautions) but complements them by protecting the coupler connection point.

• Works with standard 1-7/8", 2", and 2-5/16" couplers.
• Visible yellow finish helps deter opportunistic thieves.
• Use alongside hitch pins or wheel locks for layered security.

Who is this for: The Turnart Trailer Hitch Lock is intended for trailer owners who want a single, adjustable coupler lock that fits multiple common tongue sizes. It's a practical choice for boat trailers, utility trailers, campers, and anyone who prefers a visible, weather-resistant deterrent with spare keys for shared access. If you need a compact, robust lock that balances corrosion protection, cut resistance, and easy operation, this Turnart lock is built for everyday trailer security.
