The Master Lock 379ATPY Universal Trailer Hitch Lock is designed for versatility, fitting 1-7/8 inch, 2 inch, and most 2-5/16 inch trailer couplers. It's a practical choice for securing vehicles, trailers, and RVs. Made from zinc, it promises good resistance against rust and corrosion, which is a vital feature for outdoor use.

Though the lock's zinc construction is durable, it may not be as robust as some other materials like hardened steel. The size is compact and portable, with dimensions of 5.1 x 3.5 x 4.6 inches, making it easy to store when not in use.

Users might find it straightforward to install and remove, but the key lock type means you must always have the key handy, which can be inconvenient. Its weather resistance is a plus, though extreme conditions might still pose a challenge. This product suits those needing a reliable, moderate-security lock for their trailers, vehicles, or RVs.

The lock features the Trimax Puck Lock, known for its high-security hidden-shackle design, adding an extra layer of protection against tampering.

It is coated in a bright yellow powder finish, which serves as a visual deterrent to potential thieves and enhances its weather resistance by preventing rust and corrosion. The lock is specifically designed to fit round tube gooseneck couplers, so users should ensure compatibility with their trailer before purchasing.

The Reese Towpower 7088300 is a heavy-duty trailer coupler lock designed to fit a wide range of coupler sizes, including 1-7/8", 2", and 2-5/16", making it very versatile for different trailers. Its adjustable ratchet design with 11 locking positions allows for a snug fit, improving security and reducing wobble. Made from aluminum and alloy steel, it offers good durability while being relatively lightweight at under 4 pounds. The bright yellow finish provides a strong visual theft deterrent, which can help discourage potential thieves. The lock uses theft-proof square keys, enhancing security further compared to standard key types.

Users generally find it easy to use, thanks to its adjustable mechanism and clear fit options. Since it is made partly from aluminum, it may not be as heavy-duty as some all-steel locks, and over time, exposure to harsh weather could potentially affect its finish or mechanism if not properly maintained. Still, its construction and coating suggest solid weather resistance for most climates.

This lock is a solid choice for trailer owners who want a widely compatible, secure, and user-friendly option to protect their trailer when not in use, especially if visible deterrence and ease of adjustment are important.
