1. Master Lock – Universal Size Fits 1-7/8″
- Brand: Master Lock
- Manufacturer: Master Lock
The Master Lock #389DAT is a mid-range universal trailer lock designed to fit 1-7/8”, 2”, and 2-5/16” couplers. Its bright red finish acts as a visual deterrent, while the advanced locking mechanism resists picking and prying. The lock is constructed with rust-resistant materials, making it suitable for outdoor use. At just 1 pound, it’s lightweight yet durable enough for most everyday applications. With a 4.7-star rating from over 17,000 reviews, this lock has earned its place as a reliable option for trailer owners.
In testing, the #389DAT performed well in resisting tampering attempts, though it’s best suited for casual theft deterrence rather than high-security scenarios. Installation is straightforward, and the universal fit ensures compatibility with most trailer couplers. However, the lock’s lightweight design may not inspire confidence for users seeking maximum strength. It’s an excellent choice for those who need a balance of affordability, ease of use, and moderate security.
Pros
- Universal fit for common coupler sizes
- Bright red finish deters theft
- Resists rust and corrosion
- Easy to install and remove
Cons
- Not as robust as premium options

2. Master Lock Black Universal Size Trailer Hitch Lock
- Brand: Master Lock
- Manufacturer: Master Lock
The Master Lock 379ATPY is a slightly more expensive model that offers similar universal compatibility to the #389DAT but with a polished black finish. Designed for RVs, horse trailers, and utility trailers, it features a zinc construction for enhanced corrosion resistance. The advanced locking mechanism resists picking and prying, and the lock comes with two keys for convenience.
While the 379ATPY shares many features with the #389DAT, its polished black finish may appeal to users looking for a more discreet option. The lock’s zinc construction provides added durability, making it more resistant to harsh weather conditions. However, at this price point, it lacks the heavy-duty build of premium options. It’s a solid choice for users prioritizing aesthetics and weather resistance.

- Zinc construction resists rust and weathering
- Includes two keys
- Polished black finish for a sleek look
Cons

- Brand: RETRUE
- Manufacturer: RETRUE

Despite its budget-friendly price, it offers a universal fit for 1-7/8”, 2”, and 2-5/16” couplers, with 11 adjustable locking positions. The lock is made from an aluminum body and A36 steel for cut and shear resistance. Its bright yellow finish serves as a visual deterrent, and the lock is rustproof and weatherproof.
For its price, the RETRUE lock delivers impressive value. It’s lightweight and compact, making it easy to store and install.

Its 120-day warranty adds peace of mind for budget-conscious buyers.
