Whether you're hauling equipment across town or towing a camper on long hauls, protecting your trailer connection is essential.

In this category, explore two standout sets tailored for various hitch classes, ensuring your tow setup stays safe from theft.

Why Choose TOWWORKS for Trailer Security?

TOWWORKS has built a solid reputation in the towing accessory space for crafting locks that prioritize strength, ease of use, and compatibility. Their products feature weather-resistant coatings, precise machining for smooth operation, and innovative spans that accommodate deeper receiver tubes. Unlike generic pins, these locks emphasize double-locking mechanisms and ergonomic handles, reducing the risk of accidental release while providing quick access when needed.

As part of broader hitch accessories, TOWWORKS stands out for its focus on user-friendly features like keyed-alike systems across packs. This means one key handles your entire fleet, saving time and hassle. Shoppers in the towing products niche appreciate how these locks integrate seamlessly with everyday towing routines.

Key Features to Look For in Trailer Locks

When selecting a trailer lock, prioritize these elements to match your setup:

  • Pin Diameter: Options like 5/8-inch for heavy-duty Class III/IV hitches or 1/2-inch for lighter Class I/II applications ensure a snug fit.
  • Span Length: Extra-long spans, such as 3-1/4 inches, reach into recessed receivers on trucks and SUVs.
  • Keyed Alike: Multiple locks sharing one key simplifies security for trailers, boats, or ATVs.
  • Build Quality: Zinc or steel construction with seals against rust and dust for long-term durability.
  • Compatibility: Verify fit for 1-7/8", 2", or 2.5" receivers common in standard towing.

These features address common pain points like pin wiggle, key jamming in cold weather, or incompatibility with aftermarket hitches.

Comparing TOWWORKS Trailer Lock Models

TOWWORKS offers two versatile sets in this category, each suited to different needs. The 79632 Keyed Alike 5/8" Trailer Hitch Lock Set comes as a 2-pack with an extra-long 3-1/4" span, perfect for Class III and IV hitches on 2" and 2.5" receivers. Its double-safety design provides superior holding power for heavy trailers like utility haulers or RVs, where vibration is a concern.

In contrast, the 79692 Keyed Alike Black Trailer Hitch Lock Set includes both 5/8-inch and 1/2-inch pins, covering Class I through IV hitches universally. The sleek black finish resists corrosion, making it ideal for frequent users with mixed fleets—think boat owners or weekend warriors towing varying loads. Both models share the keyed-alike convenience, but choose the 79632 for depth-challenged receivers and the 79692 for all-around versatility.

If you're comparing brands, TOWWORKS edges out options in Master Lock trailer locks with longer spans and dual-pin packs, while offering similar reliability to Reese at a practical level. For a full selection, browse our trailer locks category.

Common Use Cases for TOWWORKS Locks

These locks shine in real-world scenarios:

  • Job Site Security: Contractors secure equipment trailers overnight with the robust 5/8" pins.
  • Recreational Towing: RV enthusiasts use the versatile 79692 set for campers and dirt bikes.
  • Fleet Management: Rental companies benefit from keyed-alike packs across multiple units.
  • Boat and ATV Hauling: The extra span handles enclosed trailers with deeper insertions.

Integrated into your exterior accessories routine, they add a layer of deterrence without complexity.
