This model is compatible with hitch racks, cargo trays, bike racks, hitch balls, and tow ropes, expanding its utility beyond simple trailer use.
Key considerations: Ensure your receiver length aligns with the 3-1/2″ active length. The updated tubular keyhole and zinc alloy lock core contribute to dependable security. Suitable for a variety of towing setups, this lock emphasizes durability and ease of use in diverse weather environments across America.

This option focuses on reliable everyday use for vehicles, trailers, and RV hitches, balancing security with straightforward operation for drivers who prioritize longevity and low-maintenance reliability.
Considerations: Ideal for users seeking corrosion resistance and a straightforward locking experience without bells and whistles. Confirm compatibility with your specific hitch tube before purchasing, particularly if you operate in coastal or snowy regions where salt exposure is a factor.

The METOWARE 3-1/2” pin model offers rugged all-metal construction with a 5/8″ diameter and a 3-1/2″ length, designed for Class III, IV hitches and larger 2″ to 2-1/2″ receivers.

Considerations: Ideal for users who need a shorter alternative to a 4″ pin while still requiring robust security. Always confirm receiver dimensions and note the compatibility limitations with double-walled tubes before ordering.
Buying Guide: Key Purchase Considerations
- Pin diameter and receiver fit: Most common are 5/8″ pins for 2″ and 2-1/2″ receivers; some larger Class V hitches use wider pins. Always measure your receiver hole diameter and confirm the maximum usable pin length for your hitch.
- Pin length and compatibility: Short pins may not engage securely on deeper receivers; longer pins provide greater engagement but must fit without striking the vehicle or accessory. Check official product specs for usable length and overall grip.
- Material and corrosion resistance: Stainless steel and carbon steel with protective coatings offer durability in rain, snow, and road salt. All-weather caps and zinc alloy cores add longevity, especially in coastal regions.
- Security features: Look for tamper-resistant designs, rotating heads, anti-drill mechanisms, and anti-rattle components. A 360-degree rotating head and a robust locking mechanism deter theft and reduce noise during transport.
- Ease of use: A simple locking/unlocking action, push-to-lock mechanisms, and clear keyways speed up routine hitching and unhitching, especially for everyday drivers and frequent travelers.
- Weather protection: All-weather key caps and dustproof seals prevent moisture and dirt ingress. This is particularly important for vehicles stored outdoors or used in winter road conditions.
- Warranty and brand support: Reputable brands with clear warranties offer peace of mind, especially if you rely on a particular lock for multiple trailers or bikes.
