Hitch Lock for B&W Tow & Stow 2in and 2.5in Adjustable Ball Mount

In this review the reviewer tested the InfiniteRule Security hitch lock built specifically for the B&W Tow & Stow adjustable ball mount. The bottom line: this lock is for owners who want a tailored, heavy-duty pin for the ball mount portion only, not for the vehicle receiver. Its single biggest reason to buy is the precise fit and robust threaded lock design, which provides a confident anti-theft solution for the 2in 10K and 2.5in 18K Tow & Stow adjustable ball mounts.

Key Features

• Application specific fit: Designed to match the B&W Tow & Stow adjustable ball mount 2in 10K and 2.5in 18K, ensuring a snug, rattle-free installation.
• Robust anti-theft design: Patented threaded lock system and head-over-pin layout provide resistance to casual tampering and simple cutting tools.
• Durable construction: Corrosion-resistant materials and a weatherproof rubber cap keep the pin and lock functioning through wet and dirty conditions.
• Made in the USA: Manufactured, shipped, and serviced domestically so buyers get a unit produced under local quality control.
• Clear compatibility warning: Labeling that it does not fit the 21K model and is not intended for receiver locks prevents costly fitment mistakes.

Who It's For

This product is best for towing enthusiasts who already use a B&W Tow & Stow adjustable ball mount and want a dedicated lock for the ball mount portion. Owners of the B&W 2in 10K Tow & Stow and the 2.5in 18K Tow & Stow will benefit from the custom fit and heavy-duty pin rated at the advertised span.

It is not for buyers who need a receiver lock or who have other brands of hitch; those customers should look at full receiver lock kits or brand-specific alternatives. Also avoid this if you require a lock for the 21K model, since compatibility is explicitly excluded.

Pros & Cons

Pros

• Well machined pin and lock head deliver a sturdy, secure feel when installed.
• Weatherproof cap and O-ring reduce corrosion and keep the mechanism reliable over time.
• Perfectly fits specified B&W Tow & Stow ball mounts, minimizing play and noise while towing.
• Proudly made in the USA, supporting local manufacturing and tighter quality control.

Cons

• Limited to the ball mount portion of specific B&W models and will not work as a receiver lock, so buyers must confirm fit before purchase.
• Some users report mixed experiences on ease of use and security perception, so practice and correct installation matter.
