InfiniteRule Security Hitch Lock for B&W Tow & Stow 2" & 2.5" Adjustable Ball Mounts — Single 5/8" 21K Weatherproof Lock

Securely locks the ball-mount portion of B&W Tow & Stow 2" (10K) and 2.5" (18K) adjustable ball mounts — not a receiver lock.

This precision hitch lock from InfiniteRule Security is engineered specifically to fit the ball mount portion of select B&W Tow & Stow adjustable ball mounts. It uses a heavy-duty, threaded locking head with a 5/8" pin rated for 21,000 lb span strength and a weatherproof design to resist corrosion and road grime. Made in the USA by a family-owned manufacturer, the 61075 lock set protects the adjustable ball mount from theft while preserving the mount’s fit and function.

Which B&W models does this lock fit?

The 61075 hitch lock is cut to match the geometry of B&W Tow & Stow adjustable ball mounts in the 2" (10K) and 2.5" (18K) sizes. It is application-specific and will not fit the 21K model or other brands. Check your ball mount model number against the supported list before ordering.

How does the lock resist theft and weather?

InfiniteRule uses a patented threaded head-over-pin design and machined components that have undergone third-party testing for strength and tamper resistance. A rubber cap and internal O-ring help seal the locking mechanism against water, grit, and salt, reducing corrosion over time.

• Patented threaded lock head for mechanical security
• Weatherproof rubber cap and O-ring to block moisture
• Machined pin and lock body built for durability

What comes in the package and what are the key specs?

The 61075 ships as a single-pack lock set intended for the ball mount portion only. The kit includes a 5/8" pin with a 3-7/8" span that meets a 21K lb-rated pin specification, and the locking head assembled for direct replacement of the original hitch pin.

• Pin size: 5/8" x 3-7/8" span, 21K lb rated
• Sold as single unit; receiver locks sold separately (see other SKU options)

Can I use this lock in my vehicle receiver or other brands?

No — this product is not designed for the vehicle receiver or for non-B&W ball mounts. InfiniteRule produces application-specific locks; if you need a receiver lock or a universal solution, choose a SKU built for that purpose.

• Not intended for vehicle receiver use
• Does not fit non-B&W adjustable ball mounts
• Refer to InfiniteRule SKUs 61653, 61660, 61774, 61775, 61776 for receiver or other lock types
