Custom-fit stainless steel trailer hitch lock for compatible B&W 2" and 2.5" Tow & Stow adjustable ball mounts, using a 5/8" locking pin with a 4-1/8" span.
The InfiniteRule 61075-S trailer hitch lock is designed to help secure the adjustable platform on compatible B&W Tow & Stow ball mounts. It is a custom-fit lock for specific 2" and 2.5" B&W Tow & Stow applications, not a universal coupler latch lock or standard receiver pin.
This lock uses a 5/8" stainless steel locking pin with a 4-1/8" span to help protect the adjustable ball mount platform from theft or tampering. Its flush-style locking design, O-ring protection, and weather-resistant dust cap help support outdoor towing use.
Designed for compatible B&W Tow & Stow adjustable ball mounts
Locking pin size used for the supported B&W hitch application
Custom span for the matching B&W Tow & Stow platform setup
Corrosion-resistant construction for towing and outdoor exposure
InfiniteRule 61075-S is listed for compatible B&W 2" and 2.5" Tow & Stow 10K / 18K ball mount applications. It is not a general 7/8" span coupler lock and should not be selected as a universal trailer tongue latch lock. Verify your B&W Tow & Stow model, receiver size, adjustable platform style, pin diameter, required span, and lock clearance before ordering.
Before Starting: Confirm the ball mount is a compatible B&W Tow & Stow model and that the lock point requires a 5/8" pin with a 4-1/8" span. Inspect the pin holes, platform, and lock area for damage, rust, deformation, or misalignment. Basic Use Steps: 1. Set Ball Mount Position: Position the adjustable Tow & Stow platform at the desired height according to the hitch manufacturer’s instructions. 2. Align Pin Holes: Align the ball mount platform and adjustment channel holes. 3. Separate Lock Head: Use the key to separate the lock head from the pin by rotating counterclockwise, following InfiniteRule’s instructions. 4. Insert Locking Pin: Slide the 5/8" locking pin through the aligned holes. 5. Install Lock Head: Rotate the lock housing and pin until the internal squares align and the two halves drop together. 6. Tighten Carefully: Rotate the key clockwise until the lock contacts the O-ring, then align as directed. Do not overtighten. 7. Install Dust Cap: Seat the dust cap to help protect the keyway from water, dirt, and road grime. 8. Inspect Before Towing: Confirm the ball mount platform is fully seated, locked, and compatible with the towing setup before travel.
Package Contents: • 1 InfiniteRule 61075-S trailer hitch lock • 5/8" stainless steel locking pin with 4-1/8" span • Locking end / lock cylinder assembly • Weather-resistant dust cap • Keys as supplied by manufacturer or distributor packaging NOT Included — May Also Need: • B&W Tow & Stow ball mount • Hitch receiver • Hitch ball or replacement ball platform • Receiver hitch lock • Coupler lock or trailer tongue lock • Anti-rattle device • Safety chains, wiring, or towing hardware This listing is for the hitch lock only unless otherwise stated. Confirm your B&W Tow & Stow model, pin diameter, required span, and lock point before ordering.
To confirm compatibility before ordering, have the following ready: • B&W Tow & Stow model and weight rating • Whether the ball mount is the 2" or 2.5" Tow & Stow version • Existing lock or pin diameter • Required span across the adjustment platform • Photos of the hitch adjustment holes and lock location • Whether you need a hitch platform lock, receiver lock, or trailer coupler lock • Clearance around the lock head, keyway, and dust cap Why this matters: InfiniteRule locks are often custom-fit by application. Similar-looking locks can differ by diameter, span, receiver/hitch model, and lock point.
Match this lock by B&W Tow & Stow model, lock type, pin diameter, usable span, and lock-head clearance. Do not select it as a universal coupler lock or receiver lock.
If fitment or locking issues continue, check the B&W Tow & Stow model, lock point, pin diameter, usable span, lock-head clearance, thread condition, and key/cylinder operation before replacing additional towing parts.
Always confirm the hitch lock, ball mount, hitch ball, receiver, trailer, and towing vehicle are properly rated and compatible for the towing setup. This lock helps secure a compatible hitch component, but it does not increase towing capacity, correct an overloaded trailer, replace safety chains, or fix an improperly matched towing system. Inspect the lock before each trip and do not tow with damaged, mis-sized, loose, or improperly installed towing hardware.
