Four-pack keyed-alike stainless steel lock set for compatible B&W 2" and 2.5" Tow & Stow 10K and 18K adjustable ball mounts, including three hitch locks and one receiver lock.
The InfiniteRule 61775-S is a four-pack keyed-alike lock set designed for compatible B&W 2" and 2.5" Tow & Stow 10K and 18K adjustable ball mounts.

InfiniteRule 61775-S is for compatible B&W 2" and 2.5" Tow & Stow 10K / 18K adjustable ball mounts. It includes locks for the adjustable hitch section plus one receiver lock for compatible 2" or 2.5" receiver applications. It does not fit the B&W 21K Tow & Stow model. Verify the exact B&W Tow & Stow model, hitch rating, receiver size, pin diameter, required span at each lock point, and lock-head clearance before ordering.
Before Starting: Confirm the hitch is a compatible B&W 2" Tow & Stow 10K or 2.5" Tow & Stow 18K adjustable ball mount and that the receiver lock span matches the vehicle receiver setup. Do not use this kit on the B&W 21K model unless separately verified by InfiniteRule. Basic Use Steps: 1. Confirm Hitch Model: Verify the Tow & Stow model, rating, receiver size, and lock point dimensions. 2. Install Hitch Shank: Slide the compatible hitch shank fully into the receiver and align the receiver pin holes. 3. Install Receiver Lock: Use the included 5/8" x 3-1/8" span receiver lock at the receiver connection if the span and clearance match. 4. Set Ball Mount Position: Position the adjustable ball mount/platform according to B&W instructions. 5. Install Hitch Locks: Use the three 5/8" x 4-1/8" span hitch locks at the compatible Tow & Stow adjustment lock points. 6. Confirm Engagement: Pull gently on each lock to confirm it is fully seated and secured. 7. Install Dust Covers: Seat the dust covers to help protect the lock cylinders from water, dirt, and road grime. 8. Inspect Before Towing: Confirm the hitch, receiver, ball platform, lock locations, and towing setup are secure and properly rated before travel.
Package Contents: • 3 InfiniteRule 5/8" hitch locks with 4-1/8" span • 1 InfiniteRule 5/8" receiver lock with 3-1/8" span • Keyed lock assemblies • Weather-resistant dust covers • Keys as supplied by manufacturer or distributor packaging NOT Included — May Also Need: • B&W Tow & Stow hitch • Trailer hitch receiver • Trailer coupler lock • Trailer latch lock • Hitch ball or replacement ball platform • Anti-rattle device • Safety chains, wiring, or towing hardware This listing is for the four-pack hitch and receiver lock set only unless otherwise stated. Confirm the exact B&W hitch model, receiver size, pin diameter, and required spans before ordering.
To confirm compatibility before ordering, have the following ready: • B&W Tow & Stow model number and weight rating • Whether the hitch is a 2" 10K or 2.5" 18K Tow & Stow • Whether the hitch is a 21K model, which this set does not fit • Receiver size and required receiver lock span • Pin diameter at each lock point • Required usable span at each adjustable hitch lock point • Photos of the hitch adjustment area and receiver connection if fitment is uncertain Why this matters: This is a mixed lock set. Three locks are for the adjustable hitch portion and one lock is for the receiver connection. Using the wrong lock in the wrong location can cause fitment or safety issues.
Match this lock set by B&W Tow & Stow model, hitch rating, receiver size, lock location, pin diameter, usable span, and lock-head clearance. Do not select it as a universal 2" receiver lock combo.
If fitment or locking issues continue, check the B&W Tow & Stow model, hitch rating, receiver size, lock location, pin diameter, usable span, lock-head clearance, and whether a different InfiniteRule kit is required.
Always confirm the hitch locks, receiver lock, adjustable ball mount, hitch ball, receiver, trailer, and towing vehicle are properly rated and compatible for the towing setup. These locks help secure compatible hitch and receiver points, but they do not increase towing capacity, correct an overloaded trailer, replace safety chains, or fix an improperly matched towing system. Inspect all locks before each trip and do not tow with damaged, mis-sized, loose, or improperly installed towing hardware.
