If you run a B&W Tow & Stow adjustable ball mount, you already know how convenient the flip-and-store design is. What you do not want is someone walking off with that investment — or the hitch pin vibrating loose on a rough stretch of highway. The TS51241 Pin Lock replaces the standard hitch pin with a keyed lock cylinder, securing the Tow & Stow shank in your receiver so the ball mount cannot be removed without the key. One small addition, serious peace of mind.

Purpose-Built Security for the B&W Tow & Stow System

The B&W Tow & Stow is one of the most popular adjustable ball mounts on the market, used by RV towers, truck owners, and trailer haulers who need multiple ball heights in a single hitch. Because the shank drops into a standard 2-inch receiver, it is also easy for a thief to pull it out in seconds — unless you have a pin lock installed.

The TS51241 is designed specifically for the B&W Tow & Stow family. It matches the shank diameter and pin hole geometry of the Tow & Stow ball mount, so installation is a direct swap: remove the factory hitch pin and clip, insert the TS51241 lock, and turn the key. No drilling, no adapters, no guesswork.

Keyed Lock Cylinder

Replaces the standard hitch pin with a keyed cylinder that cannot be removed without the correct key. Protects against opportunistic theft.

Direct Fit for Tow & Stow

Engineered to the pin hole specs of B&W Tow & Stow adjustable ball mounts. No adapters or modifications required.

Vibration Resistance

Lock body stays firmly seated during towing, eliminating the rattle and potential loss of a conventional clip-style hitch pin.

Weather-Resistant Construction

Lock cylinder includes a dust cover and corrosion-resistant finish suitable for outdoor, year-round use in road environments.

What the Tow & Stow Pin Lock Actually Does

The Tow & Stow ball mount is held in your truck or SUV receiver by a hitch pin that passes through the receiver tube and the hitch shank. The factory pin uses a simple hair-pin clip to stay in place — functional, but not secure. The TS51241 replaces that pin with a hardened lock body that threads through the same hole. Once locked, the shank cannot be withdrawn from the receiver. Your Tow & Stow stays put whether the truck is parked at a trailhead, a campground, or a crowded boat launch.

Protects Your Investment: B&W Tow & Stow ball mounts represent a significant investment. The TS51241 pin lock is the simplest, most direct way to prevent receiver-hitch theft — no chains, no cables, no afterthought add-ons.

Compatibility Within the B&W Tow & Stow Family

The TS51241 is designed for use with B&W Tow & Stow adjustable ball mounts that use a standard 2-inch receiver shank with a 5/8-inch pin hole — the geometry shared across the core Tow & Stow lineup. This includes the popular TSXXX series adjustable mounts sold for 1/2-ton, 3/4-ton, and 1-ton truck applications. If your Tow & Stow uses a standard 5/8-inch cross-pin (the most common configuration), the TS51241 is your lock.

Note on 2-1/2 inch receiver applications: If your truck uses a 2-1/2 inch receiver with a correspondingly larger Tow & Stow shank, verify the pin hole diameter on your specific ball mount before ordering. The TS51241 is sized for the standard 2-inch receiver / 5/8-inch pin hole configuration.

Installation — No Tools Required

• Remove the existing hitch pin and hair-pin clip from your receiver and Tow & Stow shank.
• Insert the TS51241 lock body through the receiver and shank pin hole exactly as you would a standard hitch pin.
• Insert the key, turn to the locked position, and remove the key.
• Store the key in a safe location — the lock cannot be opened without it.

Maintenance Tip: Apply a small amount of graphite lubricant or lock lubricant to the key cylinder once or twice per season, especially if the vehicle is exposed to road salt, rain, or dusty conditions. Avoid oil-based lubricants that attract grit.

What Is Included

• 1 x TS51241 Tow & Stow Pin Lock
• Keys (quantity per set — typically 2 keys included with B&W lock products)

Heads Up: The TS51241 secures the Tow & Stow shank in the receiver tube. It does not lock the adjustable head of the ball mount in the raised or stored position. If you also need to lock the flip head, look at B&W’s companion lock accessories for the Tow & Stow pivot point.

Important Information

• This lock secures the Tow & Stow shank inside the receiver tube only — it does not function as a coupler lock or wheel lock.
• Confirm your Tow & Stow ball mount uses a 5/8-inch pin hole and a 2-inch receiver shank before purchasing. Larger 2-1/2 inch receiver models may use a different pin diameter.
• Do not use this lock as the sole safety device for trailer towing. Always use safety chains and confirm all towing connections are properly secured before moving the vehicle.
• Keep backup keys in a secure, accessible location. B&W lock cylinders are keyed specifically — a locksmith may not be able to cut a replacement key without the original.
• Inspect the lock body and key cylinder for corrosion or damage at the start of each towing season.
