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.
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.
Replaces the standard hitch pin with a keyed cylinder that cannot be removed without the correct key. Protects against opportunistic theft.
Engineered to the pin hole specs of B&W Tow & Stow adjustable ball mounts. No adapters or modifications required.
Lock body stays firmly seated during towing, eliminating the rattle and potential loss of a conventional clip-style hitch pin.
Lock cylinder includes a dust cover and corrosion-resistant finish suitable for outdoor, year-round use in road environments.
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 Once locked, the shank cannot be withdrawn from the receiver.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.
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.
