B&W Receiver Hitch Lock TS51230 - Stainless Steel Pin for 2", 2.5" & 3" Receivers, Auto‑Lock, Anti‑Rattle

The B&W TS51230 receiver hitch lock is a stainless‑steel, auto‑locking pin that secures ball mounts and hitch accessories in 2", 2.5" and 3" receivers with a double‑ball bearing mechanism and two matched keys.

This compact lock is engineered to stop unwanted removal of hitch‑mounted gear while reducing movement and rattle during towing. Its auto‑return spring engages immediately when inserted so there’s no fumbling to align or twist the pin, and a watertight dust cap protects the cylinder against road grime and moisture. Built in the USA and supported by B&W’s Limited Lifetime Warranty, the TS51230 is meant for everyday drivers and professional haulers who want straightforward, durable security for trailers, cargo carriers, and ball mounts.

How does the TS51230 keep my hitch accessories from wobbling or rattling?

The TS51230 uses a double ball bearing locking system that seats the pin tightly inside the receiver tube, which reduces movement between the hitch and accessory. By minimizing play at the connection point the lock lowers noise and stress that can loosen components over time.

• Double ball bearings clamp the pin in place to reduce lateral movement.
• Tight fit inside the receiver helps dampen vibration and rattle.
• Stainless steel construction maintains shape under repeated use.

Is this lock easy to use day‑to‑day when connecting and removing accessories?

Yes — the lock’s auto‑return spring mechanism automatically engages as soon as the pin is pushed into the receiver, eliminating twisting or precise alignment. That makes locking faster and more convenient whether you’re hooking up a trailer in a driveway or swapping accessories at a campsite.

• Auto‑return spring locks automatically on insertion — no twisting required.
• Two matched keys included for primary and backup access.
• Watertight dust cap keeps the cylinder clean for reliable operation.

Will the TS51230 hold up to weather and salty conditions?

The TS51230 is machined from stainless steel and includes a protective dust cap over the key cylinder, so it resists corrosion from rain, road spray, and seasonal exposure. Those features help preserve smooth key operation and long‑term security in wet or winter environments.

• Stainless steel body resists rust and corrosion from the elements.
• Watertight dust cap prevents moisture and dirt from entering the lock cylinder.
• Durable finish stands up to frequent use and outdoor storage.

Which receiver sizes and accessories is this lock compatible with?

The TS51230 is designed to fit 2", 2.5" and 3" receiver tubes and will secure a range of hitch‑mounted items including ball mounts, cargo carriers, bike racks and accessory shanks that accept a standard hitch pin. Confirm the accessory’s pin hole diameter and receiver size before purchase to ensure a proper fit.

• Compatible with 2", 2.5" and 3" trailer receiver tubes.
• Secures ball mounts, cargo carriers, racks, and similar hitch accessories.
• Includes two precision keys for reliable unlocking and spares.

Who is this for?

It’s a good match for weekend campers, contractors hauling trailers, and anyone who wants a durable, American‑made receiver lock with a lifetime warranty and a simple key operation.
