Master Lock Stainless Steel Barbell Hitch Pin Receiver Lock 5/8 in - 3.5" Shaft, Push-to-Lock Weather-Resistant

Master Lock 1469DAT is a stainless-steel barbell-style receiver lock with a 5/8" pin and push-to-lock action that secures 2" and 2-1/2" trailer receivers against unauthorized removal.

Built for heavy-duty towing applications, this Master Lock Silver and Red Receiver Lock combines corrosion-resistant stainless steel, an extended shaft, and a weather-tight cap to protect trailers, hitches, and tow equipment. Its push-to-lock mechanism lets you lock the receiver quickly without aligning tumblers by hand, and the barbell design deters casual theft while fitting many modern trucks with factory tow packages.

How does the push-to-lock mechanism simplify hitching and unhitching?

The push-to-lock system lets you secure the hitch pin by pressing the lock body onto the pin and removing the key—no manual turn or extra steps required. It speeds up routine trailer attachment and prevents leaving the hitch unsecured when you're in a hurry.

• One-handed push-to-lock operation for fast securing.
• Key removal only after full engagement confirms a locked state.
• Swivel head design provides easier alignment in tight spaces.

Will this receiver lock fit my truck and trailer setup?

The lock uses a 5/8" (16mm) diameter shaft and an extended 3-1/2" length that accommodates both 2" and 2-1/2" receiver openings commonly found on late-model trucks. It’s specifically designed to work with heavy-duty tow packages on many Toyota, Ford, GMC/Chevy, and Dodge models, yet versatile enough for most standard receivers.

• 5/8" diameter pin matches common receiver hitch sizes.
• 3-1/2" shaft length fits standard and extended receiver tubes.
• Compatible with many pickup models with factory tow packages.

How does the 1469DAT resist weather and corrosion?

The lock is constructed from high-grade stainless steel for rust resistance and long-term durability in outdoor conditions. It includes a Weather Tough seal and a water-tight cap to keep moisture and dirt out of the lock cylinder, helping maintain smooth operation through wet seasons.

• Stainless steel body and shaft for corrosion resistance.
• Weather Tough sealing prevents moisture intrusion into the cylinder.
• Water-tight cap shields the keyway from dirt and debris.

What anti-theft advantages does the barbell-style design provide?

The barbell profile increases material thickness around the pin and lock body, making it harder to cut or pry compared with thin, exposed pins. Combined with the secure push-to-lock cylinder, it raises the effort and time required for opportunistic theft attempts, serving as a strong deterrent for trailers left unattended.

• Robust barbell construction resists cutting and bending attempts.
• Swivel head adds leverage resistance and easier access when locked.
• Bright silver and red finish improves visibility to show the hitch is locked.

Who is this for: The Master Lock 1469DAT is aimed at trailer owners, commercial users, and recreational vehicle haulers who need a durable, weather-resistant receiver lock that fits common 2" and 2-1/2" hitches. If you tow frequently, park trailers outdoors, or want a quick, reliable locking solution for heavy-duty trucks, this lock offers practical protection and convenient operation.
