Master Lock Receiver Hitch Pin Lock 5/8 in Silver/Red — Stainless Steel Barbell, Weather-Resistant

Master Lock 1469DAT is a weather-resistant stainless steel Barbell™ receiver lock that secures 5/8" trailer hitches with a push-to-lock mechanism for quick, reliable protection.

Protect trailers, boats, campers and heavy-duty towing gear with a purpose-built receiver lock engineered for tough conditions and heavy-use trucks. The Master Lock 1469DAT combines a 5/8" stainless steel locking pin with an extended shaft and a watertight cap to resist corrosion and keep dirt and moisture out of the locking mechanism. It was designed to work with modern trucks equipped with heavy-duty tow packages and fits both 2" and 2-1/2" hitches when an extended length is required.

How does the push-to-lock system make hitching faster?

The push-to-lock design lets you secure the hitch in one smooth motion: insert the pin and press the lock body down until it clicks, then remove the key. No complex dial settings or multiple steps are required, saving time while maintaining a secure engagement.

• Insert 5/8" stainless steel pin through receiver and ball mount
• Push lock body until it seats and engages automatically
• Remove key; lock remains secured without further action
• Swivel head simplifies alignment when threading through attachments

Will this lock hold up to weather and road conditions?

The 1469DAT uses corrosion-resistant stainless steel and a Weather Tough seal to protect internal components from moisture and grime. A water-tight cap over the keyway further shields the cylinder from salt spray and road debris, extending functional life in coastal or winter conditions.

• Stainless steel construction resists rust and pitting
• Water-tight cap protects the keyway from contaminants
• Weather Tough seal reduces moisture intrusion into the cylinder
• Swivel head design keeps components aligned and reduces wear

What vehicles and hitch types is this receiver lock compatible with?

The lock is sized for a 5/8" (16 mm) receiver pin and features an extended 3-1/2" shaft, making it compatible with many late-model trucks and heavy-duty tow packages. It fits both standard 2" and larger 2-1/2" hitch receivers when used in extended positions, and is commonly used on full-size trucks and heavy trailers.

• Fits 5/8" receiver pin applications (16 mm)
• Extended 3-1/2" shaft for 2" and 2-1/2" hitches
• Suitable for trucks with heavy-duty tow packages (e.g., full-size pickups)
• Works with trailers, ball mounts, and tow accessories needing a robust lock

How does construction and design improve theft deterrence?

Robust stainless steel construction and a barbell-style shaft increase resistance to cutting and leverage attempts compared with thin, plated pins. The solid design plus the push-to-lock cylinder reduces exposed moving parts and makes unauthorized removal more difficult.

• Thick 5/8" stainless steel pin for added strength
• Barbell-style shaft reduces leverage points for pry tools
• Swivel head allows clean insertion and reduces binding
• Minimal exposed mechanisms limit attack surfaces for thieves

Who is this for: The Master Lock 1469DAT is aimed at truck owners, fleet operators and trailer users who need a dependable, low-maintenance receiver lock for frequent towing or long-term storage. If you tow boats, campers, horse trailers or heavy loads and want a weather-resistant, easy-to-operate lock that fits modern heavy-duty tow packages, this model offers a practical balance of durability and convenience without complicated installation.
