Master Lock Trailer Coupler Latch Lock, 3-1/2 Long Shackle

The Master Lock is designed to protect against tow-away theft, whether the trailer is connected to the tow vehicle or unattached. The lock prevents the coupler latch from moving, ensuring the coupler cannot be removed from the ball or a ball cannot be placed into the coupler.

Fitting UFP and surge brake couplers, the lock features a 3-1/2" wide pin with a 9/32" diameter, a standard size on most couplers. The chrome plating enhances wear and corrosion resistance, while the precision 4-pin tumbler mechanism resists picking.

To safeguard the lock from the elements, it is equipped with a weather-tough seal and water-tight cap. The K1 key blank ensures compatibility and security.

The Master Lock's design effectively guards against tow-away theft, providing a reliable solution for trailer owners. The lock's versatility, durability, and weather-resistant features make it a valuable asset in protecting one's investment and ensuring the safe transportation of trailers.
