Trailer Coupler Latch Lock for UFP and Surge Brake Couplers

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

The lock fits both UFP and surge brake couplers, and the pin length or dimensional fit is 3-1/2" wide with a 9/32" diameter pin, which is a standard size on virtually all couplers. The chrome plating on the lock improves its wear and corrosion resistance, and the precision 4 pin tumbler mechanism makes it resistant to picking.

Furthermore, the lock features a Weather Tough seal and a water-tight cap, which protect it from the elements, ensuring its durability and reliability in various weather conditions.

The K1 key blank provided with the lock adds an extra layer of security, as it is a unique key that cannot be easily duplicated, making it more challenging for unauthorized individuals to gain access to the trailer.

In summary, this Master Lock is a robust and versatile solution for protecting trailers against tow-away theft, regardless of their connection status. Its design, materials, and security features make it an effective deterrent against theft, ensuring the safety and security of your valuable assets.
