Trimax 5th Wheel King Pin Lock TFW80HD — Red heavy-duty steel, weatherproof, push-button security

The TRIMAX TFW80HD 5th Wheel King Pin Lock is a heavy-duty, weatherproof locking device that secures your fifth-wheel trailer by fitting over the king pin to prevent unauthorized hitching.

If you tow or store a fifth-wheel trailer, protecting the king pin from theft is essential. The TRIMAX TFW80HD combines a full-collar, push-button locking design with ultra-tough steel construction and a durable epoxy powder coat finish to resist tampering and the elements. It installs quickly, requires minimal maintenance, and includes a limited lifetime warranty for long-term confidence.

How does the TRIMAX TFW80HD stop trailer theft?

This lock physically blocks the king pin so another vehicle cannot couple to your trailer. Its full-collar profile prevents access to the pin and reduces leverage points for thieves, while heavy-gauge steel resists cutting and prying attempts.

• Wrap-around collar design covers the majority of the king pin area
• Ultra-tough steel construction resists forced entry
• Push-button lock with secure internal cylinder limits tampering
• Bright red finish increases visibility as a theft deterrent

Is the lock durable for outdoor storage and harsh weather?

The TFW80HD is finished with a rugged epoxy powder coat that stands up to rain, road salt, and UV exposure. Sealed components and corrosion-resistant materials help keep the mechanism operational season after season.

• Weatherproof epoxy powder coat prevents rust and corrosion
• Sealed lock components reduce moisture intrusion
• Limited lifetime warranty supports long-term use
• Painted finish minimizes surface wear and fading

How easy is it to install and use daily?

Installation is straightforward: place the collar over the king pin and engage the push-button lock — no tools required for typical setup. The full-collar shape also prevents grease from transferring onto your hands, making repeated use cleaner and quicker.

• Quick push-button locking mechanism for fast protection
• No special tools needed for routine install/remove
• Full collar prevents grease transfer and keeps hands clean
• Compact design fits standard fifth-wheel king pins

What features support long-term security and maintenance?

The lock prioritizes low maintenance and high reliability through robust materials and a simple mechanical design. When occasional lubrication or inspection is needed, the straightforward construction makes upkeep easy and inexpensive.

• Heavy-duty internal components minimize service needs
• Durable finish reduces frequency of touch-ups
• Simple cylinder access for periodic lubrication
• Manufacturer limited lifetime warranty for added assurance

Who is this for? The TRIMAX TFW80HD is aimed at fifth-wheel owners who store, park, or leave trailers unattended and want a reliable, visible deterrent against unauthorized hitching. It suits RV owners, contractors with job-site trailers, fleet managers, and anyone seeking a low-maintenance, high-strength king pin lock that performs in outdoor conditions.
