Trimax 5th Wheel King Pin Lock TFW80HD - Red, Heavy-Duty Weatherproof Steel with Push-Button

Trimax TFW80HD 5th Wheel King Pin Lock is a heavy-duty, weatherproof steel lock that secures your trailer by preventing hitch connection and resisting corrosion.

Designed for owners of fifth-wheel trailers who need a robust, easy-to-use barrier at the king pin, the TFW80HD blends hardened steel construction with a weatherproof epoxy powder coat and a simple push-button locking action. Its full-collar architecture keeps grease off hands while adding physical protection around the king pin, and the limited lifetime warranty backs long-term performance in outdoor conditions.

How does this lock protect my trailer when parked?

The TFW80HD physically blocks access to the king pin so a coupling head cannot engage. Its ultra-tough steel body resists cutting, prying and brute-force tampering, while the full collar design adds another obstacle around the pin area. Weatherproof coating prevents rust, keeping the locking surfaces functional over time.

• Solid hardened-steel construction deters bolt cutters and leverage attacks
• Full collar design prevents direct access to the coupling point
• Epoxy powder coat resists corrosion in outdoor storage
• Limited lifetime warranty supports long-term security

Is the Trimax lock simple to install and use?

Yes — the TFW80HD uses a push-button locking mechanism that installs quickly without tools. The lightweight yet sturdy collar slides over the king pin and locks in place with a single press, making it convenient for frequent hookups and routine storage. Removal follows the same straightforward push-button action with the key provided.

• Tool-free installation for fast on/off placement
• Push-button lock for quick engagement and release
• Compact shape for easy handling and storage
• Includes keyed cylinder for controlled access

Will the finish and materials hold up in harsh weather?

The unit is finished with a rugged epoxy powder coat that shields the steel from moisture and road salts. Combined with heavy-duty steel components, this finish minimizes surface corrosion and mechanical binding caused by salt, mud or prolonged outdoor exposure. Routine cleaning will further extend operational life.

• Epoxy powder coat provides long-lasting rust resistance
• Durable steel core maintains structural integrity under stress
• Engineered to function after exposure to rain, snow, and salt
• Limited lifetime warranty for added assurance

What practical features make this a good everyday choice?

The TFW80HD balances security, convenience and durability so it works well for regular use. The full collar keeps hands clean during handling, the push-button action saves time, and the robust materials resist common tampering methods. Its bright red finish also makes the lock clearly visible as a theft-deterrent.

• Full collar keeps grease off hands and improves grip
• Visible red finish acts as a deterrent to opportunistic thieves
• Compact footprint avoids interference with trailer components
• Easy to operate for single-person handling
