Model 500: The "Sentinel" Tri-Mount Chrome-Plated ABS Triple Train Horns - 307 Solenoid - 1/4" Airline
The Titan of the Road Has Arrived!
The Model 500 Sentinel is the foundation of our 500 Series train horn lineup, offering a significant step up in depth and resonance from the compact horn series. Featuring three separately tuned trumpets (16", 14", and 11"), it produces an authentic locomotive tone with a measured output of 151.8 dB. By utilizing chrome-plated high-impact ABS, we’ve engineered a horn that delivers a rich, deep sound profile without the excessive weight of all-metal units, providing a "clear the way" authority that is loud, professional, and commanding.
Advanced Air Flow & Mounting
Equipped with our high-performance Model 307 Vortex™ 4 Solenoid Valve, the 500 Sentinel ensures reliable air flow for an instantaneous, crisp blast every time you hit the switch. The ABS trumpets are mounted on a heavy-duty triangular right-angle bracket crafted from sturdy aluminum, which is designed for versatile installation on rooftops or under-body frames. A unique feature of this mount is the reversible trumpets, allowing you to face them in different directions to create a realistic, multi-directional sound effect just like a real moving train.
Professional Grade Construction and Performance
The Model 500 Sentinel is the perfect fit for the enthusiast who wants more presence than compact air horns but doesn't require the extreme, maximum-output intensity of our Top Tier 502 Kraken Horns. It offers the perfect balance of durability and performance, making it the ideal choice for trucks and SUVs looking for a legitimate train horn look and sound.
THE KLEINN 500 SERIES HIERARCHY
Model 500 "Sentinel": The Foundation of Authority
The essential Entry-Level Powerhouse for the 500 Series. Designed to be the "watchman" of the road, it provides the authentic locomotive sound Kleinn is famous for without the premium price tag. Engineered with high-impact chrome ABS trumpets, the Sentinel offers incredible durability and a mirror-like finish that stands up to the elements. Driven by our reliable chrome 307 solenoid and a high-pressure 1/4" airline, this system delivers a sharp, aggressive blast that instantly replaces your weak factory horn with a reliable and authoritative presence. It is the perfect starting point for drivers who want a professional-grade train horn that is both lightweight and incredibly loud.
Model 501 "Warlock": The Bridge of the 500 Series
The Mid-Tier. A step up in resonance and tone, this system takes performance to the next level by moving from composite materials to premium chrome steel trumpets. The result is a significant increase in resonance and tonal depth, producing a "magical" deep harmonic chord that carries much further than standard horns. Powered by our reliable chrome 307 solenoid and a high-pressure 1/4" airline, the Warlock offers the perfect balance of show-quality aesthetics and a penetrating locomotive blast. It is the ideal choice for drivers who want a richer, more melodic train sound and the rugged durability of chrome-plated steel.
Model 502 "Kraken": The Apex of the 500 Series
The Top-Tier. Engineered for those who demand nothing less than total dominance. By upgrading to the Vortex 6 VX6003 heavy-duty brass solenoid and a massive 1/2” high-flow airline, the Kraken moves a staggering volume of air instantaneously through the chrome finished steel, wide bell train horns. As the king of the family, it delivers maximum air volume and the highest output possible, producing a bone-rattling locomotive blast that is significantly louder and deeper than the entry-level models. If you want the ultimate "get out of the way" authority, the Kraken is your weapon of choice.
