Stuttertone® Is a Registered Trademark of Grover Products Co.

For decades, the name Stuttertone®has been associated with one unmistakable sound: the rapid, attention commanding warning tone used on fire apparatus, emergency vehicles, heavy equipment, and specialty vehicles across North America.

What many people do not realize is that **Stuttertone® is not a generic industry term. It is a registered trademark owned exclusively by** Grover Products Co..

The Origin of Stuttertone®

Grover Products Co., founded in Chicago in 1936, invented and popularized the modern emergency air horn, among other horns. Over the years, Grover became known for manufacturing premium brass air horns used on fire engines, emergency vehicles, heavy trucks, marine vessels, military vehicles, and industrial equipment.

Among Grover’s most recognizable innovations is the Stuttertone® emergency air horn, designed to create a distinctive interrupted blast pattern that immediately captures attention in traffic and emergency situations.

Stuttertone® Is Protected Intellectual Property

The name Stuttertone®is legally protected intellectual property belonging to Grover Products Co. The trademark identifies the source and origin of the product, distinguishing authentic Grover manufactured systems from knockoff products.
