Family owned and operated for over 35 years, we take great pride in STI’s products and exemplary service. Our entire team works just as hard to make you a satisfied customer as we do to make the world a safer place, one product at a time.
STI manufactures protective polycarbonate covers, enclosures, push buttons, heavy-duty cages and wireless alarms to help prevent theft and vandalism to important re and safety devices. Covers and cages protect: detectors, lights, manual call points, and much more. Alarms protect: re extinguishers, exit doors, etc. Many options and variations of products are available to protect the things that protect you.
The STI story begins three decades ago with a challenge made by a suburban Detroit school administrator who wanted to stop false re alarms. Our Founder, Jack Taylor, used his expertise in security systems to invent the original Stopper® pull station protector. Today, STI has hundreds of innovative products that help make homes, businesses and workplaces around the world safe, smart and secure.
