From Police Officer to Product Inventor: Bill Barna's Mission to Protect Classrooms Bolo Stick door barricade. For anyone evaluating classroom security products or trying to understand what sets this device apart, the interview is worth watching in full. A 33-Year Career in Law Enforcement Barna spent more than three decades as a police officer in Ohio. Over that career, he witnessed the evolution of active shooter response firsthand — from the pre-Columbine era of perimeter-and-wait tactics to the modern Single Officer Response Technique (SORT) that sends the first arriving officer directly toward the threat. That professional background gave him an intimate understanding of two realities: how quickly an attacker can inflict casualties, and how long it actually takes for law enforcement to arrive and neutralize a threat. The Invention Story: 2012-2013 The idea for the Bolo Stick emerged in 2012-2013, when Barna's own children were attending school. The surge of active shooter incidents in educational settings had reached a point where a career police officer couldn't ignore the vulnerability of standard classroom doors. Most classroom doors at the time relied on basic commercial locks — hardware that a determined intruder could defeat in seconds, particularly doors with glass panes that could be broken to reach the lock mechanism. Training programs like ALICE (Alert, Lockdown, Inform, Counter, Evacuate) were spreading through school districts, but they focused on behavioral response without physically hardening the door itself. Barna approached his local school superintendent and principal with the concept. They were receptive, and he began prototyping. By his own admission, he is "not a mechanical guy, just an idea guy" — but the idea was sound: a floor-mounted barricade that uses physics and high-strength steel to make forced entry extraordinarily difficult. How the Device Works The Bolo Stick consists of three components: a mount that attaches to the inside of the door with two stainless steel screws, a safety anchor that extends an inch and a half into the floor, and a 5.5-inch steel pin that locks the door in place. All components are manufactured from 1045 cold-rolled steel. Independent testing has confirmed the device can withstand more than 4,200 pounds of force — a figure that puts it in a different category from standard commercial door hardware. In one widely cited anecdote, a SWAT team spent 20 minutes attempting to breach a door equipped with a Bolo Stick. They destroyed part of the door itself, but the device held. The Bolo Stick is currently deployed across 39 states and 6 countries. The company is an Associate Member of the National Association of School Resource Officers (NASRO). Affordability as a Core Principle One of the most striking details from Barna's interview is the pricing history. The Bolo Stick launched at an MSRP of $99 per unit — within the median range for door barricade devices. But after consistent feedback from school administrators at trade shows, Barna restructured the manufacturing process and cut the price to $69 per unit. The Bolo Stick's mission is quite simple. It's not about making millions of dollars. It's about making millions of products and safeguarding lives. That pricing decision reflects a philosophy that prioritizes deployment volume over profit margins. For schools operating on razor-thin security budgets, especially in an era where every dollar is scrutinized, an affordable barricade that protects an entire classroom is an easy decision. The Tagline: Strong, Simple, Safe Barna describes the company's tagline as a direct reflection of the product: "Strong" refers to the 1045 cold-rolled steel construction. "Simple" means a one-step operation — no special training, no fine motor skills required under stress. "Safe" is the outcome: preventing unwanted entry to protect the people inside. For schools, churches, businesses, and homes looking to add a physical security layer that actually works under pressure, the Bolo Stick represents an approach grounded in law enforcement experience rather than marketing theory.
