Invented by firefighters, Mindr is an easily-installed fire safety device that can close a door, help slow a fire and provide precious time to protect what matters most. The product's purpose is to slow fire growth, reduce damage and create survivable space for people and pets who are unable to immediately escape. Our goal is to help protect family and loved ones and reduce property damage by closing doors automatically (but not locking) when a smoke alarm sounds. Mindr is on guard 24/7, 365.
