With Congress’ refusal to pass gun control legislation, it’s good to know there is one area in America where ideas can still make an impact: The good ol’ free market. Using this to his advantage, teacher Daniel Nietzel in Muscatine, Iowa has created a product with enormous potential to save the lives of children and school faculty everywhere.
His invention, “The Sleeve,” is a 12-gauge carbon steel case that fits around the door’s closer arm, preventing it from expanding and allowing the door to open, all without going into the hallway to lock the door. It is being produced by the group Fighting Chance Solutions, which claims that the durable product can withstand more than 550 foot-pounds of force.
Nietzel came up with the idea while undergoing his active shooter training for West Middle School. Teachers were being instructed to tie a belt or cord around the door’s closer arm. However, this approach was not only time-consuming after unplugging a cord, standing on a chair, and fastening a knot; it was also disturbingly ineffective. Nietzel told WQAD:
I can tell you in our training, all five rooms that the teachers were trained in; the doors were breached, the cords were ripped, and the officer who was portraying the active shooter came in and killed all of us.
The Sleeve is currently pending patent, but that hasn’t stopped Muscatine Community College from fitting every classroom and library door with the device. It is available for purchase individually at $65 each or in bulk.
