MUSCATINE, IA (WQAD/CNN) - School shootings, like the one in Oregon recently inspired a few Iowa teachers to invent a device they say will secure their classrooms and help keep students safe.

No teacher wants to think they are going into a place that's a target, or what to do if there is a shooter in the building.

"When violence occurs in a school, teachers have seconds to make a potentially life-saving decision," Nitzel said, who is also of Fighting Chance Solutions.

In his training, Nitzel was taught to tie a belt around the door's closer arm - something he and his colleagues quickly realized was not a great option.

"All five rooms that the teachers were trained in, the doors were breached, the cords were ripped, and the police officer who was portraying the active shooter came in and killed all of us," Nitzel said during a presentation.

That's when he went home and designed "The Sleeve," a 12 gauge carbon steel case that goes over the door's closer arm, securing it from the inside.

Once the sleeve is on the door, it takes an incredible amount of force for the door to be opened. Making it nearly impossible for the shooter to get inside the room.

"I think it's a great product," said Chief Brett Talkington, of the Muscatine, IA police. "These shooters, what they're doing is, they're pulling on the door. If they can't get in, they're going to move on."

Nitzel stresses that it's no replacement for a door lock, and should only be used in an emergency.

"We look at it as a cheap insurance policy. If you have someone out in the hallway, and you do not want to go out into the hallway and lock your door, we want to provide you with a way to disarm that door," Nitzel said.

A simple and yet effective way that could mean the difference between life and death.

The sleeve is still awaiting a patent, but one local college is reportedly already fitting all its classrooms with the device.
