MUSCATINE, IA – It’s a simple metal piece that can save lives during an active shooter setting. All you do is slip it on the door closer and it can resist up to 550 pounds of force.

Daniel Nietzel is a teacher in Muscatine and President of Fighting Chance Solutions. He says this is safety in schools is personal. “I tried to put my son in that classroom, what would I want on that door?”

He says the slam of a locker makes him worry it could be a shooter, “We live in a society now where there is potential for you to be in the middle of a lesson and someone coming into your school with a gun to kill innocent children.”

Nietzel wanted to take it into his own hands and came up with “The Sleeve”. He and four other educators in Muscatine started the company, Fighting Chance Solutions.
