One Florida elementary principal wasn't satisfied with the security of his classrooms. His solution? A custom designed locking mechanism dubbed the Z-lock that is designed to prevent access to classrooms.
Jason Pursley, the principal of the Skyline Elementary School, invented his own version of a lock that he feels will be a much more secure option for keeping unwanted intruders out of classrooms. Buffalo Prairie Middle School is the latest school to implement the Z-lock.

The Z-lock allows a teacher to quickly lock the door securely to stop an intruder from entering, and anyone else from leaving. Dallas County R-1 School District Superintendent Tim Ryan said, "In some cases, we may want to evacuate students from the building. But if that’s not possible and there is an intruder in the halls, teachers will be able to quickly lock their classroom doors."
"Without the Z-Lock, teachers would have to step outside to lock the door."
Part of the heavy duty Z-lock hangs on the wall next to the door and the main part of the lock is attached to the door itself. "In case of an intruder alert, the teacher can grab the Z and put it in the lock in 20 seconds or less," said Buffalo Prairie principal Buck Shockley.
The Z-lock is being installed in every middle school classroom in the district. Ryan has yet to order the Z-lock for all R-1 buildings but he did say he is planning to once he sees how well it works and how long it takes to install.
Pursley said he has been looking into security devices for classroom doors at Skyline Elementary but didn't like anything he found prior to designing the Z-lock. "We would have to drill a lot of holes in the doors, and the cost was going to be $125 or $150 per door," Pursley said.
"One day I just started working on a design, and in August I started putting some locks together."
To help produce his newly invented lock, Pursley started a company called DK Safety Solutions and makes the locks himself. The Z-lock costs a mere $35 dollars and the demand has grown. It has already been installed in nine schools, Skyline, Buffalo Prairie, Fair Grove, Halfway, Bolivar Co-op, Lakeland, Pleasant Hope, Fair Play, and Dadeville.
