When Seconds Count…

When seconds count and help is minutes away, patent pending JustinKase is there for the added protection of students and staff. Unlike other products, JustinKase does not allow a door to open even when door locks are completely compromised by gunfire. This allows extra time for emergency personnel to arrive on scene.

The JustinKase Universal In-Swings slide under the door and extend out to fit around the base of the door frame keeping the door secure and intruders out.

The JustinKase Out-Swing Door Arm slides into the holder, attaches to the door and hooks over the door frame to secure the door from being swung open.

Our Story

When a shop teacher challenged his students to build a device which could increase school safety, Justin Rivard rose to the occasion.  Only 15 at the time, he researched current products and then sought to learn their strengths and weaknesses. After months of refinements, JustinKase was engineered, built, refined, and is now helping protect thousands of students in Wisconsin & Minnesota.

While school shootings like Sandy Hook, Columbine, and others gain the headlines, school districts around the country experience dozens of lockdowns due to various security concerns. Is your school truly ready to protect the students & staff?

The nation took notice. Justin has been featured on so many different media outlets it is hard to keep track. Why? While adults have argued over various political topics, Justin took control into his own hands to develop something which doesn’t fall political categories. We’ve tried to keep up with our media page but that isn’t nearly as important as the mission we seek to dominate: safety.




What Type Of Door Does JustinKase Work On?

  • In-Swing Universal fits doors between 28-42 inches in width

  • Works best on flat surfaces under the doors.  Some doors do have small metallic “lips” under the door which may or may not impact product performance.

  • Out-Swing Door Arms are designed to work on virtually any out swinging door.

Will The JustinKase Work On Residential Doors?

The device is not designed for residential doors but it might work in some cases.  We will look to offer new products in the future which might be a better fit for the homes but the current focus is on schools and industrial doors.
