Testimonials
Formerly knows as DoorJam
Safety. One of the guarantees I understood, or assumed, would come with being a teacher. It was a safe job. I could feel safe at a school. We do not live in a country where I feel that way anymore. However, SLON is bringing safety back. With the SLON I’m confident an intruder won’t be able to enter by opening the door. With that security, I can ease my mind to focus on next steps. The sleek design makes it easy to use in a moment’s notice. The simple design also makes it unnoticeable, so it fits any decor and isn’t obstructing someone’s pathway. I’m grateful that our campus has them.

I am a high school teacher with two glass doors for my classroom. Before receiving the SLON safety device, I was always a nervous wreck when practicing shooting drills. One day, my door did not lock during a live drill; I was devastated at the thought of what could have happened. Now that I have a safety device for both of my doors, I feel more protected and a great sense of relief at the added layer of security for my students. Now I know we are truly protected from an intruder trying to gain access to my classroom.

SLON safety device is a literal life saver! Ever since the device was installed on my classroom door I instantly felt like my students would be safer. If there were ever a true emergency, I now feel a sense of safety from the outside world !
—Emily DeSantis (High School Teacher)
I am currently a high school teacher. I have been through several lockdowns with and without the SLON safety system. I cannot stress enough the difference the SLON safety device has made when it comes to our safety and peace of mind. The lock is sturdy, reliable and easy to use. It is the perfect lock for emergencies. In our most recent lockdown, my students and I felt much safer throughout the incident. We trust the SLON lock. I highly recommend it!

“Most recently, what we did this summer, we invested some money in a device called the ‘door jam,’” said Troncoso. “A lot of school buildings, they have locks outside the door. So, when there’s a lockdown, [teachers or substitutes] have to literally open the door, go outside, and lock the door.
