Review on Secure Your Home with the U S Patrol Sliding Door Lock: A Must-Have for Enhanced Safety by John Rivera

I installed new patio doors and it was a good low tech solution for extra security. I have a small pet door in the patio slider and when it is fully retracted someone cannot open the door with the pet door in place. Ideal. If I want it to be there when the pet door is removed, adjusting it is easy enough to address that need as well. It's made of durable metal and doesn't look cheap.
