This is the door jam with a built-in alarm that alerts homeowners and scares away potential intruders. Crafted from 20-gauge steel, it is designed to be used on any inward-opening or sliding door and adjusts from 28 1/2" to 45" long. When an unwelcomed guest attempts to open a door, it emits a 100 db alarm that can be heard from up to 1,100' away. It has a pivoting ball joint that ensures full contact with the floor and a padded foot that prevents marring.
