Automatic Sliding Screen Door Closer. A sliding screen door doesn't do much good if it's left wide open by forgetful children, or adults with their hands full. Our smooth operating "block and tackle" mechanism will close it smoothly, automatically, every time, even if someone forgets! Horizontal, hollow aluminum bar (with tension cable) attaches to the screen door top rail and frame. Adjustable tension for variable closing speeds. Installs in left or right opening doors (36" wide or wider) with just a drill, level and screwdriver.

Door-Jamming Alarm Security Bar. Help make your door "intrusion-proof" in seconds with this battery-operated door alarm. For hinged doors, a forced opening is virtually impossible when this security bar is wedged under the knob. And when the outer knob is touched or the door is pushed, it sounds a loud alarm or dog-barking sound (your choice) for five seconds; resets automatically.

Door Security Bar. Feel safe in your home with the door security bar that locks intruders out. The harder they push, the stronger this door security bar locks. Designed to secure hinged doors and sliding glass doors, the door security bar has a unique pivot-lock mechanism that "wedges-in" even tighter as more pressure is applied. Use security bars on all your sliding glass doors by placing the security bars horizontally within the door frame to lock intruders out.
