This Prime-Line Swing Bar Door Guard will increase peace of mind when answering the door by allowing the door to be cracked open slightly for viewing. When engaged, a ball on the keeper interlocks with the bar lock and prevents an intruder from pushing their way through. We have improved upon the standard door guard design and added an innovative backup thumb turn security lock that blocks the release tool from disengaging the door guard latch. In cases of emergency, hotel security or emergency crews can pop the thumb turn off of the unit by applying approximately 100 pounds of force to the door. (Note that 100 pounds of force is much greater than a simple kick in, so the emergency release feature does not compromise your security.) Additionally, after the thumb turn lock breaks away, the unit still operates as a traditional swing bar door lock and a specially designed Anti-Lockout emergency access tool is required to swing the door guard out of place. To help prevent forced entry into your home, it is always a good idea to engage the backup thumb turn lock whenever you are not actively using your door.

The adjustable panel fits most window sizes, and the clear flap lets curious cats peek outside. Simple to install and built to last, it's a thoughtful upgrade for you and your feline friend.

Works great! My cat absolutely loves it and took to it in a day. We both appreciate that she doesn’t need my help any more getting out, as raising the window was a hassle. The ability to lock it so she can only come in makes it easy to set a time when we don’t want her to go back out while still letting her come in of her own volition. Also great that we’ll be getting fewer mosquitoes in the house. I wish there was more padding included since the knobs for extending the panels make it so that the bottom is not flush with my window.
