While this product is smaller, less noticeable, and less cumbersome than the security bar, there is still something that has to be removed during the day and then reinstalled when you want to leave the house or go to bed. The downsides of this product are similar to the security bar. Anchored securely to the floor, NIGHTLOCK adds extra security to your Sliding Doors!

Here’s the product description from Nightlock This particular product currently has 4.5 out of 5 stars on and is very reasonably priced for what it does. Nightlock makes a lot of fantastic home security products that don’t just alert you of intruders they actually stop people from being able to enter your home at all. Whether your door is glass or not, there’s no way anyone is jiggling it open if you’ve got this installed. It really does the job of preventing people from getting in through your sliding door. You also have to remember to put it in the sliding door track when you leave the house or go to bed.Īnother great and similar option is the Nightlock Sliding Door Barricade. It’s not that it’s huge, but it’s one more thing to clutter up the entry way. You have to have a place to put that thing. My one complaint about this type of product is that the bar can be a nuisance during the day when you’re home and don’t want it blocking the door. With that in the way, there’s no way that door is sliding open. The length of this security bar is adjustable, so you just set it to the right length and lay it in the track of your sliding glass door. One of the most purchased products out there for this is the Master Lock Dual Function Security Bar.


So even if someone could jimmy the lock open like you saw in the video, they won’t be able to slide the door open because there is physically something in the way. The idea behind this option is that you actually make it so the door can’t slide open.
