Unlike traditional door security bars that are only temporary or that can slip on a hard floor, the Nightlock Door Barricade base plate is screwed into the floor. The vertical barricade rail slides into the base plate, creating a barrier that prevents the door from opening.
Since it is more permanent, we like that it comes in a variety of color options, including bright brass, brushed nickel, and dark bronze.
To install the Nightlock, you only need to screw in three screws. You can use the screws that come with it, or you can beef up security even more by purchasing three 3-inch #14 steel screws. You'll probably want a power screwdriver to do the job.
Because of the Nightlock's design, you need to make sure you have at least a half-inch of clearance between the bottom of the door and the floor. You might also have some trouble with the device if you have thick carpeting, because you'll need enough clearance on either side of the base plate to slide the rail in and out.
The Nightlock isn't a good travel option and may not work for renters either. It's also designed for swinging doors, so you'll have to find another solution for sliding glass doors.
Because the base plate for the Nightlock has to be screwed into the floor, it's not a good option for renters or travelers.
