If you have a door in your home that just doesn’t seem to close quite right or if you live in a neighborhood where security is an issue, then the security door stop might be just the buy for you. They come in different types and styles, some primarily concerned with stopping power, while others include an alarm system. Some of them are small enough to drop into a suitcase for use in hotel or motel rooms.
The Door Brace
A long piece of adjustable steel with a padded foot and upper fork that fits under the doorknob could be the answer for that over-zealous RA in your dorm room or to shore up the shoddy security at the only motel left in town. The rubber padding on the foot helps grip the floor without scratching and the fork holds the brace firmly in place. Excellent against forcible entry.
The Plain Old Door Stopper
While we usually think of these as holding a door open, they can also be used to help keep it closed. Think of it as passive resistance—the wedge is thin on one end and thick on the other, so when someone tries to open the door from the outside it catches on the thick wedge part. Some models have a handle to use when removing the wedge from the door.
Bells and Whistles for the Plain Old Wedge
Passive resistance isn’t always enough to prevent a problem. This is a wedge that will certainly set off alarm bells and perhaps even whistle. The thin edge of this doorstop is a switch that can be forced under the door. Once it is in place, turn the alarm on. You can set the decibel level to go from “just wake me up” to “Wake the entire neighborhood.” Some varieties imitate the sound of sirens, that should be plenty of “bells and whistles” for anyone. Uses batteries, no installation or wiring required.
Physical Stopping Muscle
Not all doors work well with either the brace or the wedge. When you encounter such a door, the Doorjammer just might do the job. It won’t sound the alarm, but it does have some serious stopping power. A little foot slips under the door, and a rubberized backing cushions a tall brace made of metal. Adjust Doorjammer with a little thumbscrew at the back of the unit for a good, tight fit that will prevent even someone with a passkey from entering your room while you are sleeping.
More Permanent Installation
If your home locks are becoming worn and you are concerned about intruders, an easy backup lock is the Defender Security U 11126 Door Reinforcement Lock. It attaches with four screws to the inside of your doorframe. In most instances, it won’t even require chiseling into the doorframe – something that could happen with a tight-fitting door. The big disadvantage is that is can only be used from inside the house – but that is also true of the wedges and the brace.
