If you're staying in a hotel that's kind of ... sketchy, then you might not be satisfied with simply locking your door when you're in for the night. You could wedge a doorstop of your own under it, but now there's a portable gadget that is claimed to work better – the DoorJammer.

Users start by placing the DoorJammer so that its vertical face is up against the bottom of the door, and its horizontal face is extending beneath the door. They then pull down its hinged leg, and tighten down its foot until it's firmly braced against the floor. Rubber coatings on both the faces and the foot help everything maintain a grip.

If someone should subsequently try forcing the door open from outside, the horizontal force that they apply to the door will be converted in vertical force, simply pushing the DoorJammer's foot more firmly into the floor.

In the event of an emergency such as a fire, the user can quickly remove the device by pulling up and back on its leg.

The DoorJammer is available now, for US$29.99. It can be seen in use in the video below.

No reason to spend $30 for this when $10 locks that hook into the strike have been available for decades. Google "portable door lock" to see a selection.


The principle is sound, buy why carry around this huge hunk of metal when a simple $3 rubber door wedge achieves the same thing. I have carried one in my washbag for the last 10 years. It's enough to persuade dubious people to try a different room.


What if the door opens the other side?

Sure it works on bedroom doors but what about motel room doors, or any outside doors, that have a sealed threshold. Surely it won't fit under a door like that.


So...what's the thing made out of? Aluminum? Pot metal? Blow-mold plastic? It seems to be too bulky and too much effort to implement. For far less money and far less bulk, yet about the same level of security, you would be better served with one of those deadbolt velcro strips: http://www.coolest-gadgets.com/20101019/dead-bolt-security-straps-rest-seedy-hotels/


Reduce the weight by using carbon composite. COST .... no problem just ask Chinese companies in part and pieces and assemble in US. How well the gadget will work if the surface is a rug.
