Doorjammer is a unique, new and innovative portable door security device for anyone needing privacy and security.
  The original DoorJammer sold over a quarter of a million units and our new model is lighter, smaller, and stronger than ever, making you feel totally secure in your room.
  Thanks to a patented system of hinges and angles, horizontal force exerted on the door from outside is converted to downward force, wedging the DoorJammer firmly into the ground.
  DoorJammer takes just seconds to fit to most doors and will prevent unwanted or forced entry immediately.
  Should you need to remove DoorJammer in a hurry, simply pull the handle upward. It’s designed to lift away from its locked position instantly without any fuss.
  DoorJammer is ideal for business travellers, backpackers or holidaymakers who want guaranteed security in their room. Sleep easily in a hostel, dorm, guest room or hotel - or use it in classrooms, offices and restrooms that do not have adequate locks.



If there is a large gap between the top of your door and the frame, use the provided neoprene extension foot and wedges to bolster the door, ensuring no movement can occur.


DoorJammer is proud to announce that their new portable door security device has won a Double Gold at the recent British Invention of the Year Awards in the Consumer product category.

"We only recommend those hotels that provide two independent locks, through which staff or intruders cannot enter at will. Where hotel rooms are only equipped with one lock or the locking devices are inadequate the DoorJammer is perfect for providing additional security. The DoorJammer is a compact, lightweight device and is extremely effective in keeping a door firmly secured but can be pulled off in an instant if required." Carolyn Pearson, CEO @ Ltd

How to Use

Only seconds to assemble and pack away.


Insert bottom flange into the space under the door. If your door has a high threshold, then use the extension foot as shown. Twist the bolt to the left until the engagement is secured. Pull the door to ensure it is secured.


Emergency pull off:

Our engineers have developed an easy pull off system to ensure your security.
In case of emergency you can simply pull the DoorJammer upward to easily remove it from the door.
The grip pad on the bottom flange might move during emergency pull-off. This is normal and ensures easy pull-off.
Twist bolt to the right until the foot is loose. Pull the DoorJammer upward.    

Owing to an ingenious system of hinges and angles, the horizontal force being exerted on the door from the outside is converted into a vertical force to anchor the DoorJammerfirmly into the ground.


Takes only seconds to assemble. You can fit it to most doors in seconds to 'jam' the door shut and make the occupant(s) feel totally secure and private.
