The Original DoorJammer is the award-winning and police-accredited portable door security device that prevents unwanted entry, fast. Invented, designed, engineered, tested, and manufactured in-house by our team.
Installation is quick and easy - just slide DoorJammer firmly under and against the door for increased force and access protection in case of a break-in or emergency.
Immovable
Thanks to a patented system of hinges and angles, force from outside the door is redirected
downwards, wedging DoorJammer firmly into the ground.
Quick to Deploy
An easy-to-use device that can be installed by anyone and immediately works on any in-swinging door, even without a lock. Security within seconds.
Police Certified
DoorJammer is police-accredited and proven to protect from
unwanted intruders. Protect your unused back doors or feel more secure when travelling to unknown places.
