Features

  • ONLY FOR INSWINGING DOORS WITH 3MM CLEARANCE - This portable, industrial strength door security device prevents unwanted entry. It takes just moments to fit in the gap under an inswinging door without needing tools and uses displacement of force to barricade the door against an attempt at forced entry.
  • TRIED & TESTED - At twice the size (a height of 192mm), Lockdown is the heavy-duty big brother of award-winning original travel safety device DoorJammer.
  • DESIGNED FOR COMMERCIAL USE - Created for emergency deployment in public buildings, schools, offices or hotels, this is the last word in portable stopping power.
  • QUICK SETUP & RELEASE - Takes only seconds to install and remove. No tools are required to implement this revolutionary home security device. In case of emergency, the quick-release easily removes the Lockdown with an upward motion.
  • HIGHLY VERSATILE - Compatible with all types of flooring, the innovative system of hinges and angles anchor the Lockdown firmly to carpeted, tiled and laminate floors when outside pressure is exerted on the door.

I purchased the DoorJammer - XL heavy weight Lockdown Edition. I travel all the time and safety has always been a serious concern of mine as I stay at various hotels and rental properties. This purchase has been a game changer. It is extremely EASY to install and uninstall the DoorJammer. Once it is PROPERLY installed, the door cannot be opened from the outside. It even comes with its own bag for easy travel. Buy immediately! ... show more

    • It’s okay
It works well especially for French doors. I bought the bigger one. My main complaint is the ridiculous price. I would have bought a couple more but I don’t think they are worth $50.

    • Excellent Security
We live in an ancient brick home with large thick doors. This device is very adjustable, & works great to secure all entrances.

    • Did not work for residential door
The device seems sturdy, however, it did not work for my basement door, I have a tile floor and it just did not work for me.

    • Never Had to Test It
Bought this for use in hotels while on a road trip. I like that it was easy to use as one person and instructions fairly easy. I ensured correct installation but thankfully never had anyone try to bust in from the other side. It's a bit heavy to carry but we'll worth the peace of mind.

    • Serves the purpose
I like it. Very easy to use and serves the purpose. Very useful especially when faced with neighbors---people who just open doors of others without knocking. It would also give a better assurance when placed under the door at night. I tried to open the door after using it and --- couldn't open it.
