## Description

desertcart.com: DoorJammer Portable Door Lock Brace for Home Security and Personal Protection (DJ4LD – Lockdown (XL Edition)) : Office Products

Review: Works Great! - Works exactly as described. When placed directly below the door knob and screwed down properly — the door did not budge open when force was applied. I have used the “stick” type door stop but it stopped working in less than 2 months after the “foot pad” i.e. the part in touch with the floor (mine was vinyl tile) wore out.
Review: Security excels - No need for any photo or fancy movie to review these. These things work, they are very easy to install and very difficult, if ever, to overcome; door hardly moves while in use. I struggle to admit that anything made in China fancies me, but I am going to purchase again another set for my daughter who is an elementary teacher. Yes, that thing will definitely be handy if needs be, the "lockdown" name is quite appropriate. I do not know the material but it is strong enough to give enough minutes to be "prepared" inside a house or apartment, and also to dissuade an 'intruder' from spending interest, time and effort to overcome its 'protection'. Watch the other reviews for how to use it if you need. The instruction booklet included is written for 'supervision' which I do not have, but I can use my own logic and that was enough to learn how to operate the main item, for the extra rubber gadgets go online. I am 100% satisfied and I do not care for the price (you receive two anyway) or other brands, I will purchase a second pair right now (I received them today). Whether you call 911 or 811 these things will give you precious time on inside doors too!

## 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.

### ⭐⭐⭐⭐ Quality and heavy duty
*by G***Y on November 3, 2022*

Not a bad item. But it doesn’t work to secure a door which borders a tile floor. The unit slips off. Tried it on a carpet and cement floor and worked fine. But I needed it for a tile floor so I returned it.
