BRINKS- Portable Door Security Bar, Silver- Adjustable Security Door Jammer- Fits Standard Sliding Doors, Hinged Doors, and Windows- for Travel, Home, Dorm

We live in a 1950s house and, in order for the security bar to reach the handle of any of our interior doors, it needs to be set on the longest extension point. For the front and rear external doors, where the handles are positioned above the mid point- the jammer cannot reach.

The 4th image shows it stopping a sliding door from opening but there is no stopping from the glass from being broken.

The Brinks 675-83001 Heavy-Duty Dual Function Door Security Bar works as advertised. It is easy to adjust and install, easy to remove and replace daily or even more often, and once adjusted for any particular door and floor, is very strong and secure. Anybody trying to gain unwanted access through a door with this device properly installed will not be able to do so by opening the door the usual way. They might be able to break the hinges off the door jamb, break out the door knob or break through the substance and middle of the door, but they won't be able to open it through the latch side of the door, even if they are successful in picking the lock. The device is finely adjustable for different heights of door knobs and for different kinds of floors. I advise against using the device with the foot plate resting on carpet and certainly not with it resting on any rug or pad that could slide. That could allow tearing or slippage, either of which will allow play in the fine adjustments and will allow the bar to be dislodged under sufficient force. The adjustments are by sliding one tube inside another and using a spring-loaded button to protrude through a hole, fixing the length of the adjustment tubes. The length needs to be fixed so the angle of the tube running from under the doorknob to the floor is such that the tube is compressed when someone is attempting to open the door. I suggest two people cooperate to do the initial adjustment and installation. After that, one person can easily manage the re-installation with no adjustment required. The initial installment is done best with one person inside the door to adjust the bar length and placement and the second person outside the door to try to open it when the bar is in place and the door latch and any deadbolt are disengaged. Adjustment should allow absolutely minimal motion of the door with the latch opened. Any door motion on attempted opening requires either lengthening the adjustment tube or moving the foot plate closer to the door. Once minimum motion is achieved, the installation adjustment is complete and you are safe from anyone opening that door with the bar in place. I recommend this device highy for its intended use.

Se ve resistente, hice unas pruebas y funciona muy bien. Se ve que es muy buen producto.

très bien

I moved into my own apartment and, frankly, am paranoid. Having this really does make me feel a lot better. It's super sturdy and easy to simply pop up against the handle before bed. It's peace of mind for me and very easy to store in the corner when not in use

Item as described, good quality and grips the carpet. Overall, I am very happy with the product.
