Hinged metal security doors designed to prevent entry from inside a home are being installed in several major cities to prevent intruders.
The doors are being fitted in the United States and Germany and are designed to make it harder for thieves to break into homes by closing off the windows and sliding the door open.
Hinged metal doors designed for use in residential homes are being replaced with more flexible metal ones, which will not be affected by the weather, said Thomas Hoehn, vice president of the Home Security Association, an industry group.
Hoehn said it’s hard to estimate how many of the doors will be installed nationwide because there are no data on how many are in use.
The association has not yet found any reports of homeowners not being able to open their doors after installing the doors, which have to be attached to a locking mechanism.
The door’s main feature is a hinge that locks into place when the door is closed.
To prevent burglaries, the hinges are not designed to be easily moved around, said Hoehm.
He said the doors are expected to be in place by the end of the year.
Hedges that can be easily removed include those designed to hold metal bars or even doors, he said.
The hinges can be attached either to a wall or ceiling to make them more difficult to access, Hoehne said.
The idea of the locks has been around for years.
But the technology is new and it’s not always obvious where to place them.
A common approach is to place the lock inside a wall, then attach a chain to a door and a string to the door itself.
But it’s unclear if this is a good idea for a homeowner’s safety, said Chris Hutton, a spokesman for the American Home Safety Association.
There are also safety issues with using hinges in a home that have not been tested.
Hoehrn said it is not uncommon for people to put their keys in a safe to open a door when someone is outside, for example, because it’s easier to move the key.
He also said there are risks associated with putting a chain in a door that is not secure.
That could mean someone could slip their hand into the chain and pull the door closed, said Peter Wessels, president of Safe-Tech, an organization that promotes better home security and uses technology to make safety better.
The locks are expected in many residential homes by the middle of next year.
