2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.

The weather is hot in summer, and many people like to open the windows, ventilation, cool and cool. In this way, it is indeed cool, but it leaves the criminals with an opportunity.
In addition, many men do not like backpacks, mobile phones, wallets and other items will be in their pockets, and the summer dress is thin, these things are likely to inadvertently explore the head, they are targeted by the thief.
How can I avoid being caught by a thief?
1, loud screams easily lead to murder
After discovering the thief in the house, if there is no door barrier, the scream of the victim will easily cause the gangster to have a "stress response": stop the scream in the shortest time. The murder case also occurred at this time. The best solution at this time is to immediately lock the bedroom door and block the door with your body or furniture closest to you. With the protection of the door, it can be much more calm with the gangsters. In this case, almost no thief will remain in the room, and the door and the victim will compete, waiting for the police to catch up.
2, 110 busy clever "fraud" thief
A telephone should be placed in the bedroom to facilitate contact with the outside world in a variety of unexpected situations. Usually pay attention to the alarm call of the local police station, if the 110 can not be dialed, you can directly find the police station. Even if you can't remember the phone, you can "swindle" the other party, such as being close to the door, pretending to talk to the police urgently, saying loudly about your address and fierce demands for more police.
3, pay attention to observe the air conditioner outdoor unit
Special precautions should be taken for windows with air-conditioned outdoor units. The easiest way is to put two pots of flowers or a bowl of water on the window sill. Once a thief enters, it is likely to touch something and play an "alarm" role.
Residents should also observe that if the air-conditioner outdoor unit between each floor has a stepped shape, it is best to take precautions as soon as possible.
For cottage residents, installing a magnetic door alarm on the door and window is simple and economical. Up to 120 decibels of alarm sound may directly scare away the thief.
4, public places can not care
When people choose goods in the mall, they should not leave their hands. Go shopping, keep cash and valuables in your pockets and bags, and don't make money in public. When you eat, if the customer sitting behind you hurries away without ordering, be sure to check the property immediately. It is best to place the bag directly on the table, or within your front line of sight, with your hands in place.
