A safety front door is provided to reduce the danger of burglary and theft by receiving articles from the outside without opening a door, thereby to secure safety from people from outside. A safety front door is formed by coupling a window type security door to a front door to give and to receive articles without opening a front door. The safety front door is manufactured not to have any projected parts to look fine on the inside, and attached with a mirror to increase practicality. For safety, the safety front door is opened only from the inside and fixed at the opened state. In addition, a safety device such as a locking device of a front door is installed to heighten the safety of a safety front door. |
