The present invention relates to a window and door system having an easily changeable structure, wherein: striker holders are coupled to side installation spaces of a doorframe such that the strikers are coupled and laid in the installation spaces; finishing caps are coupled to the striker holders such that the strikers are supported in the striker holders; and the strikers are laid within the installation spaces between doorframe rails with the striker holders so as not to be protrude towards an access space of the doorframe. Thus, since the strikers do not protrude within the access space of the doorframe, the window and door system can maintain an aesthetically pleasing appearance, and the strikers do not strike a part of a user's body when the user accesses the access space of the doorframe so as to prevent accidents. Furthermore, it is possible to change a locked door to an unlocked door or to change the unlocked door to the locked door by a very simple operation of replacing fixed covers or rail covers in the doorframe, and thus the structure can be changed very easily. |
