<p>There are provided screen fittings such as an insect net or screen, including top, bottom, left, and right side frames. The bottom side frame has one end hinge-connected to the right side frame and the other end detachably connected to the left side frame. When a net is not used, the bottom side frame of the screen fittings is removed from a floor, thereby avoiding a hindrance to individuals passage and facilitating the easy removal of foreign objects such as dust from between the bottom side frame and the floor.</p> |
