PROBLEM TO BE SOLVED: To provide openable/closable fittings in which fixture bodies can pass each other on one rail, the cleaning is safely and easily achieved, both right and left sides can form a screen-door condition and an open condition without increasing the number of rails, and the screen doors can be used comfortably. SOLUTION: A first screen door 3 and a second screen door 4 are fitted in an upper rail portion 5b and a lower rail portion 6b so that the screen doors can pass each other.
