• an interior facing surface perpendicular to a plane of the sash;
• a first slot in the interior facing surface and extending longitudinally from the sill and toward the head, the first slot defining first and second opposing inner faces parallel to the plane of the sash, the first slot including:
• a chamfered portion defined at an intersection of the interior facing surface of the jamb and the first inner face of the first slot at an end of the first slot adjacent to the sill;
• and
• a transition portion between the chamfered portion and a remainder of the first slot;
• and
• a rethreading slot through the jamb and into communication with the first slot, and disposed at an end of the jamb adjacent to the sill;

• a screen material attached to the roller assembly, a leading end of the screen material coupled to the sash, the screen assembly configured to wind the screen material around the roller assembly and to permit the screen material to unwind from the roller assembly, edges of the screen material extending into the first slot of each of the two jambs;
• and
• wherein the rethreading slot facilitates automatic rethreading of the edges of the screen material into the first slot of each of the two jambs when the leading end of the screen material moves through the chamfered portion and the transition portion of the first slot during the winding of the screen material if the edges of the screen material, when not wound on the roller assembly, have been forced out of the first slot.
