Automatic tensioning side track assembly for an operable screen

An automatic tensioning side track assembly for maintaining a retractable screen of a retractable screen enclosure assembly at a desired tensioned state, said automatic tensioning side track assembly comprising:

• a base track having a first side and a second side opposed therefrom;
• a screen receiver being adjustably positioned within said base track and configured to reciprocate between said first side and said second side;
• a first magnet being engaged with said screen receiver;
• and
• a second magnet being engaged with said base track and positioned proximate to said second side;
• wherein said first magnet and said second magnet are configured to automatically repel each other such that said first magnet is displaced away from said second magnet after said first magnet reaches a threshold position proximate to said second magnet;
• wherein a repelling magnetic force between said first magnet and said second magnet is configured to increase as said first magnet moves towards said second magnet;
• wherein said first magnet and said screen receiver are located proximately to said first side of said base track, wherein said second magnet is located distally to said first side of said base track;
• wherein said second magnet is configured to physically block said first magnet from passing beyond said second magnet as said screen receiver moves away from said first side of said base track and towards said second side of said base track.
