Prowler Proof's Protec sliding door security screen is smart security. The mesh is a single aluminium sheet, perforated and powder coated to the high standards you’d expect from Prowler Proof. The perforations are exactly the right size – small enough to keep insects out, big enough to allow excellent airflow and transparency. Single, double or stacking slider doors - with a wide range of options and more than 300 colours to choose from.
