Specifications include, but are not limited to: Power operated and fixed aluminum sectional doors are planned for installation along the exterior side of the existing security chain link barrier wall. The lower sectional door panels are to be fixed in-place, with a power operated and fully glazed upper sectional door mounted in vertical tracks and positioned to the exterior of the fixed sections below. When open, the operable sectional door will be in the lowered position allowing both visibility to the outdoors and fresh outdoor air to circulate within the recreation yard. When the weather is inclement or deemed too cold, the operable section will be raised to close the recreation yard to the elements while maintaining a visual connection to the outdoors through the glass panels of this operable door.
