One-piece screening system

A screen attachment assembly comprising:

• a base extending between a first base end and a second base end, the base including a base body and a first leg, a second leg and a third leg extending from the base body, wherein the first, second, and third legs are spaced apart such that the third leg is disposed at the second base end and the second leg is positioned between the first and third legs;
• a cover pivotally connected to the first base end of the base body through a first hinge, the cover extending between a first cover end and a second cover end, the cover including a cover body and a lip extending from the cover body at the second cover end;
• and
• an integrated spline extending between a first spline end and a second spline end having a spline protrusion, the integrated spline including a spline body pivotally connected to the first leg through a second hinge, the spline body including a circular formation that projects outwardly towards the base, the circular formation being formed from a material different than a material forming the integrated spline;
• wherein:
• the cover is movable relative to the base between an open cover position and a closed cover position such that the lip engages a first third leg protrusion on a first side of the third leg when the cover is in the closed cover position, and the integrated spline is movable relative to the base separately from the cover between an open spline position and a closed spline position such that the integrated spline is positioned below the cover when the integrated spline is in the closed spline position, when in the closed spline position the spline protrusion engages with a second third leg protrusion on a second side of the third leg opposite the first side of the third leg, and
• the cover, base, and integrated spline are integrated as a single piece.
