1. A door system comprising:
a door leaf comprising a top edge and a bottom edge; and
an attachment assembly configured to rotationally couple the door leaf to an attachment member and to limit rotational travel of the door leaf to 180 degrees, the attachment assembly comprising:
a hinge pin comprising a top end and a bottom end, the hinge pin defining a vertical axis; and
a top end-cap, the top end-cap comprising a top surface and a bottom surface,
wherein the top end of the hinge pin is received within the bottom surface of the top end-cap to thereby rotationally couple the door leaf to the attachment assembly,
wherein the top surface of the top end-cap is sloped outwardly and downwardly towards the door leaf, at an oblique angle relative to the vertical axis of the hinge pin, thereby preventing an object from being anchored to the top end- cap, and
wherein the top edge of the door leaf is sloped downwards relative to the vertical axis of the hinge pin.
