A parallel opening hinge includes tracks pivotally connected crossing links, wherein each pair of crossing links is mounted to the tracks via a fixed pivot and a movable pivot in each track. A connector joins two movable pivots in a track such that the movable pivots move together. Improved opening of a parallel opening vent can thereby result. A pivot between links of the hinge includes a fastener holding the links together and a bushing acting on the fastener to define spacing between the links.
