| 1. A three-piece hinge arrangement for mounting a trough cover to a cable trough, the hinge arrangement comprising:
a) a hinge piece separate from the trough cover and the cable trough, the separate hinge piece including:
i) a clip portion having first and second arms interconnected to one another by a middle member, one of the arms defining
a window;
ii) a retaining tab provided on one of the first and second arms of the clip portion, the retaining tab protruding from the
one arm toward the other arm; and
iii) a pocket portion including first and second extension members that define a rounded channel, the first and second extension
members being interconnected to one another by the middle member;
b) a threaded fastener sized for insertion through the window of the hinge piece; and
c) a plate piece;
d) wherein during use, the clip portion of the hinge piece receives a flange of the cable trough and the pocket portion of
the hinge piece receives a pivot member of a trough cover; and
e) wherein during use, the threaded fastener is inserted through the window of the hinge piece and engages the plate piece
such that the flange of the cable trough and the hinge piece are pinched between the threaded fastener and plate piece to
prevent the hinge piece from sliding relative to the cable trough.
