- a beam having two ends, two longitudinal sides, a top side and a bottom side;
a central bridge disposed on the top side of the beam;
a wiper strip disposed on the bottom side of the beam;
a cover having two longitudinal sides, two outer ends and a top surface;
wherein;
the cover is disposed on the top side of the beam;
the top surface of the cover has a base portion having a height and a raised portion having a height wherein the height of the raised portion is greater than the height of the base portion;
the height of the raised portion gradually decreases as the raised portion approaches the outer ends of the cover; and
wherein the raised portion has an apex that merges with the base portion before the outer ends of the cover such that multiple cross-sections of the top surface of the cover have a substantially geometrically similar cross-sectional profile along a length of a longitudinal axis that is parallel to the two longitudinal sides of the cover until the apex merges with the base portion, and wherein the base portion has a substantially constant height.
