A universal blade construction adopted to fit windshield wipers having yokes with different width dimensions between the blade-straddling claws that retain the blade construction. The blade construction includes a backing strip providing a longitudinal slot-like opening formed by a pair of substantially parallel side rails which are upset at the centers inwardly of the center line of each said rail to cause a lateral bowing effect between the center and each end, whereby the blade construction will fit snugly in between claws of different width.
