A universal trunnion and bracket system for shade rollers in which the bracket is aligned with the centerline of the roller. The trunnion is rotatably mounted in an end of the roller. A lug, offset from the centerline of both the trunion and the roller, protrudes from the trunnion. The bracket has several (usually three) slots with tapered sides to match the tapered sides of the lug. The roller is mounted to the bracket by lowering the end of the roller until the lug engages a slot in the bracket, the non-circular shape of the lug and the slot preventing rotation of the trunnion with respect to the bracket.
