A shaker apparatus including a basket having an upstream side, a downstream side, and two side walls, at least one wedge guide and one support rail disposed on each side wall, and at least one screen assembly. The support rails and the wedge guides may be configured to engage the screen assembly. The screen assembly may have one or more layers of screen mesh mounted on a screen frame. The screen frame may include a first and a second side rail, each having an upstream end, a downstream end, a top surface, and a bottom surface. A slope of the top surfaces intermediate the upstream end and the downstream end may be different than a slope of the bottom surfaces intermediate the upstream end and the downstream end.
