A clip rail comprises an elongated body having a first end and a second end. The elongated body defines an upper recess configured to engage with one or more screen panels, the elongated body further defines a lower recess configured to engage a support member of a screening apparatus. Each of the first end and second end includes a two-platform structure, the two-platform structure configured to engage with another two-platform structure, wherein the first platform is offset from the second platform. Further, the first platform is adjacent to the second platform, and the second platform is laterally and vertically offset from the first platform, and the first platform is in a first plane and the second platform is in a second plane. The elongated body may further define first and second opposed, upper sidewalls extending upwardly along the length of the elongate body, the first and second opposed, upper sidewalls defining the upper recess, and first and second opposed, lower sidewalls extending downwardly along the length of the body, the opposed lower sidewalls defining the lower recess.
