Abstract: A screen deck assembly has an elongated connecting member for securing screen panels to a vibratory machine. The connecting member has a first end and a second end, a body, a transverse arm contiguous with and generally perpendicular to the body, and a radial dome top extending above the transverse arm such that a locking channel is formed between the transverse arm and the radial dome top. A screen, which has a locking profile that corresponds to the locking channel in the connecting member, is detachably secured to the connecting member by sliding or pressing the locking profile into the locking channel.
