Abstract
This disclosure discloses a shaker screen. The shaker screen comprises a frame and at least one screen layer supported by the frame for sieving materials. The frame comprises a rectangular outer support structure, at least one lateral inner support member, and at least one longitudinal inner support member. The lateral inner support member comprises an aperture, and the longitudinal inner support member comprises a groove on a side of the longitudinal inner support member. The lateral inner support member is engaged with the longitudinal inner support member by engaging the aperture on the lateral inner support member and the groove on the longitudinal inner support member.
