Abstract
Improvements in the straightness in the vertical plane of a screen panel attached within a rectangular frame structure employing split tubes as its top and bottom edges/struts are described. Areas permitting the straightness of the screen panel to be improved include zip attachment of the screen panel to the split tubes, dependence of teeth orientation, reinforcement of the frame structure using struts, clamping of the split tubes to the frame, and modification of the screen panel, individually or in any combination thereof.
