A method for manipulating a first screen assembly and a second screen assembly with respect to a screen assembly holding apparatus of a vibratory separator on which the screen assemblies are mountable;
- each screen assembly comprising screening material, a support supporting the screening material, an interconnection apparatus on the support for releasably connecting the screen assembly to an adjacent screen assembly, wherein the interconnection apparatus comprises a first lip projecting out from the support and a second lip projecting out from the support, the first lip spaced-apart from the second lip, the first lip having an upwardly projecting portion, the second lip having a downwardly projecting portion, the first lip's upwardly projecting portion located for engagement by a corresponding downwardly projecting lip portion of an adjacent screen assembly, and the second lip's downwardly projecting portion located for engagement by a corresponding upwardly projecting portion of an adjacent screen assembly, the method comprising
- positioning at least a portion of the first screen assembly with respect to screen assembly holding apparatus of a vibratory separator,
- connecting the second screen assembly to the first screen assembly by engaging the upwardly projecting lip portion of the first screen assembly with the downwardly projecting lip portion of the second screen assembly and by engaging the downwardly projecting lip portion of the first screen assembly with the upwardly projecting lip portion of the second screen assembly, and
- moving the first screen assembly and the second screen assembly together with respect to the screen assembly holding apparatus.
