A system and method allow for the installation and removal of curved screen elements from a shaker table. Pneumatic cylinders are used to move hold down bars either up to allow for screen elements to be installed or removed from the screen bed section assembly, or down to clamp screen elements into the screen bed section assembly of a shaker so that the screen elements will not move during shaker operations. Each curved screen element may have a different radius. Self-adjusting hold down bars compensate for adjacent screen elements having edges that are parallel but at different elevations. The self-adjusting hold down bars also compensate for adjacent screen elements having edges that are not parallel.
