Declogging rods are elastic polyurethane rods that are fixed to the screen. They work by using the machine’s vibration to move and bounce on the surface of the mesh, this avoids particles wedging and blinding the screen. The self assembly three pronged rods are fixed together with pins and they can also be configured to cover all or part of your screenbox depending on where the blinding is at its worst. They trail over the top of your mesh and bounce up and down with the vibration of the screen and knock off the material that is causing the issues.
