PU declogging rods are elastic polyurethane rods that are fixed to the screen. They use the machine’s vibration to move and bounce on the surface of the mesh, therefore avoiding particles wedging and blinding the screen. The self-assembly three pronged rods are fixed together with pins and also configured to cover all, or part of your screenbox depending on where the blinding worse. They trail over the top of your mesh and bounce up and down with the vibration of the screen, as a result knocking off the material that is causing the issues.
