Using the Condux 08081530R Duct Rodder Replacement Cage is easy. First, take out the old or damaged cage from your duct rodder. Then, simply install the new replacement cage. It's designed to fit all manufacturers' fiberglass rods, so you don't have to worry about compatibility. When using the rodder with the new cage, make sure to handle it gently to avoid any damage. For maintenance, after each use, clean the cage with a soft cloth to remove any dirt or debris. Store it in a dry place to prevent rusting. If you notice any signs of wear and tear, replace the cage promptly to ensure optimal performance.
