RIDGID have added a Ball Head and Drop Head accessory to their K9 FlexShaft Accessories range to aid blocked drain clearance. 

These will penetrate Soft & Medium blockages in the line. Drop Heads are specifically designed for dropping down stacks in back to back applications and both these accessories can be used as stand-alone or in combination with FlexShaft Chain Knockers and/or brushes.
