The BN Products Power Drywall Sander is designed for sanding drywall or plaster walls and ceilings in any position. Two interchangeable sanding heads (round orbital and triangular oscillating) provide versatility. The triangular head allows for easier sanding along edges of a wall or in corners. Built-in extension allows you to quickly change the length of the tool from 3.6ft. to 5.4ft. long. When the job is done, this tool folds in half to fit into a carrying bag.
