Ideal for sanding larger surface areas. The light-weight, circular design virtually eliminates flipping and allows change of direction up/down and left/right without lifting off the wall. 
Works with a 9" hook and loop sanding disc.

Features:

• Covers more surface area, especially butt joints and large seams, for faster sanding
• No flipping, scratching or gouging, like standard drywall heads, for improved control
