The Ecoguard (Type W) Dust Shroud must be used with a vacuum, or other dust collection system, to successfully collect the dust and larger particles derived from using wider kerf diamond blades such as the Tuck Pointing or Crack Chasing blades. Includes three unique features that set this guard above its competition. First is the ability to easily adjust the cutting depth by using a simple wing nut operation. The second is the nose guide that indicates the cut line. The third is the ability to view inside the cover, while cutting, due to the clear polycarbonate material construction.
