The Alpha® Ecoguard Type D is a dust collection cover for drilling applications. This new innovative device helps to keep dust out of your face and off of the floor when drilling holes on walls and ceilings. The Ecoguard D captures the dust while leaving both hands free to drill. Since the dust cover is transparent, you can always see where you are drilling. Simply press the cover against the surface and drill away. Any dust or debris that results from the drilling is collected and can be easily emptied out when finished. The Ecoguard D makes jobs easier and saves the messy clean up afterwards.
