Dust shrouds are used on angle grinders and other types of tools used to cut, grind or sand. Dust shrouds are a chamber around the abrasive that aids in capturing the dust generated by the tool at the point of generation, all with the assistance of vacuum. Most dust shrouds attempt to seal the shroud to the surface, but once you turn on the vacuum, the shroud can become suction locked to the surface and cause damage.
Patented Dust Grabber™ shrouds are designed to move air, not seal it. This patented design moves air to capture dust, eliminates 100% of suction lock, allowing the grinder to float across the surface like a puck on ice. The Dust Grabber is the only shroud that uses a replaceable polymer seal. The seal creates a vortex of moving air all around the circumference of the shroud from top to bottom, eliminating suction lock and capturing 99% of fugitive dust. The polymer seal is designed to quickly be replaced when worn out and does not require the abrasive or steel shroud to be removed when replacing the seal. The easy to replace polymer seal cuts shroud replacement cost by 75% and takes less than a minute to replace. The one piece design is not only more efficient at collecting dust , but also quicker and easier to use on the job allowing you to get as close as 1/16″ to the wall without the need for a removable edge piece.
Fits Makita GA7021 and has lifetime replacement warranty. Dust shrouds can help to prevent silicosis of the lungs, as well as prolong the life of your tools by preventing abrasive dust and debris from reaching the motors and gears.
