Sealing brushes are attached to the bottom of your router cart to seal the area for better dust collection efficiency.
For the best result it is important to always use the proper length of brushes depending on the thickness of your workpiece.
Standard kit comes with 3 sets of brushes: 20mm(0.75″), 30mm(1.1875″) and 40mm(1.5″).
If you are working on epoxy slabs we strongly recommend protecting your brushes with good quality duct tape.
Melted epoxy can permanently damage your brushes.
