Anchorage systems need to be carefully installed, if they are to offer the desired level of safety. This includes cleaning the bore holes made in concrete or masonry prior to using mortar or dowels. Use an ABS DustBrush to remove dust and particles from these holes in just a matter of seconds. This brush is available in 2 sizes to cover a broad range of bore hole sizes: Choose between our Ø 20 and Ø 24 mm models.
