This adjustable push-pull angled design uses the sides of the bristle, not the ends, to produce a superior brush finish.  Other features include our high-density polyethylene block and our aluminum extruded channel, which not only makes this brush durable but allows you to swap out the bristles with any of our other five texturing options. This option includes 1 brush of your choice, 1 Multi-Use Adapter, and 1 Chameleon Single Channel with hardware.
