When it comes to cutting-in, having the proper tool is of paramount importance. Create sharp, well-defined lines fast with our Angle Sash paint brushes. Angle Sash brushes have a diagonal edge, instead of being straight across. The angled end allows you to reach into corners and paint more easily along lines. Many professional painters use an angle sash brush to paint window frames and for trim, paneled doors, furniture, cabinets or anything with grooves. Or where you have to paint close to another surface, e.g. where trim butts up against walls. In other words, it is ideal for detail work.
