Dust Brush 1 1\2"
The brush is made of horse hair, long 1 inch (25mm) and diameter 2.52 inch. The inside diameter of the brush is 1.25 inches, two adapter attachments / cone reducer included.
We had these DESIGNED TO FIT most standard vacuum hoses up to 1 3/4 inches. Use these to hook up to your vacuum attachments. So the outside diameter of hose and vacuum wand connected to it need to be less than 1.25 inches, about 30.5mm(1.2inch) to 42mm(1.65inch).
These vacuum hose connectors are made out of plastic and have either a tapered fit or a step fit. The smallest adapter is made out of hard plastic. Another larger ones have some give.
