Round Shank Brushes are used to apply lubricant to chains and other moving surfaces.  The whisking action of the bristles evenly distributes the fluid as it reaches the contact surface.  Brushes can also help prevent dirt build up. 

This brush features a horizontal aluminum holder with (2) 9/32" x 5/8" slots on the mounting bracket, and a 1/8" female NPT inlet to attach directly to a supply line.  The bristles are nylon (stainless steel is also available, part no. A2260-SR3). 

The total length of this Horizontal Round Brush with Drip Tube is 4 15/16".
