Taber Linear Abraser (Abrader) with Precision Knuckle Attachment

To conduct abrasion tests with the Taber Linear Abraser using a counter-face material larger than what the Universal Attachment will accommodate, the Precision Knuckle Attachment is recommended.  A threaded post and nut are incorporated, allowing you to attach a variety of materials to the spline shaft.  This unique attachment includes a ball and socket design, which enables the material to be rotated 180 degrees.
