Dynabrade 11201 Contact Arm Assembly Dynafile Ii Series

Product Description

The DYNABRADE 11201 is a steel contact arm assembly designed for use with Dynafile II series pneumatic belt sanders. It accepts 1/2 inch wide by 18 inch long abrasive belts and features a 5/16 inch diameter crowned steel wheel with a 1/8 inch wheel width. The assembly includes a soft platen pad measuring 1/4 inch in width, allowing the tool to enter channels as small as 7/16 inch. Rated for a maximum operating pressure of 45 psig, this contact arm is intended for installation by tool and die technicians, metal fabricators, and maintenance trades working with precision abrasive applications.

This contact arm assembly is suited for deburring, blending, and finishing tasks in tight or confined workspaces where a standard contact arm cannot reach. The crowned wheel profile helps maintain consistent belt contact on curved or contoured surfaces. It is compatible with Dynafile II series sanders used in industrial, manufacturing, and fabrication environments. Compatible manufacturer model numbers listed in the input include 40352 and 40611.
