Product Description

The 3M 7000000435 is a thick standard attachment arm designed for use with 3M file belt sander systems. It provides the structural support needed to sand with either a contact wheel or a flat platen, giving technicians and tradespeople flexibility in how they approach deburring, finishing, and surface preparation tasks. Weighing just 0.28 pounds, this lightweight arm is easy to handle during setup and adjustment. It is compatible with both coated abrasive belts and Scotch-Brite belts in 5/8 inch or 3/4 inch widths by 18 inches in length.

This attachment arm is suited for metal fabrication shops, HVAC contractors, plumbers, and other trade professionals who regularly work with pipe, conduit, fittings, and sheet metal. It mounts to compatible 3M file belt sander units and allows operators to switch between contact wheel and platen sanding to match the geometry of the workpiece. The thick standard profile is intended for general-duty sanding applications where consistent belt tracking and support are required.
