Dynabrade 11240 Contact Arm 5/8 in Power Sander

Product Description

The DYNABRADE 11240 is a replacement contact arm designed for use with compatible DYNABRADE power sanders. The contact arm serves as the interface between the sanding belt and the workpiece, guiding belt tracking and maintaining consistent surface contact during abrasive finishing operations. At 5/8 inch in diameter, this arm is sized for specific DYNABRADE sander models and is sold as an individual replacement accessory. Fabrication shops, metalworkers, and maintenance technicians typically source this part to restore worn or damaged sanding equipment to factory operating condition.

This contact arm is suited for industrial and professional finishing environments where belt sander performance depends on precise contact geometry. Typical applications include weld blending, surface preparation, and contour sanding on metal or composite workpieces. The part is packaged individually and is intended as a direct service replacement, minimizing downtime when the original contact arm shows wear, deformation, or damage from extended use.
