The arm features an oversized contact wheel geometry that allows technicians to blend and feather weld seams with consistent pressure and control. It accepts 1\/4 inch or 1\/2 inch wide by 24 inch long coated abrasive belts as well as Scotch-Brite belts, giving the operator flexibility to match abrasive type to the finish requirement. A tracking and control knob is included for belt alignment during operation. Weighing 0.68 pounds, the attachment is lightweight enough for extended handheld use in fabrication and metalworking environments.\u003c\/p\u003e\n\u003cp\u003eThis attachment arm is suited for metal fabrication shops, structural welding operations, and maintenance environments where weld seams require smoothing or blending prior to finishing or inspection. It is particularly useful on pipe, vessel, and structural steel surfaces where a flat platen cannot conform to the workpiece geometry. The contact wheel contact point allows the belt to follow curved and irregular surfaces. Fabricators, pipefitters, and maintenance welders working in industrial, commercial, and shipbuilding settings are the primary users of this accessory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLarge arm design optimized for blending and feathering weld seams on curved or irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eCompatible with 1\/4 inch or 1\/2 inch wide by 24 inch coated abrasive belts\u003c\/li\u003e\n  \u003cli\u003eAlso accepts Scotch-Brite belts for surface conditioning applications\u003c\/li\u003e\n  \u003cli\u003eIncludes a tracking and control knob for belt alignment and tension adjustment\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.68 pounds for reduced operator fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compatible 3M file belt sanders that accept the Vessel 28375 arm attachment.
