3M 7000045200 Sanding Sheet 240 Grit 2.5x100 in

Product Description

The 3M 7000045200 is an adhesive-back sanding sheet roll designed for fine surface preparation and finishing work. Built on a lightweight A-weight refill pad roll backing, the sheet uses silicon carbide abrasive at 240 grit, placing it in the very fine grade range. This combination delivers consistent scratch patterns and smooth material removal on hard surfaces including metal, composites, and finished coatings. At 2.5 inches wide and 100 inches long, the roll provides ample material for extended use in shop or field applications. Trade professionals in HVAC, plumbing, and fabrication shops use this format for deburring pipe ends, prepping brazed joints, and finish-sanding tight areas before assembly.

This sanding sheet roll is suited for light to medium surface finishing tasks in trade and industrial environments. The adhesive backing allows the sheet to be cut to length and applied directly to flat or contoured backing pads without fasteners. Typical applications include pipe and fitting preparation, surface conditioning before coating or bonding, and removal of oxidation or light corrosion from metal components. The refill-style roll format is intended to be used as a replacement supply for compatible pad roll systems.

Compatibility

Designed as a refill-style adhesive-back sanding sheet for use with standard refill pad roll systems requiring a 2.5-inch wide A-weight backing sheet.

Installation Notes

Cut the roll to the required length before applying to the backing pad. Ensure the pad surface is clean and dry before pressing the adhesive side down to achieve full contact. When using for metal pipe or fitting prep, wear appropriate eye protection and gloves. Dispose of used abrasive sections per local shop waste guidelines.
