Klingspor KL 381 J Abrasive Cloth Roll 150 mm x 30 m P36 Aluminum Oxide

When sanding large surfaces by hand or with a machine, standard sheets wear out quickly and create uneven results. The Klingspor KL 381 J abrasive cloth roll solves this by providing a continuous 30-metre length of high-performance P36 aluminum oxide on a flexible J-weight cotton backing. Cut it to any size you need, from small strips for detail work to long sections for floor sanding, and keep working without constant sheet changes.

Tips

For best results, tear or cut the cloth against a straight edge to avoid fraying. Use a sanding block for flat surfaces and wrap the cloth around a contoured pad for curved work. Store the roll in a dry place to preserve the cloth backing and prevent premature loading. Always wear appropriate dust protection when sanding painted surfaces.
