Diablo's premium 1/3 sheet sandpaper delivers professional-grade sanding for 1/3 sheet orbital pad sanders and hand sanding blocks. Each sheet measures 9" x 3-2/3" - the standard 1/3 sheet format that fits all major brand 1/3 sheet pad sanders.

The 400 grit (micro-fine) abrasive is built for hand-rubbed and high-gloss finish prep, final between-coat smoothing on clear top coats, and polishing prep.

• Sheet size: 9" x 3-2/3" (1/3 of a 9" x 11" standard sheet)
• 400 grit (Micro-Fine)
• Premium grain blend formulated for fast material removal and extended sheet life
• Clog-SHIELD coating reduces pitch and resin build-up from softwood and finishes
• ENDURA-BOND grit-to-backing bond resists premature grain shedding
• Compatible with 1/3 sheet orbital pad sanders and hand sanding blocks
• 10 sheets per pack

Tip: 400 grit is the threshold for hand-rubbed gloss finishes. Sand the last 2-3 top coats with 400 grit between coats, then rub out the final coat with 0000 steel wool or rubbing compound for show-quality results.
