We developed our Cubitron II Hookit File Sheets 737U for superior cut and long life during key stages in auto body repair. Its long lasting triangular shaped grain and multi hole pattern for superior dust extraction make the sheet ideal for paint removal, rough body filler shaping, fine feather edging or final prep before blending or priming. Our Hookit system makes for quick change outs of abrasive sheets. This abrasive is ideal for feather edging, as a final sanding step before priming, or during prep before blending.
Cubitron II and Precision-Shaped Grain
Cubitron II abrasive discs, file sheets and sheet rolls have raised the bar for high-performing abrasives. Cubitron II abrasives feature our Precision-Shaped Grain (PSG) technology, which helps provide faster cut. The result: Cubitron II cuts at least 30% faster and lasts 30% longer than conventional ceramic abrasives.

Hookit sanding abrasives conveniently and firmly attach to a hook and loop backup pad (sold separately), can be removed cleanly and easily, and can be reused again and again for the extent of the abrasive life
