3M 2-1/2 Inch x 18-15/16 Inch 400 Grit Green Trizact Belt - 5 Pack
3M's 272LA Trizact material is an embedded aluminum oxide grit in pyramid shapes on the surface of the belt. The belts give a very fine surface appearance on the glass that is a great prepatory step before polishing or fire polishing your glass. The 272LA belts are a thinner backed belt that requires a little extra pressure to grind. Be aware that the 272LA material does generate a lot of heat on your glass so take frequent breaks to prevent thermal shock on your glass while grinding.

- 3M's 272LA Trizact material is an embedded aluminum oxide in a randomized pyramidal structure to quick abrasion to surfaces
- The 272LA material is on a thinner belt backing and requires extra pressure for best results. This also generates heat on your glass, so take frequent breaks to prevent thermal shock on your glass
