The Mirka Hiolit JCA2A0 9 x 20 in. 100 Grit T-Joint Pump Sleeve is a flexible, semi-open aluminum oxide cloth abrasive built for metal and wood workshops. Its flexible J-weight cotton backing conforms to profiles and seams, while excellent edge wear resistance and durability make it ideal for aggressive sanding where flexibility is needed. Built on a flexible j-weight cotton cloth backing with an aluminum oxide grain, this 100-grit pump sleeve is suited to blending and intermediate sanding on metal and wood, including profiles and seams. It uses a standard T-joint, cut straight through the belt without an overlap and reinforced on the back for strength and flexibility. Each box contains 10 sleeves.
