3M™ Insta Lok™ 952 Firm Density Regular Hand Block, 5-3/4 in L x 3-3/8 in W, Hook and Loop Attachment

3M™ Insta Lok™ hand block is ideal for pre-preparation and final preparation of metal, wood or plastic surfaces when hand sanding is desirable. It is constructed of durable plastic that is easy to grip and has a hook and loop style attachment that firmly holds 4 x 6 in non-woven surface conditioning sheets. Constructed of firm, durable plastic, the 3M™ Insta Lok™ hand block provides the support needed to drive non-woven surface conditioning abrasives. Its rectangular 3-3/8 x 5-3/4 in design with integral handle is perfect for performing surface conditioning activities by hand. It's comfortable to hold and the block does the work, reducing operator fatigue. The 3M™ Insta Lok™ hook and loop attachment is engineered to provide a uniquely secure attachment. Tall, interlocked mushroom shaped stems provide an attachment that hold firmly, yet separates easily for sheet changes or repositioning. Moreover, Insta Lok™ hook and loop attachments stay strong through vast numbers of sheet change cycles.
