This is a very tough, medium-soft Roloc Foam Pad Disc Holder. The holder is hook and loop to hold onto your 3" sanding discs. Five of these come in the Ultimate Sanding Kit but now you can purchase replacements or extras for your kit separately. Perhaps you'd just like to try a few of these and a mandrel stem before committing to an Ultimate 2" and 3" Sanding Kit? Either way these are very sturdy units and will give you a lot of service. See also our 3" units and matching intermittent pads.  

What is included:  One 3" Roloc Foam Pad Disc Holder
