I own a Rotex RO 150 FEQ sander (it's an older model). I need a replacement sanding pad as the original pad has come apart. Is this a complete unit that attaches directly to the machine spindle? Is the product I am found for "Festool 202463 Multi Jestream2 Hard Pad for Rotex 150 FEQ the correct replacement? I appreciate your attention to my inquiry.

As long as your Rotex RO 150 FEQ was purchased after 2007, it will use Festool's "Fastfix" style pad which does not have a bolt used for attachment. It simply twists to lock onto the sander spindle. Any of the pads below will work. The sander originally ships with a soft pad (202461). Note that earlier this year, Festool updated the 150mm (6") pads to have more holes. But, the older sandpaper will work with it even it it has fewer holes.https://www.festoolproducts.com/accessories/sanders/pads-1/rotex-ro-150-pads.html
