Fitting a 5/16" Sanding Pad to RO 150?

[extiger]

I've got an older RO 150 E+ and want to fit a 4" brush to it. The brush has its own backing plate with a 5/16" threaded screw. Will this mate to my Festool or is an adapter available?

For cleaning car carpets.

There is no adapter available from Festool. You'll have to figure something out yourself to do this. Be aware of the risks of fitting something that wasn't intended for it.
