Nilfisk-ALTO Clarke Encore L and S 26″ floor scrubber abrasive pad holder, two are needed for a set. Thus each one is 13 inches. HOWEVER, this part is OBSOLETE and No Longer Available and I have ONLY THIS ONE! At the moment standard postage within Australia, is capped at a maximum of $25, so maximise the saving on postage and buy something in related items below!
