Condor Ringer Head Item No. C289-1-000XMB Stored in my home warehouse. There is rust on the inside (see image 5), and other dirt. Turning the black knob seems to widen the frame (see image 4). I have included as many images as possible, so please take a look. For the listing, I have washed it once with water using a sponge. Please understand that this is a used item. Please refrain from purchasing if you are sensitive to imperfections or are looking for a perfect item. No claims and no returns accepted. #MopWringer
