Cotton String Screw-on Replacement Head Compatible with O-Cedar, Fit All Standard American Threading Mop Handle, Cotton String Mops for Floor Cleaning (2 PCS, White)

As for “fit,” screwed into painter handle had on hand! Worked great! Appreciate getting 2 heads to have a “spare.” Use on uncovered wooden deck to clean off “tree dirt” (sap from oak %26 hickory) in between pressure washing - rinsing w/water hose just doesn't cut it. For this use, would work better if it was thicker since water spillage or wringing out isn't an issue outside. (Reason for 4 stars on quality). Happy to have found something that works for me!
