Designed for heavy-duty industrial cleaning, this wet mop head is for use with a handle that is also sold separately. Made of 4-ply rayon, the 20 oz. looped-end mop head features a 1.5 inch tape sewn across the center. Easily laundered, the mop head's durable tail bands prevent tangles and provide remarkable floor coverage with each stroke. Mops are packaged 12 per case.
