Roofmaster offers a variety of fiberglass mops from the most efficient to budget savers. Our highest performers, the Super Spread Mop, spreads 25-30% more "hot" between trips because of it's unique twisted fiberglass fibers. It creates a large void under the band to trap more "hot" thus more colume per fill. This fiber allows the mops to last much longer than many other fiberglass mops. Super Spreads will withstand temperatures up to 1350F.
