The STATIC-H™ dust mop with keyhole backing is made with hard-wearing nylon fibres. It uses electrostatic properties to attract and hold dust particles. The tight twist yarn offers more fibre per inch, which helps hold more fine dust particles. This mop can withstand heavy use and repeated commercial laundering with virtually no fraying, tangling, unraveling and linting. It also has the ability to remove dust without the need for dust mop treatments. The sturdy polyester keyhole backing with reinforced stitching makes it a durable and versatile choice for institutional and commercial building maintenance.
