Schaefer Brush 35310 Square Chimney Brush 10in Steel

Product Description

The SCHAEFER BRUSH 35310 is a 10-inch square chimney brush designed for sweeping and cleaning flue liners in residential and light commercial heating systems. Constructed with tempered steel wire bristles, it delivers the mechanical scrubbing action needed to remove soot, creosote, and debris from square-section flue tiles and metal liners. The brush connects via a 1/4-inch NPSM male fitting, making it compatible with standard chimney rod systems. It weighs 1 pound, making it easy to handle during top-down or bottom-up sweeping operations. Chimney sweeps and HVAC technicians rely on this type of brush for routine maintenance and pre-season inspections.

This brush is suited for square flue liners measuring 10 inches by 10 inches, commonly found in masonry chimneys serving gas appliances, oil furnaces, and wood-burning fireplaces or stoves. It is used in both residential service calls and commercial building maintenance where square terra cotta or stainless steel liner sections require periodic cleaning to maintain draft efficiency and reduce fire risk. The 1/4-inch NPSM male connection threads onto flexible or rigid fiberglass rod sections sold separately.

Installation Notes

Installation and use of chimney brushes should be performed by a qualified chimney sweep or HVAC technician familiar with National Fire Protection Association (NFPA) 211 guidelines for chimney maintenance. Before beginning, confirm the fireplace or appliance is completely cooled and the damper is properly positioned to contain falling debris. Connect the brush securely to compatible rod sections before inserting into the flue, and never force the brush through a section that may be blocked or structurally compromised. Wear appropriate respiratory protection and eye protection when working in or around the flue opening.
