Schaefer Brush 35288 Square Chimney Brush 8in Steel Wire

Product Description

The SCHAEFER BRUSH 35288 is an 8-inch square chimney brush built with dense steel wire bristles for aggressive cleaning of flue tiles, masonry, and metal chimney liners. The rigid steel wire construction removes hardened creosote, soot, and debris that softer bristles leave behind. At 1 pound, the brush is easy to handle during rod-and-brush work without adding excessive weight to the cleaning assembly. It connects via a 1/4 inch NPSM male fitting, the standard thread used with most chimney brush rod systems available in the trade. Chimney sweeps, HVAC technicians, and hearth service professionals install this brush as part of routine or remedial chimney maintenance.

This brush is suited for cleaning square flue liners and fireplace chimney passages in residential and light commercial applications. The 8 inch by 8 inch square profile matches standard square flue tile dimensions commonly found in masonry chimneys. Dense steel wire is appropriate for masonry flue liners, factory-built metal chimneys, and heavily sooted flues that require mechanical abrasion to restore proper draft. It is not recommended for flexible stainless steel liner systems where softer bristle materials are preferred.

Installation Notes

This brush is installed by chimney sweeps and HVAC technicians as part of a rod-and-brush chimney cleaning system. Before use, ensure the fireplace damper is closed or the appliance is shut down and cooled to prevent ash and debris from entering the living space. Attach the brush to compatible 1/4 inch NPSM threaded extension rods before inserting into the flue. Follow NFPA 211 guidelines for chimney inspection and cleaning intervals.
