Before entering your house or place of work, clean dirt and debris from boots and shoes using our Spectrum Boot 'N Shoe brush's angled brushes. Larger pieces of dirt and debris may be scraped off with the help of the steel scraper beneath the brush. For prolonged, continuous usage, both the block and the bristles are composed of sturdy, commercial-grade plastic. For a safe installation, the frame may be fixed to the floor using mounting hardware that is offered separately. The frame is composed of chrome steel tubing.
