The 8" Spout Brushes (36552) from Carlisle has twisted nylon bristles that help workers clean small gauges, spouts and urns without damaging the metal itself. The handle itself is made of twisted wire which makes it easier for workers to twist the brush. If a firmer grip is required, the looped end will do the job. The looped end also makes a convenient hoop for hanging the brush on a hook. Hanging the brush is better than tossing it into a drawer where the bristles can be flattened and the handle bent.
