This Royal Blue 100% stretchable bell cover is designed to fit the bells of baritones and bass trombones. This fits most standard sized bass trombones, but players with an extra-large bell (10½” or more) might want to consider using the 12” bell cover, which will be a more comfortable fit. The bell cover reduces the risk of the harmful transmission of aerosols and droplets and is essential for all the school bands during the COVID-19 pandemic. British made by a traditional Northern textile business for Alliance Brass.
