High quality, 2.3mm thick heavy duty, drum hoop for tuning down the drum head. Provides consistent shape and tension for a nice clear sound. All DrumMaker hoops are sold as a single hoop, we never force you to purchase a pair. The black finish is a black/chrome, gun-metal type look. We avoid the powder coat finish on the hoops to prevent possible chipping with extened use. NOTICE: It is very common in our industry for black drum parts to have a wide range of color variation from part to part. Example: Hoops and tube lugs may be lighter black-chrome, where rods,lugs and other parts may be a darker solid black. Please contact us before ordering if you have questions about this.
