Very good quality product, I use it on old marching drum converted to bass drum. It clamps to the drum hoop and holds steady. Has a good range of adjustable width which shall fit to standard hoop width. Due to vibrations you have to check the clamp from time to time. It has regulated hiding spike with rubber foot, for that "extra" grip when needed on surface. Drum is not moving when played. Spurs look bulky but are very well built.
