Tension rods are used to keep hoops in place on snare toms, toms and bass drums. Hoops, in turn, keep drum heads in place. In this category you'll find a wide variety of tension rods and wing nuts, as well as rings and other such parts. Be sure to check out the rest of the drum hardware category too, where you'll find nuts & bolts, as well as specific hi-hat, cymbal, bass drum and snare drum parts.
