They offer built-in clamp and frame mounting options. Some single jam blocks use a vise-clamp or heavy-duty bracket to attach to percussion rods, while multi-block sets commonly sit in a metal frame with an adjustable thumb-screw that secures to standard drum hardware.
Individual jam blocks are typically medium-pitched. Multi-piece temple/block sets provide a tonal range — the smallest pieces produce higher pitches and the largest pieces produce lower pitches — giving you varied tones across a set.

Built-in mounting hardware commonly includes vise-style clamps and heavy-duty brackets on single jam blocks, and metal frames with adjustable thumb-screws for multi-block sets so they can be attached to standard drum hardware.
