For drummers running larger kits or adding more gear, the Gibraltar Curved Side Extension delivers serious expansion without adding clutter. This pack adds a full 40 inches of curved mounting space to either side of your existing Gibraltar drum rack. Whether you're adding cymbals, electronics, or auxiliary percussion, the Side Extension keeps everything clean, balanced, and secure. It includes a 30" support leg with an integrated cymbal arm adapter, plus a 40" curved bar, two inline T-clamps, a multi-clamp, and two memory locks. Just like the rest of the rack system, it's quick to assemble and packs down easily. Add one or both sides to suit your setup.
