Just like magic, the HoudiniTM simplifies your choice of keyboard arms, because it works just about anywhere and does just about anything. Short return? Corner work surface? No problem! The Houdini pulls out far enough to work in a corner but still retracts fully on a short, 17.75” track. Plus, it adjusts quickly and easily to follow various postures for low-risk keyboard positions. Positive tilt lockout available.
