Premium clamp/desk arm. Spring-tensioned articulating arm with magnetic puck (separate accessory or built-in depending on year), screw-clamp mounts to desk edges 0-50 mm thick, swing-out reach 35 cm with smooth multi-axis articulation, weighted desk-base option included for non-clampable surfaces. Clamp footprint limits where you can mount — many Japanese desks have an apron that blocks the clamp throat or a thicker top than the 50 mm range, and the desk-base alternative reclaims floor and desk space the arm was supposed to free; iPad-focused magnetic plate sizing means Android tablets and older non-magnetic iPad Mini require a third-party adapter ring plus the magnetic adapter where needed pushes total cost over 15.

The HoverBar Duo's spring-tensioned articulating arm swings the iPad anywhere within a 35 cm sphere of the desk edge and holds position without friction-hinge drift — ideal for users who constantly switch between typing and reading. Many desks have an apron skirt that blocks the clamp throat; measure yours before ordering.
Pros
- Spring-tensioned articulation holds angle without drift
- 35 cm swing reach covers typing and reading positions
- Weighted desk-base included for non-clampable surfaces
Cons
- Clamp requires 0–50 mm desk edge — desks with aprons often fail this check
- iPad-focused magnetic plate requires third-party adapter for Android and older iPad Mini
