Kestly Desk Clamp Tablet & Phone Arm — Adjustable Multi-Device Holder

A desk clamp arm for phones and tablets up to 13 inches — rigid, adjustable, and built to hold a device steady during walking pad sessions without the flex of a gooseneck design.

Gooseneck phone mounts are adequate for stationary use. Under walking, the slight vibration and rhythmic movement of a treadmill deck amplifies gooseneck flex until the screen is oscillating enough to make reading difficult. A rigid clamp arm with a lockable joint eliminates this by holding the device at a fixed angle regardless of movement below — which is why it has become a consistently recommended accessory in walking pad communities.

What it does

• Rigid arm construction holds the device at a fixed angle without gooseneck oscillation during walking
• Adjustable clamp fits desk edges and treadmill rails up to approximately 5cm thick
• Universal mount accommodates phones and tablets from 4 to 13 inches
• 360-degree rotating head allows portrait and landscape positioning

Who it's for

Walking pad users who work, study, or watch content while walking and have found standard gooseneck mounts too unstable for comfortable use. Also useful as a general desk device holder for those working in small spaces where a standing device mount would obstruct the workspace.

What's in the box

• 1 × Kestly Desk Clamp Tablet and Phone Arm
• 1 × Universal device grip (4–13 inch)
• 1 × Desk clamp with protective rubber jaw pads
• 1 × Hex key for joint tension adjustment

Tighten the joint lock fully before each session — vibration from walking can gradually loosen a partially-set arm over time.
