Desk extender tray with 180° rotation

The CABTE ZT-03 is a desk-mounted arm rest that swings through 180 degrees to follow natural arm movement. It clamps to surfaces up to 2.1 inches thick without drilling holes. The tray measures 10.24 inches long by 5.7 inches wide and adds a padded surface for forearm support.

Clamp limits and surface constraints

The manual knob secures the unit to desks no thicker than 2.1 inches, so very thick benchtops or glass tops beyond that dimension cannot be used. The ABS frame is pre-assembled and installs in roughly a minute, but the clamp mechanism requires a flat, rigid edge to grip securely.

Padded platform and pressure relief

A 0.4 inch thick cloth-covered foam cushion covers the 5.7 inch wide platform, distributing weight across the forearm. The supplier states this reduces elbow pressure by up to 90 percent during typical typing or mousing. Users needing a larger resting area or multiple fixed positions may find the single swing arm restrictive.

Questions about this item

Which version of the CABTE ZT-03 should I choose for my desk thickness?

The clamp fits desks up to 2.1 inches thick, and the single model covers that full range without extra parts.

What does the 180° rotation actually let me do at my desk?

The arm swings through 180 degrees so you can position the tray on either side of the keyboard, supporting left- or right-handed use while keeping the elbow supported.

How does the .4 inch pad thickness affect comfort and height?

The .4 inch thick cloth cushion with high-density foam adds a soft contact surface and raises the forearm slightly above the desk edge.
