Desk Clamp - Modular Holder

Desk Clamp – Modular Holder

A modular desk clamp system that lets you attach custom accessories to your desk without drilling or damaging the surface.

The clamp mounts on the desk edge and uses a simple vertical slide-in system that lets you quickly attach and swap interchangeable holders like cup holders, headphone hooks, desk bins, cable organizers, and more. No tools, no screws required!

It is designed to be:

• Modular: one clamp, many accessories

• Quick to use: easy vertical slide-in / slide-out system

Maximum supported desk thickness: ~42 mm

If needed, you can apply a non-slip adhesive or rubber pad on the clamp to increase grip and protect the desk surface.
