The ONDAIUN Desk Cup Holder is designed with an emphasis on capacity, featuring a 9.5cm inner diameter that is approximately 15% larger than industry-standard models. This extra width allows it to easily accommodate tapered 40oz tumblers and oversized bottles. The unit uses a reinforced ABS polymer chassis paired with a high-torque C-clamp mechanism for a secure attachment to the desk.
The clamping screw is built with a steel core, which helps prevent the threads from stripping when the unit is tightened. To protect your drink and the desk, integrated rubber gaskets are included to prevent container rattling and surface scratches. While the static load capacity is high, it is best used with containers up to 2.5kg to ensure the most stable performance during desk movement.
It is helpful to check the clamp tension every few weeks, as the non-slip EVA pads can compress slightly over time. This unit requires at least 4cm of desk lip depth for full structural engagement, so verifying your desk dimensions before installation is recommended.
If you prefer a metal-frame design for even more rigidity, the Sackei Deeper Metal Holder is a durable alternative. You can find more desktop space-savers by browsing our desktop shelf risers.
