Does the table hub fall through the freshly drilled or existing hole? If the table hubs don't fit because the existing cable grommet is too large, the IB-HUBA001 comes into play. With this adapter ring, there's no need to drill another hole in the table, as it allows for the perfect installation of the table hub. This stylish adapter is an ideal addition for any desk that previously lacked a table hub. Thanks to its subtle black color and polycarbonate housing, every ICY BOX table hub now fits seamlessly into any environment. The holder is not only sleek but also grips the tabletop securely due to the side extensions, allowing you to confidently insert your table hubs. Click - secure. The integrated locking mechanism in the ICY BOX table hubs ensures that the connection with the IB-HUBA001 never unintentionally comes loose during use.
