Stillpoints

ESS rack

Introduced 2008$70,000 MSRP

The Stillpoints ESS (Equipment Support System) Rack is a modular, open-architecture equipment rack built around twin vertical masts connected by cross bars, with shelves suspended on steel aircraft cables rather than fixed to a rigid frame. Instead of conventional shelving, components rest on a user-selected combination of acrylic shelves, X Grids, or Rail Grids, each compatible with Stillpoints' own Ultra isolation feet, allowing the rack to be configured shelf-by-shelf for width, height, and component load while exploiting the brand's signature "suspended isolation" vibration control.
