The interior space between the mounting rails must be at least 17.75 inches (450 mm) . Front Panel Width: Standardized at 19 inches to match the flange. 🛠️ Hardware & Installation
Used with clip-on nuts or proprietary toolless rail kits.
17.75 inches (450.8 mm). This is the maximum physical width of the chassis body that slides between the rack rails. 3. Mounting Hole Types
The EIA ECA-310-E standard is widely used in various industries, including: Eia Eca-310-e Pdf
To ensure that equipment from various manufacturers fits securely and correctly into standard racks and cabinets.
The (Cabinets, Racks, Panels, and Associated Equipment) is a technical standard developed by the Electronic Components Industry Association (ECIA) and the Electronic Industries Alliance (EIA). It sets the rules for the 19-inch rack mounting system, which is the universal standard for mounting electronic equipment.
: Often used with specific proprietary rail kits or older equipment. Why Version "E"? The interior space between the mounting rails must
Bottom hole to the top hole of the next U: 0.500 inches (12.70 mm) 2. Standard Widths
The standard focuses on four critical spatial areas to ensure universal compatibility: One Rack Unit (1U) is exactly 1.75 inches (44.45 mm) high.
: The current revision, which primarily includes minor grammatical updates and clarifications over the "D" version. Accuris Standards Store Compliant Product Examples Mounting Hole Types The EIA ECA-310-E standard is
It is often referred to simply as the "19-inch rack standard," although it covers much more than just width, including vertical spacing, hole patterns, and material requirements to ensure equipment from different manufacturers is compatible. Electronic Industries Alliance ECA: Electronic Components Industry Association 310-E: The revision level of the standard. Key Specifications of EIA/ECA-310-E
While the EIA/ECA-310-E standard is dominant in North America, other countries use equivalent standards. The most notable is , an international standard with nearly identical mechanical specifications. In Germany, the DIN 41494 series of standards accomplishes the same goal.
Like any good building code, EIA/ECA-310-E defines the vital framework but leaves room for innovation.
