If you buy a cheap "19-inch rack" from an unknown manufacturer, you can use the standard to check:
The spacing between holes in a 1U group follows a repeated pattern: . Horizontal Widths: Mounting Flange Width: Minimum of 19 inches (482.6 mm) .
Used with clip-on nuts or proprietary toolless rail kits.
Nora leaned back in her chair, the dusty Chicago sunlight cutting across her home office. EIA-ECA-310-E. She hadn’t thought about that document in thirty years. Back when she was a young engineer at a defense subcontractor, she’d spent six months helping rewrite the mechanical standards for electronic equipment cabinets—the steel skeletons that held sensitive military gear. The "E" revision was her baby. She’d argued for three extra millimeters of airflow clearance. She’d watched a prototype survive a simulated 8.4 magnitude shaker table test. Eia Eca-310-e Pdf
The distance between the centers of the mounting holes on the rails is 18.312 inches (465.1 mm) .

It is important to note that this is a voluntary standard. No governing body enforces compliance, and it is up to the manufacturer to build their cabinets in accordance with it. This is why you will see many products labeled as "EIA/ECA-310-E compliant" or "EIA-310 compliant," indicating that they are designed to meet the standard's mechanical requirements.
Typically #10-32, #12-24, or M6 threads tapped directly into the metal rail. These are common in telecom (2-post) racks and AV environments. Why Compliance with EIA-310-E Matters Nora leaned back in her chair, the dusty
: The "E" revision, released in December 2005, is the most recent update, following the widely known EIA-310-D.

"Transmission complete. Deleting source personality to save space. Goodbye, future."
Servers, UPS systems, and networking gear from different vendors can be installed in the same cabinet.
The inner opening width between the rack rails must be at least 17.75 inches (450.8 mm) to allow the chassis body to slide into the rack. 3. Mounting Hole Types
