Chassis Dimensions — Specifications & Guides

A standard chassis refers to an enclosure built to EIA-310d specifications, designed for use in a 19-inch rack system. Ron Nunes Enterprises' standard chassis features a 17-inch panel width, heights from 1U to 9U, and depths of 8, 14, 20, or 26 inches. It includes front and rear panels, side brackets, covers, handles, and all assembly hardware.

In the context of rack mount chassis, a common configuration with approximately 20-inch depth features a 17-inch panel width designed for 19-inch racks, with heights ranging from 1U (1-3/4 inches) to 9U (15-3/4 inches). Ron Nunes also offers 20-inch depth slides rated at 175 lbs per pair for mobile and field deployments requiring shock and vibration resistance.

Ron Nunes rack mount chassis are available in heights from 1U (1-3/4 inches) to 9U (15-3/4 inches). Additional non-standard heights of 17-1/2 inches, 19-1/4 inches, and 21 inches are also available. Custom heights can be requested through the engineering team for OEM and specialty applications.

Primary chassis components are fabricated from 0.125-inch thick Aluminum Sheet, Alloy 6061-T6, conforming to QQ-A-250/11 and ASTM B209. Chassis plates use Alloy 5052-H32. Handles are extruded aluminum Alloy 6061-T5. Stainless steel options are also available. Military-grade MIL-C-5541E Type I Class 3 gold chemical film finish is the standard surface treatment.
