Up to 4,000 mmForce
Up to 200TQuality
FAI AvailableControl the interfaces
The rack ears are only the beginning
Reliable installation depends on the full chain of dimensions from the mounting face to rails, handles, connectors and internal assemblies.
Width and ear alignment
Rack opening, flange flatness and hole position managed to a functional datum.
U-height discipline
Panels, seams and fasteners kept inside the installation envelope.
Rail load path
Internal weight transferred through formed features and reinforced attachment points.
Rear I/O registration
Cutouts remain aligned after bending, welding and finishing.
Configuration freedom
Specify the chassis your application needs
Front panel
Displays, switches, handles, branding, filters, locks and service indicators placed to your drawing.
Internal architecture
Card guides, PSU brackets, motherboard trays, partitions and cable tie points integrated into the build.
Access and cooling
Removable covers, fan panels, vents and filters designed for field use and production assembly.
From one prototype to a controlled product family
A shared chassis architecture can support multiple SKUs without forcing every configuration into a unique tooling program.
Discuss a modular platformReuse structural parts across variants.
Change rear or front panels by SKU.
Maintain brand consistency.
Control options without redesigning all metal.
Production confidence
Inspection follows how the chassis is used
Not every dimension carries equal risk. At Hengtai Leading Technology, we build the inspection plan around rack fit, board location, panel appearance and mating interfaces.

Rackmount Standards Explained
EIA-310 defines the familiar 19-inch rack interface, including rack-unit spacing and mounting geometry. Product depth, rail engagement and front-panel projections still require application-specific control.
| Rack size | Nominal height | Typical use | Mechanical watchpoint |
|---|---|---|---|
| 1U | 44.45 mm | Network and compact compute | Fan height and panel flatness |
| 2U | 88.90 mm | Servers and appliances | Riser and PSU packaging |
| 3U | 133.35 mm | Instrumentation and storage | Internal card retention |
| 4U | 177.80 mm | GPU and industrial systems | Loaded weight and rails |
| 5U | 222.25 mm | Specialized electronics | Panel stiffness and handles |
| 6U | 266.70 mm | Large modular platforms | Frame squareness and lifting |
