Rackmount Cases Explained (Sizes, Shockmount vs Hardmount Guide)
Rackmount cases are specialized protective enclosures designed to securely transport, store, and operate rack-mounted equipment such as servers, audio/visual systems, communications gear, and military electronics. These cases are built to standard rack dimensions and provide structural support, protection from shock and vibration, and organized equipment integration.
At Cases2Go, we engineer complete rackmount case solutions by combining rugged outer cases with custom foam inserts, shock isolation systems, and precision mounting hardware to ensure your equipment is protected and deployment-ready.
Types of Rackmount Cases
Choosing the right rackmount case depends on how your equipment will be used, transported, and protected. The three primary types of rackmount cases include:
Shockmount Rack Cases (Best for Transport)
Shockmount cases are designed for frequent transport and harsh environments. These cases utilize elastomeric shock absorbers or internal suspension systems to isolate the rack frame from external impact and vibration.
- Ideal for military, field operations, and mobile deployments
- Protect sensitive electronics from shock and vibration
- Commonly used for communications and AV systems
For maximum protection, shockmount cases are often paired with engineered foam interiors to secure individual components.
Hardmount Rack Cases (General Use)
Hardmount rack cases feature a fixed rack frame that is directly mounted to the case structure. These are best suited for applications where equipment is transported occasionally or remains mostly stationary.
- Cost-effective solution for lighter-duty applications
- No internal shock isolation system
- Ideal for controlled environments
Rack Enclosures (Stationary Applications)
Rack enclosures are designed for stationary environments such as server rooms, studios, and office installations. These enclosures prioritize accessibility and organization over transport durability.
- Best for permanent or semi-permanent setups
- Minimal need for transport protection
- Common in IT and broadcast environments
Standard Rackmount Dimensions (19" Rack Width)
Most rackmount equipment is built to the EIA-310 standard, which defines a rack width of 19 inches (48.26 cm). This standard ensures compatibility across a wide range of equipment and rackmount cases.
Understanding rack dimensions is essential when selecting the correct case for your equipment.
What is a Rack Unit (U Size)?
Rack equipment height is measured in rack units, commonly referred to as “U”. One rack unit (1U) equals 1.75 inches (44.45 mm) in height.
- 1U = 1.75 inches
- 2U = 3.5 inches
- 5U = 8.75 inches
Rackmount cases are labeled based on the number of rack units they support—for example, a “5U rack case” or “3U rack drawer”.

Key Considerations When Choosing a Rackmount Case
Selecting the right rackmount case requires careful evaluation of your equipment and application:
- Rack Depth: Ensure the case accommodates the full depth of your equipment, including connectors and cabling
- Shock Protection: Determine if your application requires shockmount isolation
- Weight Capacity: Heavier equipment may require reinforced structures
- Rear Mount Rails: Additional support may be needed for deeper or heavier components
- Transport Conditions: Consider whether the case will be used in field operations, shipping, or stationary environments
For equipment that requires additional protection, combining rackmount cases with custom foam inserts can provide enhanced security and organization.
Rackmount Cases vs Transit Cases
While both are designed for equipment protection, rackmount cases and transit cases serve different purposes:
- Rackmount Cases: Designed to house mounted equipment within a structured rack system
- Transit Cases: Designed for general equipment transport with custom foam interiors
Many applications combine both approaches—using rackmount cases with additional foam cushioning for maximum protection.
Industries That Use Rackmount Cases
Rackmount cases are widely used across industries where equipment organization and protection are critical:
- Military & Defense
- Broadcast & Audio/Visual
- IT & Data Centers
- Telecommunications
- Medical Equipment
For specialized applications such as mobile communications units, rackmount cases provide both protection and operational functionality.
Frequently Asked Questions About Rackmount Cases
What is the difference between shockmount and hardmount rack cases?
Shockmount cases include vibration isolation systems, while hardmount cases have a fixed rack frame with no shock absorption.
What does “U” mean in rackmount cases?
“U” stands for rack unit, where 1U equals 1.75 inches in height.
Are all rackmount cases 19 inches wide?
Yes, most rackmount equipment follows the standard 19-inch width defined by EIA-310.
Can rackmount cases be customized?
Yes, Cases2Go offers custom rackmount solutions including shock isolation, foam interiors, and integrated configurations.
