Frequently Asked Questions
What makes the rSeries Shock Rack different from standard rack cases?
The SKB rSeries Shock Rack features a proprietary Roto Shockmount system with elastomer shock absorbers positioned at all eight corners. This design creates sway space around the internal frame, providing three-axis shock protection that standard cases cannot match. The shock isolation technology protects equipment from impacts during transport while maintaining natural air circulation for cooling.
Is the 4U 20-inch deep rack case suitable for touring and mobile applications?
Yes, the SKB 4U 20-inch Deep rSeries Shock Rack is specifically engineered for touring, broadcast, and mobile production environments. Its rugged construction, shock isolation technology, and standard rack rail compatibility make it ideal for professionals who transport sensitive equipment regularly. The case protects gear from vibration, impact, and environmental stress during travel and setup.
What equipment can fit in a 4U rack case with 20-inch depth?
The 4U rack configuration accommodates four rack units of standard 19-inch equipment, with 20 inches of depth for components like audio processors, amplifiers, network switches, and broadcast equipment. The generous depth allows for proper cable management and airflow. Verify your specific equipment dimensions against the internal space to ensure compatibility.
How does the shock isolation system protect equipment during transport?
The Roto Shockmount design uses elastomer shock absorbers to isolate the internal rack frame from external impacts on three axes. When the case experiences shock or vibration during transport, the elastomer absorbers compress and dissipate energy, preventing that force from reaching your equipment. This three-axis protection is superior to rigid cases for sensitive gear.
