Sound Barrier SB4USMRX Anti-Shock Rack Road Case — 22-Inch Depth with EVA Foam Protection
SB4USMRX Overview
The Sound Barrier SB4USMRX is a professional anti-shock rack road case built for the rigors of touring, live production, and equipment transport. Constructed with 12MM thick premium wood board set within custom-made aluminum profiles, the case surpasses the structural integrity of conventional chassis designs that rely on pull studs. The upper and lower aluminum profile joints are secured via aluminum welding, while the internal fixed structure frame uses 5MM iron plates bonded with high-strength shock-absorbing glue, delivering a fully loaded transport solution that resists the compounding stresses of road use. This case is designed for touring companies, system integrators, broadcast facilities, and venues requiring dependable rack protection in transit.
The captive pocket door design and dual front-and-back rack strip configuration allow for efficient equipment access and secure racking, while the full-size caster board and high-elasticity wheels make repositioning loaded cases practical in stage and venue environments.
