Sound Barrier SB33UMB18 33U Anti-Shock Rack Road Case — 18 Inch Depth
SB33UMB18 Overview
The Sound Barrier SB33UMB18 is a 33U anti-shock rack road case built for professionals who demand maximum equipment protection during transport and touring. Constructed with 12mm thick premium wood board set within a custom-made aluminum profile, this case surpasses the structural integrity of conventional chassis designs that rely on pull studs. The internal fixed structure frame uses 5mm iron plates bonded to the case body with high-strength shock-absorbing glue, and all upper and lower aluminum profile joints are secured by aluminum welding for a rigid, road-worthy assembly. This case is purpose-built for touring companies, system integrators, broadcast facilities, and venues requiring reliable rack protection under the demands of repeated loading and transit.
Captive pocket doors, a full-size 18mm plywood painted caster board, and 4 x 4-inch high-elasticity caster wheels with two safety brakes make the SB33UMB18 practical for stage-side deployment and backstage positioning without sacrificing structural integrity.
