With all the same features as the RC series and then some, OSPs SC shock-mount rack cases feature a 1" wall of heavy foam between the outer wall and inner walls where the rack rails are mounted. They also feature egg-crate foam insulation on both the front and back doors for added protection of your rack gear. Protect your investment with the SC4U-14 that provides a 4-space rack compartment at 14" depth. For over a decade, OSP has been providing quality cases for affordable prices. Whether youre rolling into a different arena every night, setting up and tearing down a portable church every Sunday, or simply taking your amp across town for this weeks gig, youll find an OSP case to be a perfect companion for keeping your gear safe during transport.
