Most Radial direct boxes, splitters, isolators and Reampers may be rack-mounted using either the J-Rak 4 or the J-Rak 8. These enable multiple units to be combined and safely stored for touring or used as part of a permanent installation. Mounting the DIs is easy. You simply remove the outer shell and slide the inner frame into one of the racks.
