SKB’s injection molded Fly Rack internal frames are available to order separately in a variety of rack unit sizes and depths. These are perfect for users that already own the Fly Rack system, but would like to have additional rack frames mounted full of equipment ready to be swapped and quickly deployed. These could also be used in a studio setup where the equipment is not meant to be transported. The tops and bottoms of the frames are injection molded to stay lightweight and feature rubber feet that enable stacking to help create a modular setup. The frame has threaded steel front and rear rack rails and comes with rack screws (10-32 thread). Please see the list below to verify which additional rack frame will work with each type of Fly Rack.
