Blackbird Carts Grackle Add-On 4U Equipment Box

Need some rack space on top of your Grackle equipment box? This 4U rack case mounts solidly to the top of the box for rack shelves, drawers, PSC or Remote Audio power supplies, or any other standard 19" rack equipment. 

Note: This 4U box hangs over the Grackle's storage box about 3 inches on either side but still within the footprint of the rear wheels.
