Behringer 3U Rack Mount Brackets for Modular Synths.

Several 3U rack ends 'ears' - the larger 'ears' for the WASP, CAT, MODEL D etc. with holes for MIDI and USB leads.
Shorter 3U rack ends for the K2, KOBOL, PRO-1, MODEL 15, NEUTRON etc. These have been designed with the intention of removing the wooden ends of the synths and using the existing screws to attach them (leaving the metal end plate in place)
