Independent shopping perspective
Use the Radial Engineering Solo filler panel to cover an open double-wide space in a Radial Workhorse or another 500 series rack. It closes off the unused area to help keep dust and other contaminants out, while adding a protective barrier over the rack opening. It is a straightforward rack-maintenance part for keeping an unoccupied slot covered.
