Adapter Fit

Same cooling capacity and voltage as the G520816G150. Cabinet cutout dimensions differ, so an adapter plate is required to bridge the mounting pattern between the existing opening and the VoltAire AT08RMW07 — so you're not fabricating a new opening. Plan on some fitting work during the swap; we'll spec the exact adapter for your installation at order review.
