Compatible Float Box
When standing at the front of your evaporator, this style float box is mounted on the right side. This Float Box lid is notched to accommodate the Float Box hanger on that side. This style float box is found on Dauntless Drop Flue Pan Sets and also some custom hybrid pans.
Alternatively, if your float box hangs on the left side of the evaporator, you would need lid model SL-LIDINBXL. That lid is notched on the opposite side to accommodate that Float Box hanger.
