I rebuilt the upper fridge vent area in my Fiber Stream, and installed a hinged vent to access the exaust fan I installed inside. For a donation to this website, I'll send you the original.

It is a white painted aluminum panel, 23" wide by 12-5/8" tall, with 3 rows of vent louvers. There are 16 mounting holes around the perimiter.

Vent is no longer available.
