air extractor for asw19 and asw20
I didn’t cut the holes, but mine has a fold down wood bulkhead with a pretty gap (about 1/2 inch) around the perimeter. That gap was large enough that I though I’d give it a try before cutting the holes. I was happy with the result, so I’ll probaby not cut the holes. The fiberglass bulkhead has a tighter fit, so you may ne d the holes.
