thanks for the reply tom. Problem is all ive been finding is basically 14x14 replacements. the inside opening is basically 19-1/2". i would then have to fabricate a 24x24 roof plate an cut out hole for 14x14 vent. then garnish an clean up, trim out an finish the inside to look presentable.

thinking about putting a 22" escape hatch vent. or a hatch used on boats. alot of marine hatches to choose from.

ended up orderding a lewmar low profile deck hatch. size 60. cutout made for a 20x20. update over the weekend, if it ever stops raining...
