Lomanco 189B Adjustable Foundation Vent — 16 x 8 in — Black is an all-aluminum crawlspace/foundation vent with three hinged louvers and an 8 x 8 perma-coated aluminum screen.

Lomanco lists the Model 189 family at 16 x 8 in with 74 sq in net free area; suffix B identifies the black painted finish in distribution records. Use foundation ventilation as part of the project's overall moisture-control and code strategy rather than assuming one vent size/count fits every crawlspace.
