Wood Vent Jamb Extension Kit, Standard Size

The wood venting octagon jamb extension kit is designed to be applied to the interior jamb of the standard size unit extending the depth from 4-11/16″ up to 6-11/16″. The kit contains 8 pieces clear Pine measuring 1-1/4″ thick x 2″ deep and is mitered on both ends to match the size of the octagon window.

The wood parts of the kit are shipped unassembled so they can be trimmed to match your exact wall thickness.
