Abstract
The invention relates to a sealed duct vehicle cab post. A cab frame includes a hollow cab post having an air vent in a sidewall thereof and open first and second ends. A piece of unexpanded foam is attached to a clip. The clip has a base forming a foam piece support to which the piece of unexpanded foam is attached. The clip has a gripping member, and an arm connecting the base to the gripping member. The clip and the foam piece are inserted through the vent and into the post so that the unexpanded foam piece is inside the post and spaced apart from an edge of the vent and between the vent and the first end of the post. The gripping member is coupled to the post so that the gripping member grips, an edge of the vent. The cab frame and/or the post is then heated so that the foam expands and forms a seal within the post between the vent and the first end of the post. The result is a cab post with a sealed lower end wherein conditioned air from a roof mounted HVAC unit will flow from the upper end of the post, through the post to the vent and out of the vent and into the interior of the cab.
