ABSTRACT:
A fence with hollow posts and rails uses a flexible plug that is placed in insect entry path blocking position by sliding the plug into a fence rail in a direction that is perpendicular to the longitudinal axis of the plug. A friction fit between shoulders on the plug and a rib and ledge inside of the rail is attained by the relative spacing of the shoulders to the spacing of the rib and ledge.
