The lock pin assembly comprising an elongate connector strip having first and second major opposite surfaces, a plurality of lock pins joined to the first major surface, and connectors joined to the second major surface for connecting the lock pin assembly to the frame. The lock pins includes devices for interlockingly and removably engaging the attachment apertures to maintain the positioning of each screening or diverting module on the frame when the lock pin assembly is attached to the frame. The lock pin assembly remains connected within at least one mounting aperture of the frame while allowing removal of a screening or diverting module from the frame and positioning of a replacement screening or diverting module on the frame.
