The spline channel includes a bottom wall having two end walls extending upwardly therefrom and terminating in inwardly extending lips. One of the lips extends further inwardly than the other of the two lips. The spline includes opposite side edges, one of which is forced into the recess beneath the longest lip so as to force the screen into the recess between the spline and the end wall of the channel. The opposite edge of the spline is then pressed downwardly until it snaps into the channel and holds the screen in place.
