A frame includes longitudinal members secured to one another. The longitudinal members support a spline that is normally open in a first position to provide a cavity. A fabric, such a mesh screen, is arranged over the frame so that the perimeter of the screen is received within the cavities of the longitudinal members. A movable platen is actuated to engage the spline. The splines are forced into the cavities to a second position in which the perimeter of the screen is pinched between a corner of the splines and the longitudinal members. A nose of the splines, which includes the corner, is retained in a channel of the longitudinal members.
