Abstract
A shutter and retention assembly of modular members molded or extruded from a polymeric material includes a pair of side rails, each side rail having a front wall, an outer wall and an inner wall. The inner wall includes a retaining channel formed therein. The shutter further includes a shutter panel member having a central portion and a pair of runners extending along the sides thereof. Each of the runners includes a projection extending along at least a portion thereof. The projection has a cross-sectional shape complementary to the retaining channel of the side rails for securing the panel member to the side rails. The complementary shapes of the engaged projections and retaining channels resist disengagement of the side rails from the panel member.
