<p>An adjustable length shutter assembly of molded plastic modular construction comprising a pair of side rails which may be cut to desired length, one or more shutter panels slidably received within parallel doublechannel tracks extending along the opposing side rails, and upper and lower end rails extending between the side rails and capturing the shutter panels in assembly. In a preferred embodiment of the invention, at least two shutter panels are carried between the shutter side rails and are separated from each other by a mullion piece. In accordance with one important feature of the present invention, the end rails and the mullion piece are so constructed as to overlap the edges of the side rails and shutter panels which are adapted to be adjustably trimmed during the installation process so as to reduce fading and structural deterioration at the cut edges due to exposure to ultraviolet solar radiation. Another feature of the invention contemplates an improved structural connection between the end rails and side rails, which not only overlaps the cut edges of the end rails as previously described, but also enhances structural rididity of the overall shutter assembly during and following installation.</p> |
