Pre-Fabricated Corners
Pre Fabricated corners are available only for the SM5-ST. These corner pieces are suited for either a 90 degree inside or outside corners. They are recommended for the first time installer, do-it-yourselfer or anyone who is not comfortable or familiar with a miter saw. Unlike other pre-fabricated corners you may be accustomed to, these corners overlap the molding rather than butt up against it.
Over-lapping offers many advantages: They allow 1/4 of tolerance when cutting trim; if the trim shrinks, the overlap will hide the gap; some find it to be a more interesting look as well.
