Made of low-maintenance and long-lasting fiberglass-reinforced concrete, the new Deckorators cast-stone post covers come in three styles—gray fieldstone, gray cobblestone, and gray stacked stone—with five mix-and-match post caps. The post covers work equally well with wood, composite, or vinyl railings. Each cover slips over a 4x4 or 6x6 cedar or treated post, measures 8 inches square, and comes in 42- and 53-inch heights. Post covers can also be stacked to create robust stone-look columns. Deckorators, 800.332.5724,
