Yardcrafters Vinyl Railing Systems provide a maintenance-free alternative to pressure-treated wood. It's an economical solution for homeowners tired of yearly upkeep. Trade in your sanding equipment, paint brushes and hammers for a garden hose. Simply wash down the railing and spring improvements are done. This 4" x 4" x 96" square post wrap, which acts as a sleeve over 4 x 4 lumber, will never need painting, staining or sealing to keep its good looks. It won't fade or yellow, crack, split, splinter or peel like wood and always looks freshly painted.
