## Description

Door Only - Rail Hardware Kit Sold Separately from Industrial By Design  Measurement Detail: Door width (assembled): 36" Door height (assembled): 84" Door thickness: 1 3/8" Board width (outer perimeter): 4" Board width (inner vertical planks): 5 1/2" Board width (inner diagonal planks): 4" Bottom channel groove: 5/8" deep x 1/4" wide   Material & Finish:  Only 100% high-quality Alder is used in our barn door kit, which results in a more attractive wood grain, a heavier and sturdier door, and a harder finished product than the cheaper and less durable Pine alternative. One sanded coat of varnish has been applied to prevent warping or cracking while shipping. Your barn door arrives ready for stain, paint, or a final clear coat.    Assembly:  Included is our easy Step-By-Step video to simplify assembly. Our experienced customer service team is U.S. based and quick to respond to any questions.
