Our rail is made by 1/4 heavy duty carbon steel, solid inside, frosted black surface. The rail comes in two pieces, instead of mutiple small pieces, the door can roll quietly and smoothly. OVERLAP SPACE? There would be a 8″-12″ overlap space since the 2 doors are hanging on one single rail. The door panel width should be wider than half of the (opening+overlap sapce) or the opening may not be fully covered. EASY TO INSTALL? Professional instruction and customer service team help you solve all installation problems in time. Save the cost of finding a Carpenter or decoration team. PACKAGE INCLUDED? 2x Rail, 4 x Hanger, 5 x Wall spacers, 1xFloor Guide, 2xDoor Stoppers, 2x Hex Key, and other necessary hardware is included as you see in the pictures. DOOR WEIGHT CAPACITY? Door Weight Limited 220lbs. Fit door panel thickness: 1 3/8″ to 1 3/4″. Q: How to ensure the stability and safety of the door? Two door stoppers slide along the rail and tighten down at any point to stop your door exactly where you want, and they’re cushioned by rubber caps for a quiet close. A T-shaped floor guide is supplied (with anchors) to prevent the door from swinging out or up against the baseboard. Q: When do you need a headboard? If the studs don’t line up with the pre-drilled holes in the rail. If there is a doorway trim. Q: How much space do I need above the doorway? A: You will need a minimum of 6 from the top of your door to the ceiling (or crown molding, if any) for this kit to fit correctly. Q: How thick of a door will this kit work with? A: There are solutions for any thickness of door! The bolts included for attaching the hangers to the door support a thickness range of 1 3/8″ to 1 3/4″, but this can be easily navigated by countersinking the bolt head into the back side of the door, or by picking up 4 longer bolts from your local hardware store. The other thing affected by a thicker door is the spacing needed between the door and wall (or baseboard/doorway trim). Plug in your door depth and trim depth below. 2”- door depth – trim depth. If your answer is 0 or greater, then you’re fine. If your answer was negative, then that number is the extra spacing you need. This extra spacing is accomplished by bolting a header board to the studs, and then the rail to this header board. We offer the best prices around on high quality products.
