Q: How to ensure the stability and safety of the door? 2 * Door Stoppers: 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. 1 * Floor Guide: 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? a. If the studs don't line up with the pre-drilled holes in the rail. b. If there is a doorway trim. And "door depth'' plus "trim depth'' is greater than 2'' 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.
