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.

2 * Anti-jumpers- those little round discs- go on top of the door and wont allow door to be lifted off rail unless theyre turned.

Q: When do you need a headboard?

a. If the studs dont 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 5" 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 youre 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.
