Next page How do I know the length of track I need for my opening? The track length should be (your door opening +24 inch). Then there will be 1/2 opening to allow your walking. And if you need to see larger opening,you will need to choose longer track size. How to prepare my doors? We suggest your each door width is MIN (1/2 opening +7 inch). It could cover your opening better! Can I cut the rail to fit my wall? Yes, the rail can be cut to any length. We recommend using an angle grinder to cut the rail. What is the compatible door thickness? 1-3/8"～1-3/4". Note: If you have door thickness that falls out of this range, please let us know your exact door thickness so that we can put shorter hex bolts for your thinner doors or longer hex bolts and spacer extenders for your thicker doors. When do I need a headboard?? a. If the pre-drilled holes in the rail don't line up with your wall studs. b. If there is a doorway trim. Attach a header board with the same thickness as your doorway trim into your studs first, and then mount the rail onto the header board.
