The track length should be twice of your door or opening. For example, if you have one door that is 4FT wide. You will need 2 x 4FT = 8FT long track. Or if you have a opening that is 5FT wide, you will need the 10FT long track. Yes, the rail can be cut to any length. We recommend using an angle grinder to cut the rail. 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. If the pre-drilled holes in the rail don’t line up with your wall studs. 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.
