Customizing and sizing track lengths-
Typically the track length is twice the width of the door. Sizing doors in increments that work exactly with standard track length makes the process simpler such as using a 3' door with a 6' track. Using our default guidelines have the track length exactly twice the width of the door slab puts the edge of door at end of track in fully open or closed positions and also the edge of door exactly in the middle of the track in both positions.
If you are doing double doors on a single opening where each door stops in the middle of the opening with one door opening to the left and one door opening right then treat that application as two different openings where you buy one complete track kit for each door. The tracks will butt up to each other in the middle of the opening and the doors will each install and operate on their own respective track. The wheels will not pass over the joint in the middle of the opening. It is generally a better value to ship and purchase shorter length tracks like previously described. Alternatively if you want to install more than one door on a track then you can purchase the item titled "hardware kit to mount door on existing low profile mini V track"; this includes all components that come in a normal track kit except of the stick of track itself.
If your track length is going to be exactly twice the width of the door and you want the end of the track to be the edge of the door in the fully open and fully closed position you can skip ahead to step #3 now.
If you mount centerline/bolt holes of carriers 2 3/8” in from edge of dooring this will have edge of door stop flush at end of track based on predrilled stop holes in track. The stop bolt hole would drilled 1 9/16” in from end of track to center of hole. Utilizing our predetermined wood spacer block will allow for a track to work that is exactly twice the dimension of the door slab.
Here is a formula you can plug in different values if you like to calculate track length: (Door Width) + (Distance From End Of Track To Center Of Stop Bolt Hole) - Distance From Edge Of Door To Center Of Carrier) + 0.8125” = Track Length / 2
For double doors on a single piece of track just don’t divide the formula by 2 at the end.
First note is that this aluminum track is fairly simple to cut down to customized lengths. One can cut it anywhere they like with a 90 degree saw. Most wood cutting miter saws will cut this aluminum track. Use proper eye protection and safety measures. If you fresh cut an end you can touch it up with black rattle can spray paint.
To make the track function differently you can change any combination of variables such as where you mount the hangers relative to edge of door, drill stop hole in different location, or cut the track to a different length.
If your track is more than double the width of your doors and you don't want to cut it down the simplest fix is to have the end of track flush at edge of door in closed position and run the track wild or long in the open position where you will drill the one stop hole there for the door in the open position.
