We find that it is best for the customer to cut their own track during install if it is a length different than what we offer in our online store. We stock in one foot increments track from 5' to 15'. Generally we recommend purchasing the track at twice the width of the door, and always refer to our installation instructions for further tips. Sometimes a track can be adapted to work by moving the end stops or changing the spacing from the edge of the door for the hangers. If the track still needs to be cut it can easily be done at install with a hacksaw or reciprocating saw. Here are some reasons why we have learned not to cut the track to length before sending it out to the customer: our tracks are laser cut before the powder coat process so all cut tracks will have a raw exposed end. Once it is cut, that is final. If the customer measures or calculates wrong, it may be short. We have a no refund or return policy. Having the installer cut the track gives them more options; it gives you more flexibility having the extra length to work with. Most of the time, a longer track can be made to work without cutting it. Sometimes a specific right or left end should be cut. Finally, our charge to make cuts is not a good value because of our higher rates. If the customer has a large order for multiple tracks with odd sizes, has the time and budget for a custom build process, then feel free to contact us for a quote to build a one of a kind barn door hardware or extra long flat track hardware kit.
