For a multi-fold unit to fit and function properly you must not forget to add the height of the track and hardware to the door height. This additional height should be found and reviewed in the installation instructions of your chosen track and hardware before purchasing your doors. Here is an example, one type of track calls for an additional 2 7/8” to be added to the door height for proper operation, if you are using an 6/8 (80”) door, the height measurement for your opening should be 82 7/8”. Depending on the width of the opening, door sections of 12”- 36” can be used in most cases. Once again, the type of track and hardware that you select will dictate the number, size, and weight of doors that can be used. Also instructions should be consulted for the additional width that will need to be added to the opening to insure a good fit and smooth operation.

   Most available track and hardware will limit you to no more than six doors sliding in each direction. Although an even amount of doors must be configured on both sides, the number does not have to be the same as long as it is even. Two sliding to one side and four sliding to the other side, or four to one and four to the other side, as long as you do not exceed six sliding to one side you control the setup.

   Be sure to first investigate the track and hardware instructions carefully before attempting installation and even before ordering your doors. A large opening can be filled with a beautiful multi-fold door application but careful planning must be done as the margin for error is minimal.
