Please bear in mind that custom kits can be more expensive because we specify hardware that exceeds industry standards. You've probably heard stories of doors that fall apart after a few years. As a rough rule of thumb, you can count on paying $6.00 per pound of door weight plus an estimated $500 for shipping. For example, the hardware for a heavy 350 pound double wide wooden door could easily cost $2100 plus $500 for shipping, or a total of $2600.
Headroom is the space between the top of the door opening and the ceiling.
Vertical supports (or stiles) span across the width of the door providing stability while the door is being opened.
Nylon rollers are more expensive, and don't last as long, but are much quieter. Steel rollers are less expensive, last longer, but tend to be noisier.
The cycle life of a spring is the mathematical calculation of how many times a spring can be wound/unwound before breaking.
