High Lift Garage Door Track

High lift garage door track is used to maximize the headroom above sectional overhead doors. Unlike standard lift track which curves back horizontally just above the opening, high lift track lets the door travel further vertically. High lift garage door track frees up a lot of space. This is useful for residential and commercial buildings where overhead doors in the open position are in the way.

Overhead doors are easily hit with fork trucks and other equipment in commercial applications. Storage facilities and warehouses that don’t utilize high lift track may find themselves routinely replacing garage door panels. Although a high-lift conversion kit may cost you money upfront, it will likely save you or your company in the long run. The main advantage to high lift track is the ability to maximize the space that was wasted by not getting a taller garage door.

Calculating Maximum High-lift

Finding the correct amount of high-lift track to install is fairly easy to calculate. Since the spring line on a high lift assembly uses about 12 inches of space we need to subtract that amount from our high-lift garage door track calculation. High lift applications use special drums that are much larger than standard lift drums in most instances. If you don’t give the drums enough space they will scrap against the ceiling during operation. The formula for calculating the maximum amount of high lift you can use is (Floor to Ceiling Height) – (Rough Opening Height) – (12 inches) = (Maximum High Lift)

  1. Measure from the floor to the nearest obstruction on the ceiling (ex. 144 inches)
  2. Measure the rough opening height of your door (ex. 96 inches)
  3. Subtract 12 inches from that figure to account for the spring line (144-96-12=36 inches)
  4. The most high lift you can use in the example above is 36 inches or 3 feet of high lift.

What Type of Garage Door Opener

Since high lift garage door track makes the door move up the header further before curving a standard garage door opener will not work. The rail or beam of the operator would bolt into the header and block the door from raising. Jackshaft motors avoid all of this trouble by mounting on the side of the door. High lift track applications require manual operation or jackshaft side mount operators.

The minimum recommended space to install highlift track is 24-inches. If you have less than 24 inches of space use 15-inch or 18-inch radius track instead of highlift. Installing less than 12 inches of high lift track is a waste of time and money. High lift kits range in price by the size of the door and amount of highlift that must be installed.  Call your local garage door dealer for a custom quote on this type of conversion.
