Here s a complete guide to high lift conversions for the standard garage door.
A high lift garage door extends your garage door s track so that the door hugs the wall and goes up higher before the horizontal curve.
It makes better use of the vertical space in your garage and gives you at least 12 15 more headroom in your garage by moving the garage door track closer to the ceiling.
If you need a shaft to convert to a high lift system we recommend buying a shaft locally from a steel supply center or a steel scrap yard.
The cable drum should be cast on an aluminum alloy and it should have an end bearing plate just beyond it.
This form will follow the first two sections of our high lift garage door conversion tutorial.
The cable drum can be found after the end of the spring assembly.
1 divide the total spring s ippt by the cable drum multiplier 2 multiply the spring ippt by the number of turns and then divide by the hi moment arm high lift.
High lift kits increase the vertical rise of the garage door so that the door reaches the horizontal track closer to the ceiling than with a standard lift garage door.
Measure the distance from the top of the closed door to the bottom of the horizontal track.
