Springs are used on garage doors as a counter balance to compensate for the heavy weight. Making operation by the manual user or garage door opener unit possible. When a spring breaks. The garage door will not open with normal operation and all springs should be replaced. The new springs used must match & equal the specifications required to operate the door. Every door has a specific spring. It is calculated by weight, height, mass of the door & track radius, type lift of cable drums. The manufacturer will provide with the new door, the correct spring needed to operate that door. Any future springs replaced should match the original equipment specified item. Springs are loaded and should be handled by qualified persons and extreme safety measures should be advised. There are many types of spring systems designed for garage doors.

Helpful Formulas & Rules For Calculating Springs

Spring Length = Number of coils x wire size. Example: 100 coils x .250 wire = 25"

Determine ID  = Subtract the wire size twice from the OD of a spring. Example: 2 1/2" OD spring with .250 wire) 2 1/2" - .250 - .250 = 2" ID

Torsion:

Amount of Spring Growth = Number of turns x wire size. Example: 10 turns x .250 wire = 2 1/2" of spring growth

Wire Size = Inches divided by the number of coils. Example: 2 1/2" per 10 coils, 2 1/2" divided by 10 = .250 wire

Door Weight = Total IPPT of a door's springs divided by the cable drums multiplier

CAUTION: SPRINGS OPERATE UNDER EXTREME TENSION & CAN CAUSE BODILY HARM.
