Garage
door torsion springs need to “match” the weight of the door. They are used to
make the door seem to be weightless, with the proper springs the door should be
able to stay at half open with out the opener attached to it. If yours doesn’t,
please contact
me.
To
insure the replacement springs are correct for your garage door, I will; weigh
your door, measure the size of your door, measure the drum size, determine if
the track arc is 12 or 15 inches and measure the current springs. With this
information I can tell you the duty cycle of your current springs and recommend
the best replacement springs, including the option of greatly increased duty
cycle springs for only a few dollars more each. This will add years of trouble
free operation for only a few dollars, and may keep you from having to replace
the garage door opener if the current springs are under sized.
If
the door has been painted one or more times it’s weight has increased. If
decorative wood has been added, its weight has likely increased dramatically.
The majority of garage doors from the factory come with 10,000 cycle springs,
which equates to opening and closing the door twice a day for 7 years before
failing/breaking.
