Best Torsion Spring Deal For The Normal Person
Most people expect their springs to last a few decades.
These springs will do that.
They are rated for over 50,000 cycles and should last most active people over thirty years.
Typically 1,000 cycles last a person 1 year.
However your mileage may vary.
For instance today I replaced springs that were rated for 22,000 cycles after they had been in use for 7 years and 10 months.
All the better to have springs rated for over 50,000 cycles.
Yes, I beat any quote in Menifee by $10 on these springs too.
However it is based on cylces per dollar since it is highly unlikely my competition will be using the exact same springs as me.
To calculate the cycles per dollar you need the dimensions of the old springs or the weight and height of your door.
(It is best to know both so you can verify they agree.
It is like solving a formula and then putting the answer back in to verify.
The springs dimensions should match the weight and height of your door or something is off.
Use the following table link to verify.)
With either or both of those two metrics you can call about asking for the springs each garage door company would use for your door.
Then use this table to determine how many cycles those springs are rated for.
Divide those cycles by the total cost and if it is a better deal I'll match that ratio and give you $10 off.
And if any of your neighbors mistakenly buy their springs from somebody besides me, within a year of your purchase, I'll retroactively pay you back the difference.
My prices for these 50 thousand cycle springs are usually lower than what my competition charges for their 10 thousand cycle springs.
The $219 is to replace the two springs in a normal two car seven foot high garage door regardless of its weight.
That includes tax, labor, springs, and usually a tune-up on the door.
(Often garages are so full we can't do a normal tune-up.)
So how do I beat my competition by $10 or possibly much more?
I buy in large quantities directly from the manufacturer.
I have no overhead.
I don't waste my time driving and instead stay local within Menifee.
(Though I do sometimes go to the surrounding cities if work is slow but then I don't guarantee the prices being the cheapest and also reserve the right to charge more.)
I use a combination of five different 50,000 cycle springs depending on the weight of the door.
In the following table those five are in bold italic.
The gauge, or thickness of the spring, are the column headers.
The length of the 1.75 inch inside diameter springs start the left most column in purple.
Then the column doubles its usage and includes 2 inch inside diameter springs.
The industry uses color coding to visually mark the thickness of the spring.
Often the colors have worn off.
However I used the standard colors in the table just in case they are still marked.
The cell to the left is the thousands of times the door can be lifted before it is expected to break.
The cell in the same color to the immediate right is the weight it will lift at 7 feet.
So for light doors I might use a .207 inch thick spring, with an inside diameter of two inches, and a length of 27 inches.
That would give me a spring that would last 80,000 cycles and lift a door that weighed 68 pounds if the spring were turned 7 complete revolutions.
Or 58,000 cycles and lift 73 pounds if turned 7.5 revolutions.
