Is in Extension Spring Color Chart Alles wat jo wirklik nedich binne?

Jo garaazjedoar spring is brutsen, en in kleurkaart liket in maklike fix. Mar allinich fertrouwe op kleur kin liede ta it kiezen fan 'e ferkearde maitiid, it meitsjen fan in serieus feiligensgefaar foar jo famylje.

An extension spring color chart is a guide that links your garage door's weight to a specific spring strength, identifisearre troch kleur. Dit systeem helpt jo in ferfanging te finen dy't de doar goed balansearje sil, but it's only accurate if you know your door's true weight.

I've been manufacturing springs for over 14 jier, en ik kin jo fertelle dat in kleurkaart in ark is, gjin oplossing. Ik haw ienris wurke mei in ynstallaasjebedriuw foar garaazjedoarren dat konstant klachten krige oer doarren dy't net goed slute. It die bliken dat har technici krekt oerienkomme mei de kleur fan 'e âlde maitiid doe't se ferfangings diene. They weren't weighing the doors. Nei jierren fan bleatstelling oan de eleminten en in pear nije lagen ferve, in protte fan 'e doarren wiene 20-30 pûnen swierder as doe't se nij wiene. De âlde boarnen foelen al ûnder de spanning, en ferfange se mei deselde "kleur" wie krekt it probleem werhelle. That's why you have to look beyond the color and start with the facts.

Why Is Your Door's Weight More Important Than the Color Code?

Jo fûnen de kleur op jo âlde maitiid, mar wat as it al ferkeard wie? Gewoan oerienkomme mei dy kleur betsjut dat jo in undersized maitiid kinne ynstallearje, liedt ta in oare mislearring en in ûnfeilige doar.

The color code is just a label for a spring's lifting power, which must match your door's actual weight. Doors get heavier over time. Weighing your door is the only way to guarantee you select the correct spring for safe and balanced operation.

In our factory, every spring we produce is calibrated to a precise force specification, which is then represented by a color. But that color is meaningless without the correct starting number: the door's weight. People often skip the weighing step because it seems like a hassle. They assume the last person did it right. But I've seen homeowners add heavy insulation panels or even decorative hardware, adding significant weight to a door. The original springs were never designed for that load. Without weighing the door, you are flying blind. Taking 15 minutes to get an accurate weight is the single most important step in ensuring the repair is done safely and correctly. It removes all guesswork and is the foundation of a properly balanced system.

The Correct Weighing Procedure

This is a safety-critical process that must be done carefully.

• Step 1: Disconnect Power. The very first step is to unplug your garage door opener from the electrical outlet.
• Step 2: Disengage the Door. Pull the red emergency release cord to disconnect the opener from the door.
• Step 3: Weigh the Door. With the door fully closed, place a standard bathroom scale under the left side and another under the right side. You may need small blocks of wood to lift the scales up to the door's bottom seal. The combined reading of both scales is the true weight of your garage door. Dit is it nûmer dat jo sille brûke mei de kleurkaart.

You have your door's weight, mar de grafyk toant in tsiental kleuren. Choosing one that's "close enough" sil ferlitte jo doar unbalanced, straining de iepener en wêrtroch foartidige slijtage op rollers en hinges.

You match your door's accurate weight to the corresponding color on the chart. It's crucial to understand that the weight listed is for a pair of springs. A 140-pound door requires two 140-pound rated springs (Yellow), as each spring is designed to lift half the total load.

The color code[^1] system was created to make identification simple for professionals. The colors advance in 10-pound increments, allowing for very precise balancing. A perfectly balanced door should feel almost weightless when you lift it manually. You should be able to stop it halfway open and have it stay there. If it wants to fall down, your springs are too weak. If it wants to fly open, your springs are too strong. Even a 10-pound difference can create an imbalance that forces your electric opener to work much harder than it should, shortening its lifespan. This is why you should never "round up" or "round down." Use the exact weight of your door to find the exact color match.

Standard Color Chart for 7-Foot Doors

This is a typical chart used in the industry.

• The 10-Pound System: Each color represents an additional 10 pounds of lifting capacity. This standardization makes it easy to find the right part.
• Always Replace in Pairs: Extension springs work together. When one fails, the other has been subjected to the same number of cycles and stresses and is likely near failure itself. Replacing only one spring will create an immediate and dangerous imbalance.

Does a Taller Door Use a Different Color Chart?

You have an 8-foot tall garage door, but you used a standard chart. Now the new springs are stretched too far when the door is open, making a loud noise and losing power quickly.

Ja, taller doors require different springs and a different chart. A standard 7-foot door uses a 25-inch long spring. An 8-foot door needs a longer, 27-inch spring to handle the extra travel distance without being overstretched. The color code[^1]s for these longer springs are different.

This is one of the most common mistakes I see. An 8-foot door has to travel an extra 12 inches. If you use a standard 25-inch spring, you are stretching it far beyond its designed limit every single time you open the door. This will permanently damage the spring, causing it to lose its lifting force in a very short amount of time. It also puts the spring at high risk for a sudden, catastrophic failure. As a manufacturer, we produce these different spring lengths for this exact reason. De tried diameter en it oantal coils binne oars, wat betsjut dat harren krêft eigenskippen binne oars. Jo kinne net oannimme in "Blue" maitiid foar in 7-foet doar is itselde as in "Blauwe" maitiid foar in 8-foet doar. You must use a chart specific to your door's height.

It's a simple rule: the spring's length must match the door's height.

• Travel Ofstân: The distance a spring has to stretch is determined by the door's height. Hegere doarren betsjutte mear reizen.
• Konstruearre foar in spesifike stretch: In 25-inch maitiid is ûntworpen om feilich út te strekken 42 inches (foar in 7-foet doar). In 27-inch maitiid is ûntworpen om feilich út te strekken 48 inches (foar in 8-foet doar).
• De ferkearde kombinaasje mislearret: It brûken fan de ferkearde lingte sil altyd liede ta mislearring. De doar sil of net goed iepen/slute, or the springs will wear out in a matter of months instead of years.

Konklúzje

A color chart is a useful guide, but it is not enough. You must weigh your door and confirm its height to choose the correct and safe extension springs for your garage.
