How Do I Know What Size Spring To Get For My Garage Door?

Choosing the right spring for your garage door is important for smooth operation. There are several things to consider. You need to know the wire size, inside diameter, length, wind direction, and the garage door’s weight. These are key to following a garage door spring sizing guide.

To figure out the wire size, count 20 coils on the spring and divide by 20. This gives you a correct measure. You can then check this against a garage door spring length chart. The inside diameter is often marked on the cones of the spring. Always measure the spring’s length after removing it to get it right.

Knowing the wind direction of torsion springs is crucial. They can be right-hand wind (clockwise) or left-hand wind (anticlockwise). This affects how the spring works and the door’s safety. Getting this right ensures the garage door spring calculator is accurate.

For extension springs, look at the spring’s length and the door’s weight. The door’s weight needs exact measurement. It impacts how well the spring works. If needed, use the SSC app for an accurate size.

Industry standards help with drums, which usually have part numbers. This makes finding the right parts easier. Drums differ in design. Hi-lift drums help open the door faster. For vertical movement, vertical lift drums are used in commercial garages.

Standard lift garage doors need about 12 inches of headroom. But, extension spring systems might only need 8.5 inches. Knowing this helps choose the right spring.

Torsion springs balance the garage door’s weight. They sit horizontally above the door. These springs are made from materials like beryllium copper and stainless steel. This affects their life and work. Extension springs stretch out beside the door. They have a colour code for weight capacity.

When unsure, always ask a professional to measure and repair springs. It’s risky to do it alone. The right spring size means your garage door works safely and well.
