When it comes to garage doors, accuracy is key. You don't want to end up with the wrong spring because you're guessing, so it's important to measure the components correctly. Most residential garage doors are seven or eight feet tall, and seven-foot doors generally use a 25-inch spring while eight-foot doors use a 27-inch spring. However, it's best to measure the components by hand to ensure accuracy.
When measuring, make sure the garage door is closed. It's common for most residential garage doors to be seven or eight feet tall, but you'll want to measure the components carefully since garage door springs are tightly wound due to the large amount of tension they contain. If released suddenly, they can cause serious injury or even death. Fortunately, most garage doors don't require sophisticated parts and can use universal parts for garage doors. The term 'industry standard' is used to refer to standard garage doors, and if you submit photographs of your garage door, these springs can be recommended if your door is industry standard.
These drums pull the cables which pull the bottom of the door to balance the weight of the garage door. In some cases, when one torsion spring on a garage door breaks, either the left or right one, the other one may also be nearing the end of its life cycle. As a precautionary measure, no coil should be touched while the torsion spring is still in the bars above the garage door. When searching for a specific torsion spring, a list of compatible springs with the same lift but with a different life cycle will appear. Each garage door requires a specific spring with specific specifications depending on the type, height and weight of the garage door.
To get an accurate measurement, all you need to do is measure from the first coil on one end to the last coil on the other end of the garage door spring, including any coils found in the cone. Springs that are too small or too large can damage your garage door and create a safety hazard. When a garage door is in motion, each spring grows by a single coil in length at each turn.
