10 best heavy duty torsion springs
Heavy-duty torsion springs are mechanical components used in various applications, including door closers and other hardware systems. These springs are designed to store and release mechanical energy when twisted or rotated, providing force to move or control various mechanisms, such as doors. Here's what you should know about heavy-duty torsion springs:
Function: Torsion springs operate based on the principle of torque or rotational force. When twisted or wound, they store potential energy, which is released when the spring unwinds, exerting a torque or rotational force in the opposite direction.
Materials: Heavy-duty torsion springs are typically made from materials like high-strength steel or stainless steel. The choice of material depends on the application's requirements, including the desired strength and resistance to corrosion.
Size and Shape: These springs come in various sizes and shapes, depending on the specific application. They can be coiled, helical, or spiral in design, with variations in diameter, length, and wire thickness to suit different needs.
Load Capacity: Heavy-duty torsion springs are designed to handle higher loads and provide greater torque compared to standard or lighter-duty torsion springs. The load capacity is determined by factors like the spring's dimensions, material, and manufacturing quality.
Usage in Door Closers: In the context of door closers, heavy-duty torsion springs are often employed to control the closing and opening of doors, particularly heavy or large doors. They store energy when the door is opened and release it gradually to ensure a controlled and safe closing motion.
Adjustability: Some door closers with heavy-duty torsion springs may allow for adjustment to control the closing speed and force, providing flexibility to meet specific requirements.
Maintenance: Proper maintenance is essential to ensure the longevity and functionality of heavy-duty torsion springs. This may include regular lubrication and inspection to identify signs of wear or fatigue.
Safety: Due to the significant torque they can generate, safety precautions should be observed when working with heavy-duty torsion springs. Mishandling or improper installation can lead to accidents or injuries.
Customization: In certain cases, heavy-duty torsion springs may be custom-made to meet the unique requirements of specific applications. Customization can include variations in size, load capacity, and design.
Applications: Aside from door closers, heavy-duty torsion springs find use in a wide range of applications, including garage doors, industrial machinery, automotive systems, and more, wherever controlled rotational force is needed.
In summary, heavy-duty torsion springs are robust mechanical components designed to store and release energy through twisting or winding motions. They are commonly used in door closers and other hardware systems where controlled torque and rotational force are essential for safe and efficient operation. These springs are available in various sizes and materials to suit diverse industrial and commercial needs.

User questions & answers
| Question: | Is there any way to adjust the tension? I have to push hard on the lid until it closes or it will just open back up |
| Answer: | Put oil/grease on spring to keep them from corroding and sticking which causes them to snap. |
| Question: | Where do I find the installation directions? I don’t have the instructions |
| Answer: | Yes... I don't see any issues with that. Adjust your spring tension and good to go. |
| Question: | So can 4 hold a weight of 120lb. lid |
| Answer: | Yes, however I had a lot of trouble getting the correct order straightened out. They ended sending me 3 sets of spr;ings, tghey still owe me a refund. I needed 2"x 1/4" x 34" and the ordering was very confusing to me. |
| Question: | The only instructions with my hinged were in Chinese. Can someone send me them in English |
| Answer: | This should work. As G. Wald said, make certain you count the number of turns you release the springs. They should both get the same number of turns so you have an even amount of torque at each side of the door. |

User questions & answers
| Question: | does this keep the door from slamming shut? I noticed some reviews on similar products say their door slams at the very last part of closing |
| Answer: | Not that I’ve found. These are tricky. Try Shutting the lid until you meet resistance. Then just let it be. It had a delayed soft close. But if you try and force it, it won’t close. |
| Question: | I purchased and installed it. however, now that it is getting colder where i live in maine, the mechanism is freezing. what can be done |
| Answer: | You probably have them. It is a single sheet of glossy paper with a couple of pictures on it. I mistook it as an add for more of their products. However, they instructions are very vague and somewhat misleading. The box side thickness needs to be 3/4 inches (20 mm) with hinge pin on the outside edge. I used a piano hinge. The top edge of the "T" is 3/8 inches (10 mm) down from top inside edge of box side. After a lot of trial and error, I found the lid needs to be at 85 degrees, not 90. The lid will stay open and requires very little effort to start the closing process. At 90 degrees, it takes a lot of effort to start the closing process. |
| Question: | will this work on a wood screen door that has spring hinges? And I need it close fully, but softly. No slamming |
| Answer: | yes, they will work |
| Question: | Can you use these outside on a Privacy fence gate? I would probably use two. The wood gate isn't that big or heavy |
| Answer: | Hi, please email us so that we can send it, thanks |
