Category Details
This category includes various types of extension springs.
- Helical spring that absorbs and stores energy by resisting a pulling force. When extended, it stores energy, and when released, it redistributes that energy to return to its original, coiled shape.
- Typically used to provide a pulling force between two objects, often with hooks or loops on either end for attachment.
- This category includes short and long lengths. An expanded range may be available on special order. Please enquire.
