| Message: | The unique qualities of constant strength springs make them perfect for heavy moving parts. An example of this is the door to a moving van. It takes additional effort when you pull an open door down to get the first few inches of the door going – this is because the spring must be overcome with a full load (1.25x its diameter). url:http://www.sorwe-wiper.com |
