Company Detail

Extension springs, also called tensile springs, are found in many applications, such as common household products,snow plows, garage doors and various types of spring tensioning devices.

Extension springs have hooks on their ends to attach them to the application. Various hook styles and configurations are available depending on the particular application.Unlike compression springs, extension springs do not have a solid stop to prevent overloading. For these reasons,design stresses are generally lower for extension than compression springs.
