Extension Springs

Extension springs are used in a wide variety of applications where a precise amount of force is required at a certain deflection. Extension springs are used to retract aircraft landing gear, to tether equipment to oil rigs in offshore applications, and on Class 8 heavy trucks as hood-assist springs to safely hold the hood in place for engine maintenance. Other examples include specialized springs implanted in roadways or around secure buildings to create barriers to provide additional protection from possible outside threats.

They can range dramatically in length (from 1/2-inch to 50 feet) and in the force they create (from a few ounces to thousands of pounds).
