Extension Spring Customized Precision Spring Zinc Nickl

An extension spring is the opposite of a compression spring, as push now becomes pull. Like compression springs they come in a variety of shapes and sizes. One of the most critical factors with these extension springs is the design of the hook. If done incorrectly, this can result in failure.
At Lizhou Hardware Spring we use special computer extension spring design software on every application to ensure proper spring life and design correctness.
