Description
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.
