Other Info.
Constant force extension springs provide a huge range of application opportunities.
Springs can be extended in excess of 50 times the relaxed length of the spring,
and can be mounted on a bobbin or bush or free running in a cavity or recess.
Springs can be joined or laminated to provide increased force with minimal increases in space requirements.
