Yale YFS / YFS-A Spring tensioners

Spring tensioners model YFS
Capacity 0.5 - 10.0 kg
Spring tensioners with ratchet locking device model YFS-A
Capacity 2 - 10.0 kg
Spring tensioners are designed to retract the cable when no force is applied. An amount of downward force must be continually applied to keep the suspended object at its extended position.
The torque output of the rewind spring increases as the cable is extended, retracting the suspended object to the uppermost adjusted position when released.
