(Solid Green)
Efficient Operating Range is 25% to 50% deflection of free length.Maximum deflection is 50%; Long Life deflection is 40%; Optimum Life deflection is 25%.Deflection beyond this Efficient Operating Range could result in premature spring failure. Travel to Solid is a reference dimension only and should never be approached during use.
