The key feature is degree of rigidity and this is achieved by the following :
Large diameter fulcrum nut to stop side movement of legs
Thickness of legs
Smooth finish on points to enhance accurate performance
Measuring range of spring tools is the stated leg length
Size range available includes 3", 4", 6", 10", 12", 18", 24" and 36"
Outside & Inside Firm Joint Calipers
Rigidity is the key feature achieved by
Securely made hinge joint

Smoothly made measuring contacts
The measuring range with these is much larger than leg length. Outside calipers will measure approximately 25%-30% larger diameter than leg length.
