CALIPERS AND DIVIDERS ARE NOT ALL THE SAME

by Maria Baker,

Calipers and dividers may look similar but there are many

differences between brands. 
To get good quality at a fair price check the following
features for wing dividers, spring dividers, and firm joint and spring
calipers.
·
Rugged legs
·
Box type hinge joint
·
Hardened points – to ensure the points will have
long wear life because hardened steel is a high performing material.
·
Sizes available should be 6”, 8”, 12”, 18” and
24”

Rigidity is the key feature achieved by:

stop side movement of legs.

of the tool
·

correctly.
·
Measuring range of spring tools is the stated
leg length range.
·
Size range-3”, 4”, 6”, 8”, 10”, 12”, 18” 24”

Rigidity is the key feature achieved by:
·
Securely made hinge joint and well-proportioned
legs

length.  The outside calipers will
measure approximately 25%-30% larger diameter than leg length.
·

and 60” although larger sizes can be available.
