Inside Diameter Double-Turret Gage

This gage was designed to fit through a diameter much smaller than the one to be gaged.

A double-turret gage can check an I.D. up to two times larger than the hole it will pass through.

Single-turret gages can be designed for I.D.'s up to one and one-half times larger than the hole it will pass through.

Accurate gages have been supplied that will reach 36" deep.
