AGD Group 3 Dial Indicators

DIAL SIZE 2 ¾"

These dial indicators are built to American Gage Design Group 3 specifications.
This group size offers a larger, more visible dial face for bigger fixtures and gages.

They are furnished with a lug back (with 90 degree mounting holes to be used
vertically or horizontally), a regular contact point ¼" long, and a dust cap.

The following charts below contain all standard group 3 dial indicators arranged by travel.
