    Securely mount indicators to metal surfaces with the magnetic base on these holders. They have a switch that releases the magnet for easy setups.
    Fine-Adjustment Arm—Holders with a fine-adjustment arm have a knob on the arm that lets you precisely adjust the arm’s angle or move the indicator up and down.
    2 Arms—Holders with two arms have an extra long reach. Bend them where the two arms meet to change the direction of your indicator. You can also remove an arm if you’re using these holders in a tight space.
    V-Grooved Base—Holders with a V-grooved base can be mounted on flat or curved metal surfaces.
