An extension rod is an accessory used to increase the reach of a dial indicator.It’s
a cylindrical component with a threaded end that screws into the dial indicator’s
stem. This allows for measurements in deeper or more inaccessible areas.

Key Features:

• Increased reach: Enables measurement in deeper cavities
  or on larger components.
• Precision: High-quality extension rods maintain the accuracy
  of the dial indicator.
• Material: Typically made from hardened steel for durability
  and precision.
• Thread compatibility: Matches the thread of the dial indicator’s
  stem.
