Starrett 653G granite comparator stand with Crystal Pink Grade A granite base measuring 12" L x 8" W x 2" THK. Includes an 11-1/2" rod with 1-31/64" diameter and a 1-1/2" upright post. Provides a stable, vibration-resistant platform for dial indicators and precision measurement tools.

The Starrett 653 Individual Component is a bench-type comparator gage that is ruggedly built for in-process and final inspection work. The dial indicator can be adjusted vertically and locked in any position. A sliding ring with locking screw below the beam permits swinging the indicator to either side. The ring also acts as a safety device, preventing the beam from accidentally dropping. There is a fine adjustment on the beam for final indicator setting. The hand lifting lever on the indicator raises the spindle and releases it to contact the work. Left hand lever furnished unless otherwise specified. Both gages have a maximum vertical capacity of 9-1/4" (235mm) and a throat depth of 5" (125mm) and a vertical indicator fine adjustment of up to 1/2" (12.7mm).
