6" outside spring caliper used to measure the external size of an object.

Outside calipers are useful for transferring measurements from a workpiece to a rule. They are a flexible solution when the work has complex shapes or when measuring round stock.

These calipers have a flat leg design and open to a maximum of 6" (150 mm). The polished steel legs are easily adjusted over the entire range and adjustments can be easily fixed with a quick nut.
