Starrett Feeler Gauge Sets for Tight Spots

To measure thickness in areas where standard feeler gauges don’t fit, these sets have leaves with narrow ends. They're used to check gaps, alignment, and narrow slots. Sets include leaves in a variety of thicknesses that are riveted together in a fan design that folds up for portability. Each leaf is marked with thickness. Leaf-securing locks hold individual gauge leaves in place.
