Gauges are 12” long and have finished ends marked with thickness.

Use these feeler gauge assortments to check gaps, alignment, and narrow slots.

A certificate of calibration traceable to NIST states that this gauge has passed a test for accuracy.

Since each thickness is a different color, there’s no need to read the feeler gauge to tell your measurement.

Keep a variety of leaf thicknesses on hand to confirm gaps are within tolerance.

To ensure accurate readings, these sets come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

Check slot widths and hole diameters with the markings on these gauges. Leaves in a variety of sizes are riveted together in a fan design—spread them out for use or fold them in for portability.

To measure thickness in areas where standard feeler gauges don’t fit, these sets have leaves with narrow ends.
