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.

To keep the set complete, gauge leaves are riveted together in a fan design that folds up for portability.

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

These sets combine a wire gauge, a tapered-width feeler gauge, and a set of feeler gauges for tight spots in one tool.

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