A rotating feeler gauge keeps a range of marked measuring leaves together in one compact, folding tool. Rotate the leaves open to access and select an individual blade, then fold them back for convenient storage and carrying. The pivoting design allows the blades to fan out through a full 360° rotation, making it easy to choose the leaf you need. Thickness markings are printed on the individual leaves to help identify a blade when checking narrow gaps and clearances. The marked thicknesses range from 0.05 mm to 1.00 mm in 0.05 mm increments. Its hinged, foldable layout keeps the gauge leaves organized in a single compact tool, ready for checking a gap and folding away after use. Keep the set close at hand for measuring tasks in the workshop or wherever a gap needs checking.
